A constant catch regime ended up with a fishery crash and closure (2005–2009) after a series of recruitment failures. Precautionary advices had been disregarded due to their inability to predict the size of the population during the first half of the year when the major fishery takes place. The crash triggered the EU to develop a long-term management plan in 2008. In the absence of a recruitment indicator, biological risk was minimized through a close coupling between assessment, advice and management, changing the management year to start just after the spring surveys on adults. A major improvement arrived in 2014 by the incorporation of an early recruitment indicator from an autumn acoustic survey on juveniles. This allowed additional exploitation of the resource at similar risk levels. Accordingly, TACs are nowadays set after the recruit survey on a management calendar basis. The interactive collaboration between fishers, scientists, and managers allowed inclusion of the stakeholders’ preferences for a biomass-based catch bounded harvest strategy suitable for these valuable fisheries. This strategy allows catches between a minimum and maximum TAC level, to account for an economically viable minimum activity when approaching a minimum biomass threshold level, and for the limited market absorption capacity when exceeding an upper biomass threshold level, respectively. Such strategy was adopted by consensus and supposed a successful participatory process in fishery management.} } @article{https://doi.org/10.1111/faf.12721, author = {Dowling, Natalie A. and Wilson, Jono R. and Cope, Jason M. and Dougherty, Dawn T. and Lomonico, Serena and Revenga, Carmen and Snouffer, Brian J. and Salinas, Natalio Godoy and Torres-Cañete, Felipe and Chick, Rowan C. and Fowler, Ashley M. and Parma, Ana M.}, title = {The FishPath approach for fisheries management in a data- and capacity-limited world}, journal = {Fish and Fisheries}, volume = {n/a}, number = {n/a}, pages = {}, keywords = {data limited, decision-support, fisheries management, harvest strategies, management strategies, sustainability}, doi = {https://doi.org/10.1111/faf.12721}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1111/faf.12721}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1111/faf.12721}, abstract = {Abstract Successful fisheries management systems tend to be underpinned by harvest strategies, specifying formally agreed data collection systems, assessment approaches and management measures used to regulate fishing pressure. While harvest strategies can be effective even in data- and capacity-limited (DCL) situations, their development remains challenging in such contexts. We present a process and decision-support tool, FishPath, to guide the identification of suitable harvest strategy component options given often debilitating conditions: (i) resource limitations and lack of technical management capacity; (ii) ‘uniqueness’ of DCL fisheries; (iii) the concept of harvest strategies is unfamiliar to managers and scientists, and the universe of options is hard to navigate; and (iv) the lack of an effective participatory process to identify solutions tailored to local contexts. These conditions can lead to either management paralysis or generic solutions that may be poor fits to specific conditions. The FishPath Tool uses a diagnostic questionnaire that elicits the key characteristics and specific circumstances of a fishery. It compares these with the requirements of alternative options from an inventory of possible harvest strategy components, identifies where these requirements are met and provides customised, transparent guidance on the appropriateness of component options of a harvest strategy, specific to the fishery of interest and its governance context. The FishPath Process is a facilitated multi-stakeholder, participatory engagement process aimed to set fisheries on the path to develop a harvest strategy. The FishPath Process and Tool combine to ensure a bottom-up, documented, transparent, replicable and efficient process.} } @article{cousido2022surplus, title={Surplus production models: a practical review of recent approaches}, author={Cousido-Rocha, Marta and Pennino, Maria Grazia and Izquierdo, Francisco and Paz, Anxo and Lojo, Davinia and Tifoura, Amina and Zanni, Mohamed Yosri and Cervi{\~n}o, Santiago}, journal={Reviews in Fish Biology and Fisheries}, pages={1--18}, year={2022}, publisher={Springer} } @article{doi:10.1139/cjfas-2021-0213, author = {Batts, Luke and Minto, Cóilín and Gerritsen, Hans and Brophy, Deirdre}, title = {Numbers or mass?

Models were tested within a simulation framework as well as on the real stock of white-bellied anglerfish (Lophius piscatorius) in the Celtic Seas and Northern Bay of Biscay. For the simulated stocks, estimates from the biomass-based two-stage models were close to the true values in certain scenarios, but were sensitive to selectivity assumptions and configuration of growth within the model. CSA was more robust to selectivity assumptions, performing well in all simulated stock scenarios. Overall, results indicated that CSA was a robust stock assessment model but with relatively low precision, whereas the Schnute model was precise but required growth and mean fish weight data unaffected by selectivity. } } @article{bach2022, title={Intervene or wait?

Given the uncertainty associated with complex social-ecological systems and the potentially irreversible consequences of delayed action for biodiversity and livelihoods, managers tend to simply intervene as soon as possible by precaution. However, refraining from intervening when the situation allows can be beneficial, notably by saving critical management resources. We introduce a strategy for managers to decide, based on monitoring, whether intervention is required or if waiting is possible. This study evaluates the performance of this waiting strategy compared to a strategy of unconditional intervention at every opportunity. We built an individual-based model of conservation conflict between a manager aiming to conserve an animal population and farmers aiming to maximize yield by protecting their crop from wildlife damage. We then simulated a budget-constrained adaptive management over time applying each strategy, while accounting for uncertainty around population dynamics and around decision making of managers and farmers. Our results showed that when the decision for the manager to intervene was based on a prediction of population trajectory, the waiting strategy performed at least as well as unconditional intervention while also allowing managers to save resources by avoiding unnecessary interventions. Under difficult budgetary constraints on managers, this waiting strategy ensured as high yields as unconditional intervention while significantly improving conservation outcomes by compensating managers’ lack of resources with the benefits accrued over waiting periods. This suggests that waiting strategies are worth considering in conservation conflicts because they can facilitate equitable management with a more efficient use of management resources, which are often limiting in biodiversity conservation.}, doi={10.5751/ES-13341-270303}, publisher={The Resilience Alliance} } @article{10.1371/journal.pone.0269543, doi = {10.1371/journal.pone.0269543}, author = {Scott, Finlay AND Yao, Nan AND Scott, Robert Dryden}, journal = {PLOS ONE}, publisher = {Public Library of Science}, title = {AMPLE: An R package for capacity building on fisheries harvest strategies}, year = {2022}, month = {06}, volume = {17}, url = {https://doi.org/10.1371/journal.pone.0269543}, pages = {1-14}, abstract = {Fisheries harvest strategies are formal frameworks that represent a best-practice approach for sustainable fisheries management. A key component of a harvest strategy is a ’pre-agreed rule’, known as a harvest control rule (HCR), that sets fishing opportunities, e.g. catch limits, based on an estimate of fish stock status, e.g. estimated stock biomass. The harvest strategy development process is driven by stakeholders who are required to make a range of informed decisions, including on the selection of the preferred HCR. Capacity building may be required to facilitate the stakeholder engagement, particularly regarding the technical components of harvest strategies, including HCRs. The AMPLE package for R provides three interactive apps that support capacity building and stakeholder engagement on HCRs. These apps have been used during in-country national workshops around the western and central Pacific Ocean (WCPO) to support the development of harvest strategies for the Western and Central Pacific Fisheries Commission. These apps include several novel features: they take users from a gentle introduction to how HCRs work, to using methods for testing, comparing and selecting a preferred HCR from a suite of candidates. They include an introduction to the impact of uncertainty on the performance of an HCR, introduce performance indicators and discuss methods for selecting the preferred HCR based on management objectives. As such they provide a more detailed overview of HCRs than currently existing alternatives. These apps provide an effective platform for hands-on learning and have proven to be successful at supporting capacity building on HCRs in the WCPO. For example, using them for group activities and competitions stimulated productive discussions and increased understanding. As the model fishery in AMPLE is generic and not based on a real example, the apps will also be of interest to scientists, managers and stakeholders developing harvest strategies in other regions.}, number = {6}, } @article{10.1093/icesjms/fsac043, author = {Kell, Laurence T and Minto, Cóilín and Gerritsen, Hans D}, title = "{Evaluation of the skill of length-based indicators to identify stock status and trends}", journal = {ICES Journal of Marine Science}, year = {2022}, month = {03}, issn = {1054-3139}, doi = {10.1093/icesjms/fsac043}, url = {https://doi.org/10.1093/icesjms/fsac043}, note = {fsac043}, eprint = {https://academic.oup.com/icesjms/advance-article-pdf/doi/10.1093/icesjms/fsac043/43058181/fsac043.pdf}, } @article{magnussonfisheries, title={Fisheries data management at GFCM Review and recommendations}, author={Magnusson, Arni}, year={2022} } @article{winker2022consistency, title={Consistency and Robustness testing of candidate reference point systems for North East Atlantic stocks}, author={Winker, Henning and Cardinale, Massimiliano and Mosqueira, Iago and Kell, Laurance and Konrad, Christoph and Gras, Michael and Sharma, Rishi and Lordan, Colm}, year={2022} } @article{https://doi.org/10.1111/faf.12637, author = {Ovando, Daniel and Free, Christopher M. and Jensen, Olaf P. and Hilborn, Ray}, title = {A history and evaluation of catch-only stock assessment models}, journal = {Fish and Fisheries}, volume = {23}, number = {3}, pages = {616-630}, keywords = {catch-only models, data-limited assessment, global fisheries, stock assessment, stock reduction analysis}, doi = {https://doi.org/10.1111/faf.12637}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1111/faf.12637}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1111/faf.12637}, year = {2022} } @article{andmauricio2021standardized, author={Ortiz de Zarate, V and Ortiz, M}, title={Standardized Catch Per Unit Of Effort Of Albacore (Thunnus alalunga) In The Northeast Atlantic From The Spanish Bait Boat Fleet For Period: 1981-2019}, journal={Collect.

This study explored the application of a genetic algorithm to an empirical catch rule and found that this approach could substantially improve the performance of the catch rule. The optimized parameterization and the magnitude of the improvement were dependent on the specific stock, stock status, and definition of the fitness function. The genetic algorithm proved to be an efficient and automated method for tuning the catch rule and removed the need for manual intervention during the optimization process. Therefore, we conclude that the approach could also be applied to other management procedures, case-specific tuning, and even data-rich stocks.

In data-limited stock assessments, M usually relies on a range of empirically or theoretically derived M estimates, which can vary vastly. This paper aims at evaluating the impact of this variability in M using seven Mediterranean stocks as case studies of statistical catch-at-age assessments for information-limited fisheries. The two main bodies carrying out stock assessments in the Mediterranean and Black Seas are European Union’s Scientific Technical Economic Committee for Fisheries (STECF) and Food and Agriculture Organization’s General Fisheries Commission for the Mediterranean (GFCM). Current advices in terms of fishing mortality levels is based on a single ‘best’ M assumption which is agreed by stock assessment expert working groups, but uncertainty about M is not taken into consideration. Our results demonstrate that not accounting for the uncertainty surrounding M during the assessment process can lead to strong underestimation or overestimation of fishing mortality, potentially biasing the management process.

In this study of the North Sea fish community, we consider several possible MSY candidates, and evaluate them in terms of their ability to produce optimum long-term yield whilst avoiding unacceptable risk of stock impairment. We perform this evaluation with an ensemble of size-structured models using a management strategy evaluation approach, in which harvest control rules (HCRs) are used to determine levels of fishing as a function of the proposed MSY target and stock status, taking account of recruitment and model parameter uncertainties. We find that HCRs of the type considered here are always useful in the scenarios we tested, as they reduce overfishing risk much more than average long-term yield. This is independent of the precise form of the HCR, so it is more important to implement one rigorously than obsess over the rule details. For a lax definition of overfishing, which accepts relatively severe stock depletion (B \\< 10\\% B0), and using HCRs, risks are “low” across all strategies, and the Nash equilibrium is the best performing MSY approach considered here. For more stringent definitions of “at risk” (e.g. likelihood of B \\< 20\\% of B0), the application of HCRs can allow a range of alternative formulations of MSY.

The method applies management strategy evaluation procedures that employ an ecosystem model of the North Sea and its fisheries as the operating model. Taking five key dimensions of the proposed plan, it identifies those areas that are key to its successful performance. Overwhelmingly, choices in the options for the implementation of regulatory measures on discarding practices outweigh the effects of options related to fishing within ranges associated with ‘pretty good yield’, the way that biomass conservation safeguard mechanisms are applied and the timeframe for achieving fishing mortality targets. The impact of safeguard options and ranges in fishing mortality become important only when stock biomass is close to its reference points. The fifth dimension–taking into account wider conservation and ecosystem objectives—reveals that discard policy has a big impact on conservation species, but also that the type of harvest control rule can play an important role in limiting risks to stocks by ‘applying the brakes’ early. The consequences to fisheries however is heightened risk to their viability, thus exposing the sustainability trade-offs faced with balancing societal pressures for blue growth and enhanced conservation. It also reveals the wider ecosystem impacts that emphasise the connectivity between the demersal and pelagic realms, and thus, the importance of not treating the demersal NSMAP in isolation from other management plans. When stocks are below their biomass reference points, low F strategies lead to better long term economic performance, but for stocks consistently above biomass reference points, high F strategies lead to higher long term value.

Considering that the biological components of a population can be partitioned into discrete spatial units, we extended this idea into a property of additivity of sub-population abundances. If the additivity results hold true for putative sub-populations, then assessment results based on sub-populations will provide information to develop and monitor the implementation of finer scale/local management. The simulation study confirmed that when sub-populations are independent and not too heterogeneous with regards to productivity, the sum of stock assessment model estimates of sub-populations’ SSB is similar to the SSB estimates of the meta-population. It also showed that a strong diffusion process can be detected and that the stronger the connection between SSB and recruitment, the better the diffusion process will be detected. On the other hand it showed that weak to moderate diffusion processes are not easy to identify and large differences between sub-populations productivities may be confounded with weak diffusion processes.

Unassessed fisheries are particularly predominant in developing countries and in small-scale fisheries, where they are important for food security. Several catch-only methods based on time series of fishery catch and commonly available life-history traits have been developed to estimate stock status (defined as biomass relative to biomass at maximum sustainable yield: B/BMSY). While their stock status performance has been extensively studied, performance of catch-only models as a management tool is unknown. We evaluated the extent to which a superensemble of three prominent catch-only models can provide a reliable basis for fisheries management and how performance compares across management strategies that control catch or fishing effort. We used a management strategy evaluation framework to determine whether a superensemble of catch-only models can reliably inform harvest control rules (HCRs). Across five simulated fish life histories and two harvest-dynamic types, catch-only models and HCR combinations reduced the risk of overfishing and increased the proportion of stocks above BMSY compared to business as usual, though often resulted in poor yields. Precautionary HCRs based on fishing effort were robust and insensitive to error in catch-only models, while catch-based HCRs caused high probabilities of overfishing and more overfished populations. Catch-only methods tended to overestimate B/BMSY for our simulated data sets. The catch-only superensemble combined with precautionary effort-based HCRs could be part of a stepping stone approach for managing some data-limited stocks while working towards more data-moderate assessment methods.}, year = {2018} } @article{doi:10.1002/nafm.10047, author = {Sagarese, Skyler R. and Rios, Adyan B. and Cass-Calay, Shannon L. and Cummings, Nancie J. and Bryan, Meaghan D. and Stevens, Molly H. and Harford, William J. and McCarthy, Kevin J. and Matter, Vivian M.}, title = {Working Towards a Framework for Stock Evaluations in Data-Limited Fisheries}, journal = {North American Journal of Fisheries Management}, volume = {38}, number = {3}, pages = {507-537}, doi = {10.1002/nafm.10047}, url = {https://afspubs.onlinelibrary.wiley.com/doi/abs/10.1002/nafm.10047}, eprint = {https://afspubs.onlinelibrary.wiley.com/doi/pdf/10.1002/nafm.10047}, abstract = {Abstract Data-limited approaches to managing fisheries are widespread in regions where insufficient data prevent traditional stock assessments from determining stock status with sufficient certainty to be useful for management.

In this study, we present a framework for comparison and implementation of data-limited methods, including the static Status Quo approach, which uses average catch landings. Candidate species for stock evaluation were identified through a data triage and included Yellowtail Snapper Ocyurus chrysurus (Puerto Rico), Queen Triggerfish Balistes vetula (St. Thomas and St. John), and Stoplight Parrotfish Sparisoma viride (St. Croix). Feasible data-limited methods, based on data availability and quality, included empirical indicator approaches using relative abundance (i.e., catch per unit effort) or mean length. Results from the management strategy evaluation support the use of adaptive data-limited methods, which incorporate feedback in contrast to the static Status Quo approach. The proposed framework can help guide the development of catch advice for dynamic fisheries management in data-limited regions.}, year = {2018} } @article{doi:10.1111/faf.12232, author = {Nielsen, J Rasmus and Thunberg, Eric and Holland, Daniel S and Schmidt, Jorn O and Fulton, Elizabeth A and Bastardie, Francois and Punt, Andre E and Allen, Icarus and Bartelings, Heleen and Bertignac, Michel and Bethke, Eckhard and Bossier, Sieme and Buckworth, Rik and Carpenter, Griffin and Christensen, Asbjørn and Christensen, Villy and Da-Rocha, José M and Deng, Roy and Dichmont, Catherine and Doering, Ralf and Esteban, Aniol and Fernandes, Jose A. and Frost, Hans and Garcia, Dorleta and Gasche, Loic and Gascuel, Didier and Gourguet, Sophie and Groeneveld, Rolf A and Guillén, Jordi and Guyader, Olivier and Hamon, Katell G and Hoff, Ayoe and Horbowy, Jan and Hutton, Trevor and Lehuta, Sigrid and Little, L Richard and Lleonart, Jordi and Macher, Claire and Mackinson, Steven and Mahevas, Stephanie and Marchal, Paul and Mato-Amboage, Rosa and Mapstone, Bruce and Maynou, Francesc and Merzéréaud, Mathieu and Palacz, Artur and Pascoe, Sean and Paulrud, Anton and Plaganyi, Eva and Prellezo, Raul and van Putten, Elizabeth I and Quaas, Martin and Ravn-Jonsen, Lars and Sanchez, Sonia and Simons, Sarah and Thébaud, Olivier and Tomczak, Maciej T and Ulrich, Clara and van Dijk, Diana and Vermard, Youen and Voss, Rudi and Waldo, Staffan}, title = {Integrated ecological–economic fisheries models—Evaluation, review and challenges for implementation}, journal = {Fish and Fisheries}, volume = {19}, number = {1}, pages = {1-29}, keywords = {bio-economic models, comparative model evaluation, fisheries management advice, integrated ecological–economic fisheries models, marine spatial planning and cross-sector management, performance criteria and scales and risks, use and acceptance and implementation and communication and flexibility and complexity}, doi = {10.1111/faf.12232}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1111/faf.12232}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1111/faf.12232}, abstract = {Abstract Marine ecosystems evolve under many interconnected and area-specific pressures. To fulfil society's intensifying and diversifying needs while ensuring ecologically sustainable development, more effective marine spatial planning and broader-scope management of marine resources is necessary. Integrated ecological–economic fisheries models (IEEFMs) of marine systems are needed to evaluate impacts and sustainability of potential management actions and understand, and anticipate ecological, economic and social dynamics at a range of scales from local to national and regional. To make these models most effective, it is important to determine how model characteristics and methods of communicating results influence the model implementation, the nature of the advice that can be provided and the impact on decisions taken by managers. This article presents a global review and comparative evaluation of 35 IEEFMs applied to marine fisheries and marine ecosystem resources to identify the characteristics that determine their usefulness, effectiveness and implementation. The focus is on fully integrated models that allow for feedbacks between ecological and human processes although not all the models reviewed achieve that. Modellers must invest more time to make models user friendly and to participate in management fora where models and model results can be explained and discussed. Such involvement is beneficial to all parties, leading to improvement of mo-dels and more effective implementation of advice, but demands substantial resources which must be built into the governance process. It takes time to develop effective processes for using IEEFMs requiring a long-term commitment to integrating multidisciplinary modelling advice into management decision-making.}, year = {2018} } @article{ ISI:000404555100008, Author = {Anderson, Sean C. and Cooper, Andrew B. and Jensen, Olaf P. and Minto, Coilin and Thorson, James T. and Walsh, Jessica C. and Afflerbach, Jamie and Dickey-Collas, Mark and Kleisner, Kristin M. and Longo, Catherine and Osio, Giacomo Chato and Ovando, Daniel and Mosqueira, Iago and Rosenberg, Andrew A. and Selig, Elizabeth R.}, Title = {{Improving estimates of population status and trend with superensemble models}}, Journal = {{FISH AND FISHERIES}}, Year = {{2017}}, Volume = {{18}}, Number = {{4}}, Pages = {{732-741}}, Month = {{JUL}}, Abstract = {{Fishery managers must often reconcile conflicting estimates of population status and trend.

This approach uses predictions from multiple models as covariates in an additional ``superensemble{''} model fitted to known data. We evaluated the potential for ensemble averages and superensemble models (ensemble methods) to improve estimates of population status and trend for fisheries. We fit four widely applicable data-limited models that estimate stock biomass relative to equilibrium biomass at maximum sustainable yield (B/BMSY). We combined these estimates of recent fishery status and trends in B/BMSY with four ensemble methods: an ensemble average and three superensembles (a linear model, a random forest and a boosted regression tree). We trained our superensembles on 5,760 simulated stocks and tested them with cross-validation and against a global database of 249 stock assessments. Ensemble methods substantially improved estimates of population status and trend. Random forest and boosted regression trees performed the best at estimating population status: inaccuracy (median absolute proportional error) decreased from 0.42 -0.56 to 0.32 -0.33, rank-order correlation between predicted and true status improved from 0.02 - 0.32 to 0.44 - 0.48 and bias (median proportional error) declined from - 0.22 - 0.31 to - 0.12 - 0.03. We found similar improvements when predicting trend and when applying the simulation-trained superensembles to catch data for global fish stocks. Superensembles can optimally leverage multiple model predictions; however, they must be tested, formed from a diverse set of accurate models and built on a data set representative of the populations to which they are applied.}}, Publisher = {{WILEY}}, Address = {{111 RIVER ST, HOBOKEN 07030-5774, NJ USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Anderson, SC (Reprint Author), Univ Washington, Sch Aquat \& Fishery Sci, Seattle, WA USA.

It is foreseen that the policy will affect the use of fishing opportunities and hence the economic performance of the fleets. The problem with fishing opportunities could be solved if single-stock total allowable catches (TACs) could be achieved simultaneously for all the stocks. In this study, we evaluate the economic impact of the landing obligation policy on the Spanish demersal fleet operating in the Iberian Sea region. To generate TAC advice, we used two sets of maximum sustainable yield (MSY) reference points, the single-stock MSY reference points defined by ICES and a set of multistock reference points calculated simultaneously using a bioeconomic optimization model. We found that the impact of the landing obligation is time and fleet dependent and highly influenced by assumptions about fleet dynamics. At fishery level, multistock reference points mitigate the decrease in the net present value generated by the implementation of the landing obligation. However at fleet level, the effect depends on the fleet itself and the period. To ensure the optimum use of fishing opportunities, the landing obligation should be accompanied by a management system that guarantees consistency between single-stock TACs. In this regard, multistock reference points represent an improvement over those currently in use. However, further investigation is necessary to enhance performance both at fleet level and in the long term.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Garcia, D (Reprint Author), Marine Res Div, Sukarrieta, Spain.

We investigated 19 European fish stocks to test the hypothesis that the 95\% PGY yield range is inherently precautionary with respect to impairing recruitment. An F-MSY range was calculated for each stock as the range of fishing mortalities (F) that lead to an average catch of at least 95\% of MSY in long-term simulations. Further, a precautionary reference point for each stock (F-P.05) was defined as the F resulting in a 5\% probability of the spawning-stock biomass falling below an agreed biomass limit below which recruitment is impaired (B-lim) in long-term simulations. For the majority of the stocks analysed, the upper bound of the F-MSY range exceeded the estimated F-P.05. However, larger fish species had higher precautionary limits to fishing mortality, and species with larger asymptotic length were less likely to have F-MSY ranges impairing recruitment.

Recent changes in stock structures, conditions and stock mixing between eastern and western Baltic cod can jeopardize the reliability of stock assessments and of the fishery economy. We modelled how different management, individual vessel decision-making, and stock growth and mixing scenarios have induced alternative individual vessel spatial effort allocation and economic performance by affecting fishing costs and by changing the relative stock abundance and size distribution. Stock mixing heavily influences profit and stock abundance for stocks that have experienced increased fishing mortality (F) levels. Western cod F has increased from a higher total allowed catches (TAC) advised in the medium-term due to the westward migration of eastern cod while eastern cod F has increased from reduced growth in the east. Greater pressures on western cod and decreased eastern cod growth and conditions greatly reduce the overall cod spawning stock biomass, thus changing the landing size composition and associated fishery profits. As a cumulative effect, fishing efforts are redirected towards western areas depending on management (quotas). However, total profits are less affected when traditional fishing opportunities and switching possibilities for other species and areas are maintained. Our evaluation indicates that current management mechanisms cannot correct for potential detrimental effects on cod fisheries when effort re-allocation changes landing origins. By investigating different economic starting conditions we further show that Baltic cod mis-management could have resulted in unintended unequal (skewed) impacts and serious consequences for certain fleets and fishing communities compared with others. Our management strategy evaluation is instrumental in capturing non-linear effects of different recommendations on sustainability and economic viability, and we show that fixed F-values management is likely not an attainable or sufficient goal in ensuring the sustainability and viability of fisheries and stocks given changing biological conditions.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Bastardie, F (Reprint Author), Tech Univ Denmark, Nat Inst Aquat Resources DTU Aqua, Kongens Lyngby, Denmark.

The North Sea mixed fisheries are a representative example of an issue that is generic across most demersal fisheries worldwide, with the diversity of species and fisheries inducing numerous biological and technical interactions. Building on a rich knowledge base for the understanding and quantification of these interactions, new approaches have emerged. Recent paths towards operationalizing MSY at the regional scale have suggested the expansion of the concept into a desirable area of ``pretty good yield{''}, implemented through a range around FMSY that would allow for more flexibility in management targets. This article investigates the potential of FMSY ranges to combine long-term single-stock targets with flexible, short-term, mixed-fisheries management requirements applied to the main North Sea demersal stocks. It is shown that sustained fishing at the upper bound of the range may lead to unacceptable risks when technical interactions occur. An objective method is suggested that provides an optimal set of fishing mortality within the range, minimizing the risk of total allowable catch mismatches among stocks captured within mixed fisheries, and addressing explicitly the trade-offs between the most and least productive stocks.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Ulrich, C (Reprint Author), Tech Univ Denmark, DTU Aqua Natl Inst Aquat Resources, Charlottenlund Castle,Jaegersborg 1, DK-2920 Charlottenlund, Denmark.

Biological evidence of population mixing}}, Journal = {{JOURNAL OF SEA RESEARCH}}, Year = {{2017}}, Volume = {{120}}, Pages = {{13-23}}, Month = {{FEB}}, Abstract = {{A multi-disciplinary study was conducted to clarify stock identity and connectivity patterns in the populations of European plaice (Pleuronectes platessa) in the Skagerrak-Kattegat transition area between the Eastern North Sea and the Baltic Sea. Five independent biological studies Were carried out in parallel. Genetic markers suggested the existence of different genetic populations in the transition area. Growth backcalculation with otoliths resulted in significant although limited differences in growth rates between North Sea and Skagerrak, indicating weak differentiation or important mixing. Hydrogeographical drift modelling suggested that some North Sea juveniles could settle along the coast line of the Skagerrak and the Kattegat. Tagging data suggested that both juveniles and adult fish from the North Sea perform feeding migrations into Skagerrak in summer/autumn. Finally, survey data suggested that Skagerrak also belongs to the area distribution of North Sea plaice. The outcomes of the individual studies were then combined into an overall synthesis. The existence of some resident components was evidenced, but it was also demonstrated that North Sea plaice migrate for feeding into Skagerrak and might constitute a large share of the catches in this area. The mixing of different populations within a management area has implications for stock assessment and management. Choice must be made to either lump or split the populations, and the feasibility and constraints of both options are discussed. The outcomes of this work have directly influenced the management decisions in 2015. (C) 2016 Elsevier B.V.

In the present work, we focus on the multi-species demersal fisheries of the Aegean Sea (eastern Mediterranean) aiming to study the effects of different management measures on the main commercial stocks, as well as to explore the economic viability of the fisheries depending upon these resources, by means of simulated projections. Utilizing the limited available data, our results demonstrated that, under the current exploitation pattern, the economic viability of the fleets is threatened, particularly if fuel prices increase. Additionally, the biological targets set for the most exploited species, such as hake, will not be met under the current management regime. The projections also showed that the only management scenario under which both resource sustainability and economic viability of the fisheries are ensured is the decrease of fleet capacity in terms of vessel numbers. In this case, however, measures to support the fisheries-dependent communities need to be implemented to prevent the collapse of local economies due to employment decrease. Scenarios assuming selectivity improvements would be also beneficial for the stocks but they showed low economic performance and their application would threaten the viability of the fleets, particularly that of the trawlers.}}, Publisher = {{PUBLIC LIBRARY SCIENCE}}, Address = {{1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Nikolioudakis, N (Reprint Author), Hellen Ctr Marine Res, Inst Marine Biol Resources \& Inland Waters, Iraklion, Greece.

However, this is not the case for assessments conducted in Australia and many other countries. This paper reviews all of the model based stock assessments for Australian fisheries to evaluate how many of these assessments could have been conducted using the publicly-available stock assessment packages used widely in the USA and New Zealand. The 76 model-based assessments reflect 37\% of the 2013 catch recorded in Australia's Status for Key Australian Fish Stocks Reports (or 34\% of the total catch in 2013). All but 18 (or 24 if full rather than approximate age-size structured models need to be used) of the stock assessments could have been conducted using stock assessment packages used in the United States and New Zealand. Adoption and use of packages for more stocks in Australia should increase the likelihood that results are based on correctly-coded models whose estimation performance is widely understood, reduce the time needed to conduct assessments, and speed up the peer-review process. The availability of training, manuals, and example data sets for stock assessment packages should partially address their additional complexity. Additional benefits, in terms of numbers of assessed stocks, could occur if Australian stock assessment scientists develop a forum to collaborate and share methods. These results are applicable to many other jurisdictions that undertake stock assessments.}}, Publisher = {{ELSEVIER SCI LTD}}, Address = {{THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Dichmont, CM (Reprint Author), Cathy Dichmont Consulting, 47 Pioneer Rd, Redlands, Australia.

The validation of model prediction is difficult, however, as fish stocks can rarely be observed and counted. We therefore show how hindcasting and model-free validation can be used to evaluate multiple measures of prediction skill. In a hindcast a model is fitted to the first part of a time series and then projected over the period omitted in the original fit. Prediction skill can then be evaluated by comparing the predictions from the projection with the observations. We show that uncertainty increased when different datasets and hypotheses were considered, especially as time-series of model-derived parameters were sensitive to model assumptions. Using hindcasting and model-free validation to evaluate prediction skill is an objective way to evaluate risk, i.e., to identify the uncertainties that matter. A hindcast is also a pragmatic alternative to hindsight, without the associated risks. While the use of multiple measures helps in evaluating prediction skill and to focus research onto the data and the processes that generated them. (C) 2016 Elsevier B.V.

The ability of MSE to facilitate fisheries management achieving its aims depends on how well uncertainty is represented, and how effectively the results of simulations are summarized and presented to the decision-makers.

Incorporating multiple sources of uncertainty in a stock assessment allows advice to better account for the risks associated with proposed management options, promoting decisions that are more robust to such uncertainty. However, a typical assessment only reports the model fit and variance of estimated parameters, thereby underreporting the overall uncertainty. Additionally, although multiple candidate models may be considered, only one is selected as the `best' result, effectively rejecting the plausible assumptions behind the other models. We present an applied framework to integrate multiple sources of uncertainty in the stock assessment process. The first step is the generation and conditioning of a suite of stock assessment models that contain different assumptions about the stock and the fishery. The second step is the estimation of parameters, including fitting of the stock assessment models. The final step integrates across all of the results to reconcile the multi-model outcome. The framework is flexible enough to be tailored to particular stocks and fisheries and can draw on information from multiple sources to implement a broad variety of assumptions, making it applicable to stocks with varying levels of data availability The Iberian hake stock in International Council for the Exploration of the Sea (ICES) Divisions VIIIc and IXa is used to demonstrate the framework, starting from length-based stock and indices data. Process and model uncertainty are considered through the growth, natural mortality, fishing mortality, survey catchability and stock-recruitment relationship. Estimation uncertainty is included as part of the fitting process. Simple model averaging is used to integrate across the results and produce a single assessment that considers the multiple sources of uncertainty.}}, Publisher = {{PUBLIC LIBRARY SCIENCE}}, Address = {{1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Scott, F (Reprint Author), European Commiss, Joint Res Ctr, Inst Protect \& Secur Citizen, Maritime Affairs Unit, Via Enrico Fermi 2749, I-21027 Ispra, VA, Italy.

Identifying, quantifying, and communicating this uncertainty is key to both evaluating the risk associated with a projection and building confidence in its robustness. We review how uncertainties in such projections are handled in marine science. We employ an approach developed in climate modelling by breaking uncertainty down into (i) structural (model) uncertainty, (ii) initialization and internal variability uncertainty, (iii) parametric uncertainty, and (iv) scenario uncertainty. For each uncertainty type, we then examine the current state-of-the-art in assessing and quantifying its relative importance. We consider whether the marine scientific community has addressed these types of uncertainty sufficiently and highlight the opportunities and challenges associated with doing a better job. We find that even within a relatively small field such as marine science, there are substantial differences between subdisciplines in the degree of attention given to each type of uncertainty. We find that initialization uncertainty is rarely treated explicitly and reducing this type of uncertainty may deliver gains on the seasonal-to-decadal time-scale. Weconclude that all parts of marine science could benefit from a greater exchange of ideas, particularly concerning such a universal problem such as the treatment of uncertainty. Finally, marine science should strive to reach the point where scenario uncertainty is the dominant uncertainty in our projections.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article; Proceedings Paper}}, Language = {{English}}, Affiliation = {{Payne, MR (Reprint Author), Tech Univ Denmark, Natl Inst Aquat Resources DTU Aqua, Ctr Ocean Life, DK-2920 Charlottenlund, Denmark.

Among them, ecosystem-and fisheries-based models are critical to quantitatively predict the consequences of future scenarios by integrating available knowledge about the ecosystem across different scales. Despite increasing development of these complex system models in the last decades, their operational use is still currently limited in Europe. Many guidelines are already available to help the development of complex system models for advice yet they are often ignored. We identified three main impediments to the use of complex system models for decision support: (1) their very complexity which is a source of uncertainty; (2) their lack of credibility, (3) and the challenge of communicating/transferring complex results to decision makers not accustomed to deal with multivariate uncertain results. In this paper, we illustrate these somehow theoretical ``best practices{''} with tangible successful examples, which can help the transfer of complex system models from academic science to operational advice. We first focus on handling uncertainty by optimizing model complexity with regards to management objectives and technical issues. We then list up methods, such as transparent documentation and performance evaluation, to increase confidence in complex system models. Finally, we review how and where complex system models could fit within existing institutional and legal settings of the current European fisheries decision framework. We highlight where changes are required to allow for the operational use of complex system models. All methods and approaches proposed are illustrated with successful examples from fisheries science or other disciplines. This paper demonstrates that all relevant ingredients are readily available to make complex system models operational for advice.}}, Publisher = {{EDP SCIENCES S A}}, Address = {{17, AVE DU HOGGAR, PA COURTABOEUF, BP 112, F-91944 LES ULIS CEDEX A, FRANCE}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Lehuta, S (Reprint Author), IFREMER, Ecol \& Modeles Halieut, Rue Lile Yeu,BP 2011, F-44311 Nantes 03, France.

Sea surface temperature, intense easterly winds, and discharges from the Guadalquivir River have been identified as key factors determining early life stage mortality in this anchovy stock. We have constructed an environment-based recruitment model that simulates the abundance of juveniles under alternative parameters representing plausible biological hypotheses. We are able to evaluate how modelling environment-based recruitment can affect stock assessment and how responding to environmental information can benefit fishery management to allow greater average catch levels through the application of harvest control rules (HCRs) based on environmental conditions. While the environment-based rules generally increase allowable catch levels the variance in catch levels also increases, detracting from the improved value based only on average yield. In addition to changes in revenue, the probability of stock collapse is also reduced by using environmental factors in HCRs. To assess the value of these management systems we simulate a notional insurance scheme, which applies a value to both average yields and uncertainty. The value of the information-driven rules can be determined by comparing the relevant premiums payable for equal levels of insurance cover on revenue within each specific management regime. We demonstrate the net value of incorporating environmental factors in the management of anchovies in the Gulf of Cadiz despite the increased variability in revenue. This could be an effective method to describe outcomes for both commercial fisheries and ecosystem management policies, and as a guide to management of other species whose dynamics are predictable based on in-season observations.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Rincon, MM (Reprint Author), Invest Cient ICMAN CSIC, Dept Coastal Ecol \& Management, Inst Ciencias Marinas Andalucia, Consejo Super, Cadiz 11510, Spain.

As for (i), in 45\% of the examined stocks, the official value for SSBpa was below the consensus estimates determined from three different methods. With respect to (ii), the official estimates of F-msy exceeded natural mortality M in 76\% of the stocks, although M is widely regarded as natural upper limit for F-msy. And regarding (iii), the age at first capture was below the age at maturity in 74\% of the stocks. No official estimates of the stock size (SSBmsy) that can produce the maximum sustainable yield (MSY) are available for the north-east Atlantic. An analysis of stocks from other areas confirmed that twice SSBpa provides a reasonable preliminary estimate. Comparing stock sizes in 2013 against this proxy showed that 88\% were below the level that can produce MSY. Also, 52\% of the stocks were outside of safe biological limits, and 12\% were severely depleted. Fishing mortality in 2013 exceeded natural mortality in 73\% of the stocks, including those that were severely depleted.

Assessments of stock status for different species and exploitation states were presented to workshop participants via alternative user interfaces of the same model. Participants then decided how to manage these fisheries using various management controls, including size and bag limits and temporal and spatial closures. The management decisions made by participants for a range of different scenarios were subjected to multivariate analyses. When the initial level of exploitation of a stock was high, participants typically made stronger and more varied management decisions using a wider range of controls than when exploitation was less. Although these decisions led to substantial reductions in fishing mortality, stock status outcomes were more varied and less optimal than those observed for scenarios of low and moderate levels of initial exploitation. The trends in decisions made by workshop participants probably reflect those that often occur for real-life fisheries, in that as fishing pressure increases, management often becomes more complex and thus its overall effectiveness may become less predictable. Unexpectedly, there were no detectable differences between the decisions made by users of alternative interfaces, which varied in the amount and complexity of stock assessment outputs provided, indicating that the simpler interfaces were as effective as more complex interfaces in communicating stock status information. This study demonstrates the value of scenariotesting experiments for understanding decision making in fisheries management and for assessing whether stock assessment information is conveyed to fishery stakeholders in ways that can be readily understood.}}, Publisher = {{TAYLOR \& FRANCIS INC}}, Address = {{530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Fisher, EA (Reprint Author), Murdoch Univ, Ctr Fish \& Fisheries Res, South St, Murdoch, WA 6150, Australia.

Pearson correlations and robust dynamic factor analysis (DFA) were applied to quantify the connections between isheries and environmental parameters. Variations and trends in ishery series were best explained by changes in near-bottom temperature and salinity, which are an appropriate proxy for tracking changes in water mass dynamics and hydrographic conditions in the basin. A prolonged period of decreasing sardine population was characterized by low oxygen availability and environmental conditions in the deep Adriatic waters and was triggered by an extraordinary basin-wide event called the Eastern Mediterranean Transient.

Information on life history traits may also be available or borrowed from similar species/stocks. In this work we present three harvest control rules (HCRs), driven by indicators derived from key monitoring data. These were tested through simulation using two exploitation scenarios (development and over-exploitation) applied to 50 stocks (pelagic, demersal, deep sea species and Nephrops). We examine the performance of the HCRs to deliver catch-based advice that is risk adverse and drives stocks to MSY. The HCR with a biomass index-adjusted status quo catch, used to provide catch-based advice for several European data-limited stocks, showed the poorest performance, keeping the biomass at low or very low levels. The HCRs that adjust the status quo catch based on the variability of the biomass index time series was able to drive most of the stocks to MSY, showing low to moderate biological risk. The recovery of biomass required asymmetric confidence intervals for the biomass index and larger decreases in status quo catch than increases. The HCR based on length reference points as proxies for the F-SQ/F-msy ratio was able to reverse the decreasing trend in biomass but with levels of catch below MSY. This HCR did not prevent some of the stocks declining when subject to over-exploitation. For data-limited stocks, the empirical HCRs tested in this work can provide the basis for catch advice. Nevertheless, applications to real life cases require simulation testing to be carried out to tune the HCRs. Our approach to simulation testing can be used for such analysis. (C) 2014 Elsevier B.V.

The software `MSE Tool' is not intended to produce definitive real-world advice but provides a test-bed for managers to interactively design strategies and explore the complexities inherent to water quality management using a simple, yet effective, user interface. MSE Tool has been used in a pilot application that simulated the effects of management strategies applied in catchments and their effects on riverine, estuarine and marine water quality in South East Queensland, Australia.

The lack of data on age-composition, missing catch data and species identification problems for some species, lack of fishery-independent index data, as well as environmental influences on population dynamics is compounded by the international nature of how fisheries for billfishes are assessed and managed. This paper overviews the most recent assessments conducted for 20 stocks of billfishes in the Indian, Atlantic and Pacific Oceans, and how management advice is provided for these stocks. Assessments for billfishes are conducted using a wide range of techniques, ranging from catch-only methods which infer stock status based primarily on the prior distributions assumed for the parameters of a population dynamics model, to statistical catch-at-age analyses that integrate a wide range of data types. Key recommendations arising from this review include that age-structured stock assessments should be based on models that allow sex-structure to be represented, a full accounting for uncertainty requires adequately representing uncertainty regarding growth rates, natural mortality, the form and parameters of the stock recruitment relationship, and how data are weighted, and that if biomass dynamics models are to be applied, they should be based on Bayesian state-space formulations rather than observation or process error estimators because such formulations are better able to represent uncertainty.

More energy-efficient fisheries are also likely to alter existing fishing patterns, which already vary from fishery to fishery and from vessel to vessel. The impact assessment of new spatial plans involving fisheries should be based on quantitative bioeconomic analyses that take into account individual vessel decisions, and trade-offs in cross-sector conflicting interests. We use a vessel-oriented decision-support tool (the DISPLACE model) to combine stochastic variations in spatial fishing activities with harvested resource dynamics in scenario projections. The assessment computes economic and stock status indicators by modelling the activity of Danish, Swedish, and German vessels (> 12 m) in the international western Baltic Sea commercial fishery, together with the underlying size-based distribution dynamics of the main fishery resources of sprat, herring, and cod. The outcomes of alternative scenarios for spatial effort displacement are exemplified by evaluating the fishers's abilities to adapt to spatial plans under various constraints. Interlinked spatial, technical, and biological dynamics of vessels and stocks in the scenarios result in stable profits, which compensate for the additional costs from effort displacement and release pressure on the fish stocks. The effort is further redirected away from sensitive benthic habitats, enhancing the ecological positive effects. The energy efficiency of some of the vessels, however, is strongly reduced with the new zonation, and some of the vessels suffer decreased profits. The DISPLACE model serves as a spatially explicit bioeconomic benchmark tool for management strategy evaluations for capturing tactical decision-making in reaction to MSP.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Bastardie, F (Reprint Author), Tech Univ Denmark, Sect Ecosyst Based Marine Management, Inst Aquat Resources, DK-2920 Charlottenlund, Denmark.

Historically, this role has been fulfilled with low-tech conventional tags, but the relatively recent and rapid development of electronic tags has dramatically increased the potential to collect more high quality data. Stock assessment models have also been evolving in power and complexity recently, with the ability to integrate multiple data sources into unified spatially explicit frameworks. However, electronic tag technologies and stock assessment models have developed largely independently, and frameworks for incorporating these valuable data in contemporary stock assessments are nascent, at best. Movement dynamics of large pelagic species have been problematic to resolve in modern assessments, and electronic tags offer new opportunities to resolve some of these issues. Pragmatic ways of modeling movement are often not obvious, and basic research into discrete and continuous processes, for example, is ongoing. Experimental design of electronic tagging research has been driven mostly by ecological and biological questions, rather than optimized for stock assessment, and this is probably a complicating factor in integration of the data into assessment models. A holistic overview of the current state of assessment models, electronic tag technologies, and experimental design is provided here, with the aim to provide insight into how stock assessment and electronic tagging research can be conducted most effectively together.

We used state-of-the-art knowledge to develop a user-friendly simulation software allowing users to evaluate if current management policies meet the conservation target and evaluate the expected performances (spawner escapement and fishing yield) of alternative management scenarios. The software relies upon a demographic model explicitly accounting for the most relevant features of eel demography and has default settings for specific geographical areas and water systems. We demonstrate the software by exploring a variety of management plans in three European water systems. (C) 2014 Elsevier Ltd.

Often, management of these stocks is based on the results of analytical stock assessments. Accurate catch data, which can be attributed to a specific population unit and reflects the population structure, are needed for these approaches. Often though, the quality of the catch data is compromised when dealing with a complex population structure where fish of different population units mix in a fishery. The herring population units west of the British Isles are prone to mixing. Here, the inability to perfectly allocate the fish caught to the population unit they originate from, due to classification problems, poses problems for management. These mixing proportions are often unknown; therefore, we use simulation modelling combined with management strategy evaluation to evaluate the role fisheries-independent surveys can play in an assessment to provide unbiased results, irrespective of population unit mixing and classification success. We show that failure to account for mixing is one of the major drivers of biased estimates of population abundance, affecting biomass reference points and MSY targets. When mixing of population units occurs, the role a survey can play to provide unbiased assessment results is limited. Either different assessment models should be employed or stock status should be considered from the survey data alone. In addition, correctly classifying the origin of fish is especially important for those population units that are markedly smaller in size than other units in the population complex. Without high classification success rates, smaller population units are extremely vulnerable to overexploitation.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Hintzen, NT (Reprint Author), IMARES, Inst Marine Resources \& Ecosyst Studies, POB 68, NL-1970 AB Ijmuiden, Netherlands.

The exercise was made up of two steps applied to datasets from 14 representative fish stocks from around the world. Step 1 involved applying stock assessments to datasets with varying degrees of effort dedicated to optimizing fit. Step 2 was applied to a subset of the stocks and involved characteristics of given model fits being used to generate pseudo-data with error. These pseudo-data were then provided to assessment modellers and fits to the pseudo-data provided consistency checks within (self-tests) and among (cross-tests) assessment models. Although trends in biomass were often similar across models, the scaling of absolute biomass was not consistent across models. Similar types of models tended to perform similarly (e.g. age based or production models). Self-testing and cross-testing of models are a useful diagnostic approach, and suggested that estimates in the most recent years of time-series were the least robust. Results from the simulation exercise provide a basis for guidance on future large-scale simulation experiments and demonstrate the need for strategic investments in the evaluation and development of stock assessment methods.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article; Proceedings Paper}}, Language = {{English}}, Affiliation = {{Deroba, JJ (Reprint Author), NOAA NMFS, 166 Water St, Woods Hole, MA 02543 USA.

However, the development of appropriate management simulation and assessment models has lagged behind the availability of these new data. This paper presents an accessible spatio-temporal simulation framework (Honeycomb) which features a weekly time-step, multiple stocks and vessels, and economic decision rules and applies this to a case study of a spatial evaluation of a simple closed-area fishery policy. We conclude that the development and utilization of such spatio-temporal simulation models is a key research task for fisheries in which both spatial fisheries data and spatial fisheries management are becoming paramount.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article; Proceedings Paper}}, Language = {{English}}, Affiliation = {{Needle, CL (Reprint Author), Marine Scotland Sci, Marine Lab, Aberdeen AB11 9DB, Scotland.

In addition, rocketing fuel costs and low market prices of traditionally high-value species are challenging the viability of fisheries. Here, based on the numeric results of a simulation model, we conclude that this situation can be remedied by reducing both fishing mortality and fishing costs. According to our model results, fishing effort reductions of 48-71\% would improve the health of fish stocks while increasing the economic profits of Mallorca islands bottom trawl fishery to as much as 1.9 M(sic) (146\% higher than current profits). If all fish stocks were exploited at their MSY (or below) level, the reduction in fishing effort would have to be of 71\% from current values. If equilibrium profits from the fishery were to be maximized (MEY), fishing effort would need to be reduced by 48\%. These results must be taken with caution due the many sources of uncertainty of our analysis. The modeling tools used to estimate these values are conditional to the adequate treatment of two sources of uncertainty that are particularly problematic in Mediterranean fisheries: insufficiently known recruitment variability and lack of periodic evaluations of the state of many species. Our results show that fishing effort reductions would produce economic yield gains after a period of transition. Further studies on the benefits of changing the size-selection pattern of fisheries, on better estimation of stock recruitment relationships and on better quantifications of the contribution of secondary species to these fisheries, are expected to improve the scientific recommendations for Mediterranean demersal fisheries toward sustainability principles.

In the last decade, the fisheries stock assessment modeling framework Stock Synthesis (SS3) has become widely used around the world.

Here, we introduce ss3sim, an R package that facilitates reproducible, flexible, and rapid end-to-end simulation testing with SS3. ss3sim requires an existing SS3 model configuration along with plain-text control files describing alternative population dynamics, fishery properties, sampling scenarios, and assessment approaches. ss3sim then generates an underlying `truth' from a specified operating model, samples from that truth, modifies and runs an estimation model, and synthesizes the results. The simulations can be run in parallel, reducing runtime, and the source code is free to be modified under an open-source MIT license. ss3sim is designed to explore structural differences between the underlying truth and assumptions of an estimation model, or between multiple estimation model configurations. For example, ss3sim can be used to answer questions about model misspecification, retrospective patterns, and the relative importance of different types of fisheries data. We demonstrate the software with an example, discuss how ss3sim complements other simulation software, and outline specific research questions that ss3sim could address.}}, Publisher = {{PUBLIC LIBRARY SCIENCE}}, Address = {{1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Anderson, SC (Reprint Author), Simon Fraser Univ, Dept Biol Sci, Earth Ocean Res Grp, Burnaby, BC V5A 1S6, Canada.

These two fishing methods are fundamentally different and have different economic, environmental, and even social effects. In this paper we present a hybrid-simulation framework to assess the impact of changing the ratio between cod quota allocated to vessels with longlines and vessels with bottom trawls. It makes use of conventional bioeconomic models and discrete event modelling and provides a framework for simulating life cycle assessment (LCA) for a cod fishery. The model consists of two submodels, a system dynamics model describing the biological aspect of the fishery and a discrete event model for fishing activities. The model was run multiple times for different quota allocation scenarios and results are presented where different scenarios are presented in the three dimensions of sustainability: environmental, social, and economic. The optimal allocation strategy depends on weighing the three different factors. The results were encouraging first-steps towards a useful modelling method but the study would benefit greatly from better data on fishing activities.}}, Publisher = {{HINDAWI PUBLISHING CORP}}, Address = {{315 MADISON AVE 3RD FLR, STE 3070, NEW YORK, NY 10017 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Siguroardottir, S (Reprint Author), Univ Iceland, Fac Ind Engn Mech Engn \& Comp Sci, Hjaroarhagi 2-6, IS-107 Reykjavik, Iceland.

This can have an impact on the economic, social and environmental outcomes of fisheries management. Management Strategy Evaluation (MSE) modelling approaches are recognised as the most appropriate method for assessing impacts of management, but these require information as to how fleets may change under different management systems. In this study, we test the applicability of data envelopment analysis (DEA) based performance measures as predictors of how a fishing fleet might change under the introduction of ITQs and also at different levels of quota. In particular, we test the assumption that technical efficiency and capacity utilisation are suitable predictors of which boats are likely to exit the fishery. We also consider scale efficiency as an alternative predictor. We apply the analysis to the Torres Strait tropical rock lobster fishery that is transitioning to an ITQ-based management system for one sector of the fishery. The results indicate that capacity utilisation, technical efficiency and scale efficiency are reasonable indicators of who may remain in the fishery post ITQs. We find that the use of these measures to estimate the impacts of lower quota levels provides consistent fleet size estimates at the aggregate level, but which individual vessels are predicted to exit is dependent on the measure used.

For these three stocks, earlier studies have suggested a high correlation between their recruitment and a positive relationship between high temperatures and good recruitment. These hypotheses were revisited using stock assessment and temperature data for the period 1913-present. The cod-haddock and herring-haddock recruitment correlations were both significant and positive in some periods, but became insignificant towards the end of the period. Cod and herring recruitment was not significantly correlated. Recruitment variability was found to decline towards the end of the period for all species, in particular for cod. For all three stocks there is a significant positive relationship between recruitment and temperature; this relationship is strongest for haddock and weakest for herring. Recruitment was found to be low at low temperatures and variable at medium/high temperatures during the first year of life for all three species. Temperature during the first winter of life correlates positively with haddock and cod recruitment residuals. This correlation is weakened towards the end of the period for cod, but stays high for haddock.

This implies slow recovery from low biomass levels and it is, therefore, important to manage these stocks correctly to avoid overfishing. However, these stocks are generally data poor, which it makes difficult to apply quantitative assessment models on which to base their management. The management strategy evaluation (MSE) approach consists in evaluating the performance of management strategies by simulation before their implementation. In the evaluation, the main sources of uncertainty in a fishery system and its management process should be taken into account in order to find robust management strategies. Thus, the MSE approach is relevant to the management of data-poor stocks. We used the FLBEIA software, an FLR library coded in the R statistical language, to conduct a bio-economic impact assessment of fisheries management strategies. We evaluated the performance of several management strategies in three different deepwater case studies using the MSE approach: beaked redfish (Sebastes mentella) in the Norwegian Sea, blackspot seabream (Pagellus bogaraveo) in the Strait of Gibraltar, and French mixed deepwater fisheries in the North East Atlantic. In conclusion, we found that the S. mentella stock is very sensitive to the stock recruitment relationship chosen. For P. bogaraveo, simulations showed that the present constant catch management is as good as more sophisticated strategies.

Spatial management is used extensively in natural resource management to address sustainability and biodiversity issues, for example through declaration of terrestrial National Parks and marine protected areas (MPAs). 2. Spatial management is used also to optimize yields or protect key parts of the life cycle of species that are utilized (hunted, farmed or fished), for example through rotational harvesting. 3. To evaluate the effectiveness of marine spatial closures with conflicting fisheries and conservation objectives, a series of marine fisheries closures are here analysed using an integrative modelling tool known as management strategy evaluation (MSE). 4. This modelling framework combines a food web model of a tropical ecosystem fished by a prawn (shrimp) fishery that emulates the resource being managed, together with the present management system and risk-based tools of fishing the prawn species at maximum economic yield. 5. A series of spatial closures are designed and tested with the aim of investigating trade-offs among biodiversity (MPA), benthic impacts, ecosystem function, key species at risk to fishing, economic and sustainability objectives. 6. Synthesis and applications. This paper illustrates that existing tools often available in actively managed fisheries can be linked together into an effective management strategy evaluation framework. Spatial closures tended to succeed with respect to their specific design objective, but this benefit did not necessarily flow to other broad-scale objectives. This demonstrates that there is no single management tool which satisfies all objectives, and that a suite of management tools is needed.}}, Publisher = {{WILEY-BLACKWELL}}, Address = {{111 RIVER ST, HOBOKEN 07030-5774, NJ USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Dichmont, CM (Reprint Author), CSIRO Wealth Oceans Flagship, Ecosci Precinct, 41 Boggo Rd, Dutton Pk, Qld, Australia.

The main focus was on blue ling (Molva dypterygia). For that species, both data-rich and data-limited HCRs were tested, while catch per unit effort (CPUE) was used either to tune stock assessments, or to directly trigger management action. There were only limited differences between the performances of both HCRs when blue ling biomass was initialized at the current level, but blue ling recovered more quickly with the data-rich HCR when its initial biomass was severely depleted. Both types of HCR lead, on average, to a long-term recovery of both blue ling and saithe (Pollachius virens) stocks, and some increase in overall profit. However, that improvement is not sufficient to guarantee sustainable exploitation with a high probability. Blue ling CPUE did not always adequately reflect trends in biomass, which mainly resulted from fleet dynamics, possibly in combination with density-dependence.

The voluntary Code of Conduct on Responsible Fishing and the United Nations Fish Stocks Agreement provide the formal basis for the Precautionary Approach to fisheries management. Some tuna Regional Fisheries Management Organisations such as the WCPFC and IATTC make explicit mention of these codes in their conventions, whilst others, whose conventions do not explicitly address the Precautionary Approach, are searching for ways in which to take these codes into consideration. In practical terms, the scientific obligations to Precautionary Approaches are to determine the status of the stock(s) relative to limit and target reference points, to predict outcomes of management alternatives for reaching the targets and avoiding the limits, and to characterise the uncertainty in both cases. A convenient framework to conduct management evaluations is through the use of harvest control rules, for which managers agree on specific management actions under their control which are evoked according to levels of stock status relative to predefined reference points. These pre-agreed management actions are then simulated for a range of scenarios. This paper presents the ways in which tuna RFMOs are currently incorporating the precautionary approach in their fisheries management as well as suggestions for possible best practice.

A stochastic viability approach is proposed to address the trade-offs associated with balancing ecological, economic and social objectives in regulating mixed fisheries, taking into account the complexity and uncertainty of the dynamic interactions which characterize such fisheries. We focus on the demersal fishery in the Bay of Biscay and more specifically on the fleets harvesting Norway Lobster (Nephrops norvegicus), Hake (Merluccius merluccius) and Sole (Solea solea). A bio-economic multi-species and multi-fleet model with technical interactions is developed to examine the trade-offs between preserving Spawning Stock Biomass (SSB) of every species and maintaining the economic profitability of the various fishing fleets. Different management strategies are tested and compared. Results suggest that ensuring viability of this demersal fishery requires a significant decrease in fishing capacity as compared to the reference year. The simulations allow comparing the trade-offs associated with different allocations of this decrease across fleets. (C) 2012 Elsevier B.V.

Since the late 1980s. when such approaches were first introduced, there have been substantial developments in this area of science, to the point where the concepts of fleet and m tier now underpin the whole EC Data Collection Framework. However, their implementation in the management system has been slow and difficult, being hampered by a number of intrinsic issues. Mixed fisheries are an ongoing ``governance headache{''} combining management complexity, scientific uncertainty and political sensitivity. This paper summarises the current state of play for fleet-based approaches in EU fisheries management, and highlights our views on both their potential and the challenges they face in the context of the future CFP. As a convenient layer between the current single-stock level and the level of the individual vessel, fleet/metier- approaches could potentially address a wide range of issues, especially with regards to the policy emphasis on ecosystem-based fisheries management. However, the rigid categorisation they induce may not properly address the flexibility of individual vessels, and should therefore be supplemented by more detailed considerations at the local scale.

In this paper we show why if MSY is used as reference point, optimal management may entail pulse fishing. This means that current management of the European fisheries is based on metrics that may generate solutions that would not be accepted as feasible due to the large social costs implied. We discuss why changes in the metrics used to define the reference point (the logMSY) and/or optimal harvesting control rules that stabilize the employment and the biomass around the optimal stationary values are two possible solutions of this paradox. The European Union should take into account all these considerations for the CFP reform proposals. (C) 2012 Elsevier Ltd.

Reducing the uncertainties around scientific models has long been perceived as the cure of the fisheries management problem. There is however increasing recognition that uncertainty in the numbers will remain. A lack of transparency with respect to these uncertainties can damage the credibility of science. The EU Commission's proposal for a reformed Common Fisheries Policy calls for more self-management for the fishing industry by increasing fishers' involvement in the planning and execution of policies and boosting the role of fishers' organisations. One way of higher transparency and improved participation is to include stakeholders in the modelling process itself. The JAKFISH project (Judgment And Knowledge in Fisheries Involving StakeHolders) invited fisheries stakeholders to participate in the process of framing the management problem, and to give input and evaluate the scientific models that are used to provide fisheries management advice. JAKFISH investigated various tools to assess and communicate uncertainty around fish stock assessments and fisheries management. Here, a synthesis is presented of the participatory work carried out in four European fishery case studies (Western Baltic herring, North Sea Nephrops, Central Baltic Herring and Mediterranean swordfish), focussing on the uncertainty tools used, the stakeholders' responses to these, and the lessons learnt. It is concluded that participatory modelling has the potential to facilitate and structure discussions between scientists and stakeholders about uncertainties and the quality of the knowledge base. It can also contribute to collective learning, increase legitimacy, and advance scientific understanding. However, when approaching real-life situations, modelling should not be seen as the priority objective. Rather, the crucial step in a science-stakeholder collaboration is the joint problem framing in an open, transparent way. (C) 2012 Elsevier Ltd.

Data on effort, landings and socioeconomic parameters were used for coastal and trawl fisheries in the Aegean Sea. Results pointed out the strengths and weaknesses of alternative management strategies from both a biological and socioeconomic perspective. Fcube revealed the importance of effort control in the coastal fisheries that are still managed with no effort restrictions. The present findings, although preliminary, revealed that stringent cuts to effort and catch levels are required if EA management goals are to be met.

Analyses start with standardized data formats for logbook (EFLALO) and VMS (TACSAT), enabling users to conduct a variety of analyses using generic algorithms. Embedded functionality handles erroneous data point detection and removal, m tier identification through the use of clustering techniques, linking logbook and VMS data together in order to distinguish fishing from other activities, provide high-resolution maps of both fishing effort and -landings, interpolate vessel tracks, calculate indicators of fishing impact as listed under the Data Collection Framework at different spatio-temporal scales. Finally data can be transformed into other existing formats, for example to populate regional databases like FishFrame. This paper describes workflow examples of these features while online material allows a head start to perform these analyses. This software incorporates state-of-the art VMS and logbook analysing methods standardizing the process towards obtaining pan-European, or even worldwide indicators of fishing distribution and impact as required for spatial planning.

However, monitoring programs often neglect important sources of error and thus can lead to biased estimates, spurious conclusions and false management actions. One such source of error is `imperfect detectability', i.e. the inability of investigators to detect all individuals or all species in a surveyed area. Although there has been great effort to develop monitoring methods that account for imperfect detectability, the application of such methods in the marine environment is not as apparent as in other systems. Plot sampling is by far the most commonly applied method for biological monitoring in the marine environment, yet it largely ignores detectability issues. However, distance sampling, mark-recapture methods, repeated presence-absence surveys for occupancy estimation, and removal methods do estimate detection probabilities and provide unbiased estimates of state variables. We review these methods and the relevant tools for their application in studies on marine populations and communities, with the aim of assisting marine biologists and managers to understand the limitations and pitfalls associated with some approaches and to select the best available methods for their monitoring needs.}}, Publisher = {{INTER-RESEARCH}}, Address = {{NORDBUNTE 23, D-21385 OLDENDORF LUHE, GERMANY}}, Type = {{Review}}, Language = {{English}}, Affiliation = {{Katsanevakis, S (Reprint Author), HCMR, 46-7 Km Athens Sounio, Anavyssos 19013, Greece.

Moreover, dependent fisheries often develop rapidly, so overexploitation may occur before resource dynamics are quantified sufficiently to assess safe biological limits. It is therefore crucial to employ assessment methods that make the best use of limited data and management procedures that account for large uncertainties. This review provides a critical synthesis of assessment and management approaches for deepwater fisheries. Given limitations in the data, it is clear that assessments are likely to benefit from the application of derived relationships between life-history characteristics and the sharing of this and other information across stocks. It is important that uncertainty in assessment results is represented adequately, and management methods must in turn ensure that decision mechanisms are robust to an incomplete picture of resource dynamics. This requires construction and testing of harvest control rules within a simulation framework. Harvest control rules themselves, however, need not be complicated, and simple empirical approaches can be adequate for situations in which only relative changes in biomass can be discerned from the data. Development and testing of these control rules is likely to prove a productive area of future research.}}, Publisher = {{TAYLOR \& FRANCIS INC}}, Address = {{530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Edwards, CTT (Reprint Author), Imperial Coll London, Div Biol, Silwood Pk, Ascot SL5 7PY, Berks, England.

The stock was dominated by age groups 1 and 2, not exceeding age group 4. The sardine stock in this area was assessed through an Integrated Catch-at-Age model which implements a separable Virtual Population Analysis on catch-at-age data with weighted tuning indices. Sardine landings data derived from the commercial purse seine fishery over the period 2000-2008 were combined with the age structure of the stock as resulting from fisheries' independent acoustic surveys. Sensitivity analysis of the impact of natural mortality values on stock assessment results was applied. Additionally forecast of the sardine population parameters and catches under different exploitation scenarios was implemented on a medium term basis. Results indicated that the North Aegean Sea sardine stock is considered fully exploited, with the fishery operating close to, but over the empirical exploitation level for sustainability. Finally, the status of the sardine stock in the North Aegean Sea is discussed in relation to the sardine stocks from the western and the central Mediterranean basin.}}, Publisher = {{NATL CENTRE MARINE RESEARCH}}, Address = {{AGHIOS KOSMAS, HELLINIKON, GR-16-604, GREECE}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Giannoulaki, M (Reprint Author), Hellen Ctr Marine Res, Inst Marine Biol Resources, POB 2214, Iraklion 71003, Greece.

The work investigated whether the variation in fishing power could be the result of the technical characteristics of a vessel and/or its gear or whether it is a reflection of inter-vessel differences not accounted for by the technical attributes. These inter-vessel differences could be indicative of a skipper/crew experience effect. To improve understanding of the relationships, landings per unit effort (lpue) from logbooks and technical information on vessels and gears (collected during interviews) were used to identify variables that explained variations in fishing power. The analysis was undertaken by applying a combination of generalized additive models and generalized linear models to data from several European fleets. The study highlights the fact that taking into account information that is not routinely collected, e. g. length of headline, weight of otter boards, or type of groundrope, will significantly improve the modelled relationships between lpue and the variables that measure relative fishing power.

Moreover, the influence of environmental variability on potential recruitment success may be discerned from model hindcasts. Based on case studies, biophysical modelling results are shown to be capable of shedding light on whether stock management frameworks need re-evaluation.

As such, the total allowable catch (TAC) of one species may be exhausted before the TAC of another, leading to catches of valuable fish that cannot be landed legally. This important issue is, however, usually not quantified and not accounted for in traditional management advice. A simple approach using traditional catch and effort information was developed, estimating catch potentials for distinct fleets (groups of vessels) and metiers (type of activity), and hence quantifying the risks of over-and underquota utilization for the various stocks. This method, named Fcube (Fleet and Fisheries Forecast), was applied successfully to international demersal fisheries in the North Sea and shaped into the advice framework. The substantial overquota catches of North Sea cod likely under the current fisheries regimes are quantified, and it is estimated that the single-species management targets for North Sea cod cannot be achieved unless substantial reductions in TACs of all other stocks and corresponding effort reductions are applied.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Ulrich, C (Reprint Author), Tech Univ Denmark, Natl Inst Aquat Resources DTU Aqua, DK-2920 Charlottenlund, Denmark.

Next, we tested these time-series as new explanatory variables in an existing temperature-dependent recruitment function and applied these recruitment predictions in an age-structured ecological economic optimization model, maximizing for profit. Economic optimal solutions depended upon variability in temperature trajectories. Under climate-change scenarios, mean optimal fishing mortality and related yields and profits increased. The extent of the increase was limited by the general shape of the stock recruitment model and the assumption of density-dependence. This highlights the need to formulate better environmentally sensitive stock recruitment models.

After that, in 2007 and once this objective was on the track of being fulfilled a long term management plan was proposed. This plan has to be congruent with the maximum sustainable yield policy as well as producing stable yields and population levels. Thus, in that year, a bioeconomic impact assessment of long-term management plans for this stock was carried out. However the biological and economic assessments were not integrated and not fully congruent. On the basis of this assessment additional questions relating to the combination of harvest control rules with technical measures were raised by the managers and stakeholders. Here, the model used in the biological assessment is extended in order to integrate the economic part and to shed light on the effect of technical measures at stock and fleet level. Two scenarios are presented: a `base case', where the model is parameterized from historical observations; and an `alternative case' where an increase in the mesh size of some trawlers is simulated. In both scenarios the probability of falling below limit reference points is above 0, contrary to the result obtained in 2007. However, the relative trends of the median of population indicators are similar. While the biological performance of the base and alternative scenarios is also similar the trawlers are highly penalized when their mesh size is increased and the overall economic profit is lower. Furthermore, two fleets gain and the rest remain the same with the increase in the mesh size of trawlers. (C) 2011 Elsevier B.V.

Managers of federal fisheries in the eastern Bering Sea, USA, have adopted an EAM. The tools used to support EAM in the eastern Bering Sea serve as a guide to what types of models could be used elsewhere. A review of the role of natural science in the implementation of EAM shows that scientific advice enters into decision-making at a variety of steps. Single-species stock assessment and projection models are the most commonly used tools employed to inform managers. Comprehensive assessments (e.g. management strategy evaluation) are emerging as a new and potentially valuable analysis technique for use in assessing trade-offs of different strategic alternatives. In the case of management in the eastern Bering Sea, end-to-end models and coupled biophysical models have been used primarily to advance scientific understanding, but have not been applied in a management context. This review highlights that implementation of an EAM in a management environment such as eastern Bering Sea requires substantial commitments to the collection and analysis of data and support for a group of analysts with interdisciplinary training in population dynamics, oceanography and ecology. This review supports the growing recognition that a diverse suite of modelling tools is needed to address tactical and strategic management issues germane to the adoption of the ecosystem approach to fisheries management.}}, Publisher = {{WILEY-BLACKWELL}}, Address = {{COMMERCE PLACE, 350 MAIN ST, MALDEN 02148, MA USA}}, Type = {{Review}}, Language = {{English}}, Affiliation = {{Hollowed, AB (Reprint Author), Alaska Fisheries Sci Ctr, 7600 Sand Point Way NE, Seattle, WA 98115 USA.

The assessment procedures considered were: the eXtended Survivors Analysis (XSA), the Schaefer production model, and the difference model. Four HCRs were considered: first, fishing mortality was set on the basis of the relationship between the current biomass and a reference biomass; second, fishing mortality was gradually reduced (or increased) until it reached a required target; and the third and the fourth HCRs were similar to the first and second but with imposed TAC constraints. The stock that was generated in the operating model (OM) resembled the eastern Baltic cod stock. For the XSA assessment, two options were used: XSA with default shrinkage of terminal fishing mortality to the average of the estimates, and XSA with low shrinkage. The simulations showed that for stock assessment, the XSA models performed much better than the difference and Schaefer models.

MSY became a strategic goal for the management of Europe's fisheries following the resolution of the World Summit on Sustainable Development in 2002 to restore or maintain fish stocks to MSY levels by 2015. Calculation of MSY requires information on the rate at which biomass increases through growth and reproduction and the rate at which it decreases through natural mortality and fishing. Population-selection, which measures the age-specific rates of fishing mortality, is a key component for the calculation of yield as a function of fishing mortality and MSY, yet selection rarely features in either management advice or sensitivity analyses. Effective management of selection can potentially lead to increases in long-term yield, but before taking action managers need to understand what long-term increases are possible. Using a hypothetical stock, equilibrium yield curves were calculated for three scenarios in which the shape of the population-selection curve varied. The results illustrate the potential extent of variation in MSY and the corresponding fishing mortality required to achieve it (F(MSY)) that may result solely due to changes in population selectivity. They show that relatively subtle changes in selection can produce substantial differences in MSY and F(MSY). The results are discussed with specific reference to the development of long-term management targets and the mechanisms by which managers might try to influence population-selection.

Several stock-specific studies have suggested that changes in the age structure might have consequences for subsequent recruitment, but the evidence is not universal. To investigate how common such effects are among 39 Northeast Atlantic fish stocks, relationships were tested between age structure (spawner mean age, age diversity, and proportion of recruit spawners) and recruitment (number of recruits, sensitivity to environment, and recruitment variability). Significant correlations in the expected direction were observed for a few stocks, but not for the majority; significant correlations in the opposite direction were also found. Meta-analyses combining the stock-level tests revealed that none of the effects were significant overall. However, effects were significant for some species (cod, haddock, and plaice) and indices. The low variability in the age structure might explain the absence of significant effects for individual stocks. Other reasons could be the absence of a biological basis (reproductive characteristics not dependent on age) or the stronger influence of environmental variability than of age structure on recruitment.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Brunel, T (Reprint Author), Wageningen IMARES, POB 68, NL-1970 AB Ijmuiden, Netherlands.

Applying single-species assessment and quotas in multispecies fisheries can lead to overfishing or quota underutilization, because advice can be conflicting when different stocks are caught within the same fishery. During the past decade, increased focus on this issue has resulted in the development of management tools based on fleets, fisheries, and areas, rather than on unit fish stocks. A natural consequence of this has been to consider effort rather than quota management, a final effort decision being based on fleet-harvest potential and fish-stock-preservation considerations. Effort allocation between fleets should not be based on biological considerations alone, but also on the economic behaviour of fishers, because fisheries management has a significant impact on human behaviour as well as on ecosystem development. The FcubEcon management framework for effort allocation between fleets and fisheries is presented, based on the economic optimization of a fishery's earnings while complying with stock-preservation criteria. Through case studies of two European fisheries, it is shown how fishery earnings can be increased significantly by reallocating effort between fisheries in an economically optimal manner, in both effort-management and single-quota management settings.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Hoff, A (Reprint Author), Univ Copenhagen, Inst Food \& Resource Econ, Rolighedsvej 25, DK-1958 Frederiksberg C, Denmark.

Stochastic bioeconomic modelling of alternative management measures for anchovy in the Mediterranean Sea. - ICES Journal of Marine Science, 67: 1291-1300. The purse-seine fishery for anchovy in the Aegean Sea consists of two main fleet segments (12-24 and 24-40 m vessels); this paper investigates economically and biologically preferable effort and capacity scenarios for the fishery. Attention is paid to a bioeconomic analysis of fleets composed of segments with varying levels of efficiency ( in terms of catch rate) and costs ( fixed and variable) and the role this might play in optimal effort allocation at a fleet level. An age-structured stochastic bioeconomic operating model for Aegean anchovy (Engraulis encrasicolus) is constructed. It attempts to account robustly for the multiple uncertainties in the system, including (i) the effort-fishing mortality relationship, (ii) the selectivity, and (iii) the stock-recruit dynamics of the population. A method is proposed for determining the economically optimal level of long-term effort in a fishery such as this, with similar characteristics in terms of stock dynamics, fishery, and markets. Lower values of effort and capacity are predicted to yield greater future profit when viewing the fleet in its entirety, but even lower values may be advisable to maintain the long-term biological integrity of the stock. The results may prove useful in balancing the productivity of the stock with the harvesting capacity of the fleet, while managing to ensure the long-term profitability of the fleet along with the sustainability of the resource.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Maravelias, CD (Reprint Author), HCMR, 46-7 Km Athens Sounio,POB 712, Anavissos 19013, Attica, Greece.

They are effective for conservation in tropical and subtropical areas (mainly coral and rocky reefs), but it is debated whether they are useful in the management of migratory fish stocks in open temperate regions. World War II created a large marine area within which commercial fishing was prevented for 6 years. Here we analyse scientific trawl data for three important North Sea gadoids, collected between 1928 and 1958. Using statistical models to summarise the data, we demonstrate the potential of MPAs for expediting the recovery of over-exploited fisheries in open temperate regions. Our age-structured data and population models suggest that wild fish stocks will respond rapidly and positively to reductions in harvesting rates and that the numbers of older fish in a population will react before, and in much greater proportion, than their younger counterparts in a kind of Mexican wave. Our analyses demonstrate both the overall increase in survival due to the lack of harvesting in the War and the form of the age-dependent wave in numbers. We conclude that large closed areas can be very useful in the conservation of migratory species from temperate areas and that older fish benefit fastest and in greater proportion. Importantly, any rise in spawning stock biomass may also not immediately result in better recruitment, which can respond more slowly and hence take longer to contribute to higher future harvestable biomass levels.}}, Publisher = {{SPRINGER}}, Address = {{233 SPRING ST, NEW YORK, NY 10013 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Beare, D (Reprint Author), Wageningen IMARES, Haringkade 1,Postbus 68, NL-1970 AB Ijmuiden, Netherlands.

However, most of the potential interest of tracking data depends on the ability to develop suitable modelling strategies to analyze trajectories from discrete recorded positions. A serious modelling challenge is to infer the evolution of the true position and the associated spatio-temporal distribution of behavioural states using discrete, error-prone and incomplete observations. In this paper, a Bayesian Hierarchical Model (HBM) using Hidden Markov Process (HMP) is proposed as a template for analyzing fishing boats trajectories based on data available from satellite-based vessel monitoring systems (VMS). The analysis seeks to enhance the definition of the fishing pressure exerted on fish stocks, by discriminating between the different behavioural states of a fishing trip, and also by quantifying the relative importance of each of these states during a fishing trip. The HBM approach is tested to analyse the behaviour of pelagic trawlers in the Bay of Biscay. A hidden Markov chain with a regular discrete time step is used to model transitions between successive behavioural states (e.g., fishing, steaming, stopping (at Port or at sea)) of each vessel. The parameters of the movement process (speed and turning angles) are defined conditionally upon the behavioural states. Bayesian methods are used to integrate the available data (typically VMS position recorded at discrete time) and to draw inferences on any unknown parameters of the model. The model is first tested on simulated data with different parameters structures. Results provide insights on the potential of HBM with HMP to analyze VMS data. They show that if VMS positions are recorded synchronously with the instants at which the process switch from one behavioural state to another, the estimation method provides unbiased and precise inferences on behavioural states and on associated movement parameters. However, if the observations are not gathered with a sufficiently high frequency, the performance of the estimation method could be drastically impacted when the discrete observations are not synchronous with the switching instants. The model is then applied to real pathways to estimate variables of interest such as the number of operations per trip, time and distance spent fishing or travelling. (C) 2010 Elsevier B.V.

For instance, for the Faroe Plateau mixed demersal fisheries, the TAC system failed to achieve the objective of an average annual fishing mortality of 0.45 for the three gadoid stocks cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and saithe (Pollachius virens). Therefore, in 1996, an effort-regulation system with individual transferable effort quotas was introduced to manage the fisheries. Experience has shown that effort management without additional stock-specific measures may not be appropriate for such fisheries. A management strategy evaluation model was developed to compare an effort-management system based on the Faroese example with a TAC system as currently applied in EU fisheries. Results show that when stocks are considered in isolation, a total allowable effort system does not necessarily perform better than a TAC one. It depends on stock status and dynamics, the level of uncertainty, and the reactivity of the system to changes in scientific advice. When the stocks are considered together in mixed fisheries, effort management seems, however, to be appropriate, and interannual flexibility of the system appears to be the best compromise between short- and long-term objectives, as well as between biological sustainability and economic return.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Ulrich, C (Reprint Author), Tech Univ Denmark, Natl Inst Aquat Resources, DTU Aqua, DK-2920 Charlottenlund, Denmark.

As fisheries are complex systems, fisheries simulation models are often complex, with many uncertain parameters. Here, the methodology is provided to deliver fishery diagnostics within an uncertainty context using a complex simulation tool. A sensitivity analysis of the model is performed on model outputs using partial least-squares to identify the most sensitive parameters. The impact of several management measures is then simulated using a statistical simulation design taking into account the uncertainty of the selected sensitive parameters. This approach was applied to the Bay of Biscay anchovy stock using the ISIS-Fish (Integration of Spatial Information for Simulation of Fisheries) model to assess the impact of imposing marine protected areas (MPAs) conditionally on parameter uncertainty. The diagnostic appeared to be highly sensitive to the mortality of larvae and juveniles, growth, and reproduction. The uncertainty of the values of these parameters did not permit any of the simulated MPA designs to be proposed. However, according to anchovy catch and biomass, the simulations allowed the low impact of closure duration to be shown and underscored the utility of protecting such key processes as spawning.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Lehuta, S (Reprint Author), IFREMER, Rue Ile Yeu,BP 21105, F-44311 Nantes 03, France.

For almost a decade, the Commission for the Conservation of Southern Bluefin Tuna (CCSBT) struggled to reach agreement on a total allowable catch (TAC) for southern bluefin tuna (SBT) because of stock assessment uncertainties. To address this, in 2002 the CCSBT commenced development of a management procedure (MP), a pre-agreed set of rules to determine how the TAC will be adjusted as new monitoring data become available. The CCSBT Scientific Committee tested various candidate MPs using operating models which simulate fish population and fishery dynamics as well as incorporate process, observation, and model uncertainties. Candidate MPs were evaluated using performance measures related to the following management objectives: maximize catches, avoid stock collapse, and minimize interannual catch variation. Of the MPs explored, some relied solely on empirical data {[}i.e., adjusted TAC based on catch per unit effort (CPUE) trends], whereas others were more complicated, based on population models. In 2005, the CCSBT adopted a model-based MP that realized a moderate catch with low variability and avoided stock collapse. This MP struck a compromise between the risk-prone and risk-averse standpoints of the different stakeholders. However, despite this concerted scientific effort, the MP was not implemented because, shortly after its adoption, it became evident that historical catches may have been substantially underreported. This complication necessitates returning to near the beginning of the development process. MP approaches have various advantages and challenges to be explored further. However, it is essential to lessen human-introduced uncertainty (such as catch misreporting) by enhanced enforcement, and to increase management robustness to biological uncertainties by implementing MPs.}}, Publisher = {{SPRINGER TOKYO}}, Address = {{1-11-11 KUDAN-KITA, CHIYODA-KU, TOKYO, 102-0073, JAPAN}}, Type = {{Review}}, Language = {{English}}, Affiliation = {{Kurota, H (Reprint Author), Fisheries Res Agcy, Natl Res Inst Far Seas Fisheries, 5-7-1 Orido, Shizuoka 4248633, Japan.

We present a full population model of winter skate to better understand the population dynamics of the species and elucidate the mechanisms underlying their increase in abundance in the 1980s. Specifically, we developed four statistical catch-at-age models incorporating length-frequency data with the following model structures: (i) observation error only (base model R1); (ii) observation and recruitment process errors (model R2); (iii) adult migration modeled as a random walk in adult mortality (model R3); and (iv) observation and recruitment process errors and adult migration (model R4). Akaike's information criterion values indicated that models R3 and R4, which both included adult migration, were the most parsimonious models. This finding strongly suggests that the winter skate population increase on Georges Bank in the 1980s was not solely a result of increases in recruitment but likely involved adult migration (i. e., it is an open population).

MSE simulations allow the testing of the robustness of conventional management systems to uncertainties or different hypothesis about underlying population dynamics. For this purpose, four different reproductive potential (RP) indices of increasing biological complexity (i.e. Spawning Stock Biomass (SSB) using constant maturity: SSB(MAT) adding variation on maturity, Female Spawning Biomass-FSB, and Total Egg Production-TEP) were estimated and tested. The inclusion of more biological information affected the perception of the population dynamics, the biological reference points (BRPs) as well as the perception of the stock in relation to those biological reference points. In this study, the probability of a wrong perception, i.e. the ``perceived{''} population is above reference limits while the ``true{''} population is overfished, was 13, 5, 3 and 3\% for the different RP investigated in the time period between 1978 and 2008. This probability was around 0\% in all cases studied for the projected period of 2009-2040. Our results show that (i) when including more information about reproductive biology in the simulation, the number of years below the BRPs are higher in the ``perceived{''} population than in the ``true{''} population, (ii) for the historic period the probability of a wrong perception is diminished when alternative reproductive indices are included when simulating both, `true' and `perceived' populations, and (iii) during the initial years of the projected period, although the perception of the population dynamics in relation to BRP is different between SSB(WG) scenario and alternative RP indices, the outcomes of the management advice of the SSB(WG) are more restrictive because the wrong perception is conservative, i.e. when ``true{''} population is above B(pa) the SSB(WG) is below. Thus, it can be concluded that the MP for European hake is robust to the different hypothesis about alternative RP indices. However, the results of the present study also showed that for the historic period, when the population level was close to BRP level, the perception of the stocks status differs between alternative RP indices. Thus, it would be convenient to include the reproductive biology of the species in the Harvest Control Rules (HCR) and Long Term Management Plan (LTMP) of this stock, especially when the level of the stock is close to BRP level.

Some of their points are sound, such as the need for care in representing uncertainties and for thorough documentation of the process. However, others evidence important misunderstandings. Although the difficulties in estimating tail probabilities and risks, as discussed by Rochet and Rice, are well known, their arguments that Efron's nonparametric bootstrap re-sampling method underestimates the probabilities of low values are flawed. In any case, though, the focus of MSEs is primarily on comparing performance and robustness across alternative management procedures (MPs), rather than on estimating absolute levels of risk. Qualitative methods can augment MSE, but their limitations also need to be recognized. Intelligence certainly needs to play a role in fisheries management, but not at the level of tinkering in the provision of annual advice, which Rochet and Rice apparently advocate, inter alia because this runs the risk of advice following noise rather than signal. Instead, intelligence should come into play in the exercise of oversight through the process of multiannual reviews of MSE and associated MPs.

Using a spatially explicit dynamic-state variable model, the optimal fishing strategy of fishers constrained by annual individual quotas, facing uncertainty in catch rates, is studied. Individual fishers will move away from areas with high catches of the restricted quota species and, depending on the cost of fishing, will stop fishing in certain periods of the year. Individual vessels will discard marketable fish, but only after their individual quota for the species under consideration has been reached. These results are in line with observations on effort allocation and discarding of marketable fish, both over-quota discarding and highgrading, by the Dutch beam-trawl fleet.

The plan combines harvest control rules that set TACs with reductions in direct effort (E) and fishing mortality (F). Performance and robustness of the plan are tested with a management strategy evaluation model (MSE). Stochastic simulations are carried out under different scenarios of recruitment and sources of uncertainties. Under the different magnitudes of errors investigated, the plan in its current design is likely to reach precautionary targets for the Eastern and the Western Baltic cod stocks by 2015. It is, however, more sensitive to implementation errors (e.g. catch misreporting) than to observation errors (e.g. data collection) when the (i) current settings of the ICES single-stock assessment model are maintained. (ii) intended fishing effort reduction is fully complied with, and (iii) biological parameters are assumed constant. For the Eastern Baltic stock, additional sources of uncertainties from fishery adaptation to the plan are tested using a fleet-based and spatially explicit version of the model which leads to higher reductions in F and no significant change in management robustness. The relative difference between both approaches is mainly due to differences in exploitation patterns in catching the same amount of fish. The effort control is demonstrated to be more efficient when supplemented with a TAC and avoids un-intended effects from fishery responses, e.g. spatial effort reallocation. Medium term economic evaluation of fishery performance shows an initial reduction in profit with effort and TAC reductions, but profit is always positive. (C) 2009 Elsevier B.V.

A range of operational management procedures for the case study stocks were designed and evaluated using trends that may be derived from survey indices (spawner biomass, year-class strength and total mortality) with an array of simple and more structured observation error regimes simulated. Model-free and model-based indicators of stock status were employed in the management procedures. On the basis of stochastic stock-specific simulations, we identified the following key determinants of successful management procedures: (i) adequate specification of the stock-recruit relationship (model structure, parameter estimates and variability), (ii) knowledge of the magnitude and structure of the variation in the survey indices, and (iii) explication of the particular management objectives, when assessing management performance. More conservative harvesting strategies are required to meet specified targets in the presence of increasing stochasticity, due to both process and observation error. It was seen that survey-based operational management procedures can perform well in the absence of commercial data, and can also inform aspects of survey design with respect to acceptable levels of error or bias in the surveys.}}, Publisher = {{EDP SCIENCES S A}}, Address = {{17, AVE DU HOGGAR, PA COURTABOEUF, BP 112, F-91944 LES ULIS CEDEX A, FRANCE}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Pomarede, M (Reprint Author), Imperial Coll, Fisheries Grp, Div Biol, Silwood Pk, Ascot SL5 7PY, Berks, England.

One issue is the accurate identification of age cohorts from the survey data. In this paper a length-based approach is described that removes the problem of cohort determination. A bootstrap technique (consistent with the current CCAMLR approach) is used to estimate the length distribution of the population from the survey data which, in conjunction with the bootstrapped survey biomass data, yields an estimate of the population numbers-at-length. A comparison of this method and the existing age-based CMIX/GYM methodology showed very good agreement in calculated yields for 2006, 2007 and 2009, and some differences for 2008 which were explained by an unusual length distribution from which it was difficult to reliably estimate age composition in CMIX. Using the 2009 survey data and the new methodology, a TAC was calculated according to the CCAMLR decision rules of 1 577 and 933 tonnes for the 2009/10 and 2010/11 fishing seasons respectively.

In agriculture, there has been a long history of using levy funds and public and private insurance schemes to mediate economic risks to growers resulting from environmental variability and quarantine risks. In the United States, the federal government continues to underwrite funds (collected by contracted private agents) that are used to protect contributors from the effects of extreme weather and pest and disease losses. In Europe, there are examples of industry-based mutual funds to mediate risks from exotic agricultural diseases. In agriculture, insurance mechanisms have been successful in reducing risk-inducing behaviour by contractual compliance to risk-reducing codes of practice. For fisheries, insurance may provide a tool to address some elements of uncertainty in a way that would help both the fishing industry and the regulators achieve objectives of sustainability, income security, and productivity. This paper presents a brief review of insurance in agriculture and capture fisheries and uses a stochastic model to illustrate how insurance funds could protect revenue and encourage increased sustainability of fisheries and improve compliance with and enforcement of fisheries regulation. Although insurance may be a partial solution to unsatisfactory fisheries management and fishing performance, some potential challenges to this novel approach are also discussed.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Mumford, JD (Reprint Author), Univ London Imperial Coll Sci Technol \& Med, Ctr Environm Policy, Silwood Pk,Buckhurst Rd, Ascot SL5 7PY, Berks, England.

Removals are simulated as total mortality modulated using a selectivity pattern and a fishing activity coefficient. ALADYM uses the classical equations of population dynamics to create a tool that uses fishery-independent information (e. g. from trawl surveys) as the primary source. The formulation of population dynamics at a small time scale (month) allows to model the effects of harvest controls that evolve through the year, which is particularly useful for fast growing species. The possibility of specifying a vector of natural mortality by age/length makes the model more suitable for situations where stocks are exploited at an early life stage, as in many Mediterranean fisheries, while introducing variations along the time of the harvesting pattern accounts for non-equilibrium situations. Stochastic effects can be added to some key life-history traits to incorporate uncertainty in input parameters and in their relationships.

Trawl surveys seldom allow absolute estimates of fish population sizes but, if appropriately located, timed, and designed, can provide a broad range of information about catchable fish species and the ecosystem that supports them. This information may be more conducive to sustainable management of fisheries than the traditional focus on the abundances of selected stocks. The paper first briefly proposes how survey-based methods might supplement existing fishery-dependent stock assessments, as would be necessary during a transition phase to a more ecosystem-orientated system of management. Full survey-based management is then considered in relation to management objectives, the selection of indicators, survey design, reference periods, levels and directions, statistical aspects, CPUE-based assessments, and management responses to good and bad signals from the ecosystem. We argue that existing fishery-dependent stock assessments cannot be claimed to produce absolute estimates of stock abundance and fishing mortality because natural mortality (M) is seldom known accurately and, therefore, that they should not be presumed superior to the relative information from surveys, and an agreeable form of adaptive management.}}, Publisher = {{EDP SCIENCES S A}}, Address = {{17, AVE DU HOGGAR, PA COURTABOEUF, BP 112, F-91944 LES ULIS CEDEX A, FRANCE}}, Type = {{Review}}, Language = {{English}}, Affiliation = {{Woillez, M (Reprint Author), Ctr Geosci Geostat, 35 Rue St Honore, F-77300 Fontainebleau, France.

Six different scenarios were examined including Mediterranean-wide seasonal closures of different duration and an effort reduction scheme. Recruitment was assumed to vary in levels either predicted by a Beverton-Holt stock-recruitment relationship or around an average value estimated from the latest assessment accomplished by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Simulations projected the levels of landings, spawning stock biomass (SSB), gross and net revenue for a period of twenty years. Considering the estimated statistical uncertainty, gains in terms of landings and SSB from short fishery closures (e.g. one month) will be negligible. On the contrary, seasonal closures of at least four months would result in important long-term gains, which are more profound in the case of SSB and net revenue. The ICCAT convention objectives concerning SSB. can only be met with drastic closures (i.e. six months). However, drastic closures would result in short-term decreases in landings and revenues, which should be taken into account before such measures are adopted. (C) 2008 Elsevier B.V.

Despite simultaneously having a large adult population, historically low exploitation, and Marine Stewardship Council accreditation (implying sustainability), there have been an unprecedented 6 sequential years of poor juvenile production (recruitment). Analysis suggests that the poor recruitment arises during the larval overwintering phase, with recent survival rates greatly reduced. Contemporary warming of the North Sea has caused significant changes in the plankton community, and a recently identified regime shift around 2000 shows close temporal agreement with the reduced larval survival. It is, therefore, possible that we are observing the first consequences of this planktonic change for higher trophic levels. There is no indication of a recovery in recruitment in the short term. Fishing mortality is currently outside the agreed management plan, and forecasts show a high risk of the stock moving outside safe biological limits soon, potentially precipitating another collapse of the stock. However, bringing the realized fishing mortality back in line with the management plan would likely alleviate the problem. This illustrates again that recruitment is influenced by more than just spawning-stock biomass, and that changes in other factors can be of equal, or even greater, importance. In such dynamically changing environments, recent management success does not necessarily guarantee future sustainability.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Payne, MR (Reprint Author), Natl Inst Aquat Resources DTU Aqua, Charlottenlund 2920, Denmark.

Understanding the dynamics of recruitment at low stock sizes is crucial to the simulation of stocks as they recover. Compensation in recruitment has occurred in North Sea herring, and it was stronger after the collapse of the stock. The compensation appears to be a product of both increased production of larvae per spawner and increased survival to the juvenile stage. There is only slight evidence for depensation and the point at which North Sea herring has zero recruitment appears close to the origin. There is more variability in recruits per unit spawning stock size when the stock is smaller, this is probably as a result of the potential larger diversity in contributions from spawning components in an unexploited stock compared to an overexploited stock. Mimicking this dynamic in population models will increase the uncertainties in a projection of stock recovery. The lack of observations at higher stock sizes hinders our ability to compare the dynamics of recruit to SSB across the full range of stock sizes, however, recent apparent over-compensation at higher spawning biomass has resulted in less than one recruit per mature adult being produced per year.

First, alternative fishing trip choices of this fleet were identified using multivariate statistical methods based on species landings weighted by value and defined as distinct fishing activity or fisheries (termed metiers). A RUM was specified, which included trip components as attributes during the period 20012004 ( a lagged percentage of the value per unit of effort of the main species caught, total value per unit of effort, and inertia in terms of changes from one metier to another). For the main metiers, the proportion of correct effort allocation is 90\% during the calibration period of 2001-2004. The results from the RUM are used to parameterize a simulation model of trip choice.

As part of the review process, a quantitative management strategy evaluation (MSE) was undertaken, both of the existing plan and of proposed modifications. The evaluation was implemented in the R programming system, using FLR libraries, and was based on stochastic simulations of the complete fishery system (including a biological operating model, a knowledge production model with ``live{''} stock assessments, and a simple implementation model). The generation of appropriate time-series of recruitment was of key importance for a stock like North Sea haddock which produces sporadic large year-classes. Although some refinement of growth and discard models is still required, tentative conclusions can be reached on the likely efficacy of different management plans.

Although they were generally robust to biological uncertainty, fishing at F(pa) for sole could lead to stock collapse under one biological scenario. Adoption of alternative targets would reduce reliance on current reference points as stocks moved to a more sustainable state. Maximum sustainable yield (MSY), maximum economic yield (MEY), and maximum employment conditions implied different effort levels in the two fleets modelled, and different profits.

Changes in stock biology affected the fishing effort required to maximize employment within the fishery, whereas MSY, F(max), and MEY targets were robust to this uncertainty.

Fishing spans all oceans and the impact on ocean predators such as sharks and rays is largely unknown. A lack of data and complicated jurisdictional issues present particular challenges for assessing and conserving high seas biodiversity. It is clear, however, that pelagic sharks and rays of the open ocean are subject to high and often unrestricted levels of mortality from bycatch and targeted fisheries for their meat and valuable fins. 2. These species exhibit a wide range of life-history characteristics, but many have relatively low productivity and consequently relatively high intrinsic vulnerability to over-exploitation. The IUCN-World Conservation Union Red List criteria were used to assess the global status of 21 oceanic pelagic shark and ray species. 3. Three-quarters (16) of these species are classified as Threatened or Near Threatened. Eleven species are globally threatened with higher risk of extinction: the giant devilray is Endangered, ten sharks are Vulnerable and a further five species are Near Threatened. Threat status depends on the interaction between the demographic resilience of the species and intensity of fisheries exploitation. 4. Most threatened species, like the shortfin mako shark, have low population increase rates and suffer high fishing mortality throughout their range. Species with a lower risk of extinction have either fast, resilient life histories (e.g. pelagic stingray) or are species with slow, less resilient life histories but subject to fisheries management (e.g. salmon shark). 5. Recommendations, including implementing and enforcing firming bans and catch limits, are made to guide effective conservation and management of these sharks and rays.

In many cases these declines have been reversed thanks to a variety of effective conservation programs. Several nesting populations maintain positive growth trends, although most are probably depleted relative to historic levels, while others continue in a severely depleted state, with little or no population growth in recent decades. This mosaic of population trajectories along with demographic and life-history traits that buffer against extinction has created unique challenges for marine turtle assessments such as those by the World Conservation Union's (IUCN) Marine Turtle Specialist Group, which conducts global assessments for the IUCN Red List. While the Red Listing approach describes extinction risk, which theoretically can be useful for developing conservation priorities, the descriptors that have been assigned to marine turtles so far (e.g. Vulnerable, Endangered, Critically Endangered) state an unrealistic imminence of extinction, a problem enhanced by the fact that its global resolution fails to reflect the disparate population trends ongoing in different regions worldwide. Coupled with misuse of the Red List by governments and conservation organizations worldwide, these shortcomings have led to increased debate regarding its efficacy for marine turtles. In this paper we describe the Red Listing assessment process, the problems associated with this approach for marine turtles, as well as the overall value of Red List assessments for marine turtle conservation. We suggest that Red list assessments for marine turtles at the global scale do not accurately depict the current status of marine turtles and may have unintended consequences for their conservation. Largely the data do not exist, or are not reliable, making the use of the current criteria intractable.

Although the need to develop alternative novel management strategies that are able to meet their goals is widely recognized, it is almost impossible to achieve this by conducting large-scale experiments on fish populations. There has therefore been a trend towards the use of computer simulation to identify management strategies that can satisfy multiple objectives and that are robust to uncertainty. This chapter introduces harvest control rules (HCRs), and reviews the use of the Management Strategy Evaluation (MSE) framework, including its role in the transformation of HCRs into management procedures. Several examples of the implementation and use of the MSE framework around the world are given, and potential benefits and problems are discussed. Finally, the paper discusses the possible role of the MSE framework in implementing agreements under the World Summit on Sustainable Development and ecosystem-based fisheries management.}}, Publisher = {{BLACKWELL SCIENCE PUBL}}, Address = {{OSNEY MEAD, OXFORD OX2 0EL, ENGLAND}}, Type = {{Article; Book Chapter}}, Language = {{English}}, Affiliation = {{De Oliveira, JAA (Reprint Author), Ctr Environm Fisheries \& Aquaculture Sci, Pakefield Rd, Lowestoft NR33 0HT, Suffolk, England.

We conclude that multispecies models have proved useful, in particular they have shown that natural predators may take of the same order of prey fish as fishing vessels, they have provided information on the long-term prognosis for stock recovery, and they have been used to evaluate precautionary reference points for fishery management. However, the course of history has not always run smoothly, and scientists have found it difficult to describe adequately the functional relationships that exist between predators and their prey. Added to this, there are infinite ways to configure complex foodweb models, so it is often very difficult to discern the main influences on model outputs. Several promising avenues for future research are described, including individual- and size-based models, stochastic multispecies models, and coupled biogeochemical and fisheries models.

Of about 30 species that occur within that area, the roundnose grenadier Coryphaenoides rupestris is one of the main target species of deep-water fisheries. Roughhead grenadier Macrourus berglax is a minor bycatch of other deep-water fisheries and an occasional target of sonic small fisheries. Other macrourid species are not commercially exploited because they are too small and/or in too deep waters, but sonic are also taken as accidental bycatch. There are three main fisheries for roundnose grenadier: north and west of the British Isles, Skagerrak, and Mid-Atlantic Ridge. The Skagerrak fishery is mainly for fish meal while the others are for human consumption. Due to data availability, a range of assessment methods has been trialled primarily for stocks to the north and west of the British Isles. Although uncertain, these assessments provide evidence that the stock has been severely depleted. Fisheries were largely unregulated until the early 2000s, but following repeated International Council for the Exploration of the Sea (ICES) advice, total allowable catches were introduced in 2003 together with effort and capacity regulations. Roundnose grenadier is the most studied species. It lives more than 50 years, compared to 30 years or more for roughhead grenadier. The limited knowledge of other species suggests a contrasting picture of maximum age ranging from 10 to 40 years. Taking into account the limited biological knowledge for these species, the pros and cons of the current management regime are discussed.}}, Publisher = {{AMER FISHERIES SOC}}, Address = {{5410 GROSVENOR LANE, STE 110, BETHESDA, MD 20814-2199 USA}}, Type = {{Proceedings Paper}}, Language = {{English}}, Affiliation = {{Lorance, P (Reprint Author), IFREMER, Dept Ecol \& Modeles Halieut, Rue Iile Yeu,BP 21105, F-44311 Nantes 03, France.

Discarding represents a potentially significant loss to the productivity of fish stocks; it can have damaging ecological consequences, and is a potential cause of the failure of recovery plans. The Nephrops fishery in the North Sea is classified as a mixed fishery. Nephrops trawls are constructed with smaller meshes than trawls used to target whitefish; consequently, the bycatch of juvenile fish can be substantial. Several new Nephrops trawl designs have been tested in the North Sea. The data from these trials are used to investigate the potential impact of their implementation on cod, haddock and whiting stocks in the North Sea (including the Kattegat and Skagerrak). The model examines five trawl designs, and also the scenarios of a cessation of discarding in all North Sea fisheries and in just the Nephrops fishery. The model is deterministic, and evaluates the relative differences between scenarios assuming all other variables remain constant. If discarding of cod, haddock and whiting in the North Sea fisheries were eliminated, stocks would increase by 41\%, 14\% and 29\%, respectively, within 10 years. Eliminating discarding in the Nephrops fishery alone would increase stocks by 2\%, 1\% and 13\%, respectively, reflecting the relative proportion of catches of these species in the Nephrops fishery. For cod and haddock, the introduction of the Nephrops trawl with a grid with a square-mesh codend was the only scenario in which a notable increase in stock number was observed. This trawl design facilitates the escape of fish of all ages/sizes from the trawl, effectively making the Nephrops fishery a single-species fishery. For whiting, stock numbers and landings increased under all scenarios, but forecasted landings were lower than if current discard patterns continued in all except the no-discards scenario. The dependency of the results on the validity of the assumptions and on the accuracy of the input data is discussed. (C) 2007 Elsevier B.V.

Currently, the strength of a year class cannot be confirmed before it is fully recruited to the fishery and has reached the age of 5 years. The only fishery-independent information available is an estimate of egg abundance made every third year. The state of the stock is considered uncertain, and there is no agreed management plan. Following EU requests, a set of harvest control rules (HCRs) that allows for the increased proportion of juvenile fish taken by the fishery in recent years was tested by simulation. The proposed HCRs are based either on the results of a full assessment (Constant-proportion strategy) or simply on the egg estimate used as an indicator of stock status (Slope strategy). Biological risk is compared for scenarios where: (i) uncertainty regarding stock dynamics and in the relationship between egg data and spawning-stock biomass is high (current situation); (ii) variable fractions of the total allowable catch (TAC) are taken in the areas occupied by juveniles and adults; and (iii) there is an implementation error. Results suggest that taking a larger portion of the TAC in the area occupied by juveniles increases the risk of impaired recruitment. Comparison of the Constant-proportion and Slope strategies suggests that the former is more conservative, if the assessment is unbiased or if bias is low. Given the paucity of fishery-independent data, a strategy resulting in an approximately constant catch may be appropriate for this stock.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article; Proceedings Paper}}, Language = {{English}}, Affiliation = {{Roel, BA (Reprint Author), Cefas Lowestoft Lab, Pakefield Rd, Lowestoft NR33 0HT, Suffolk, England.

Such modelling is characterized by specification of an operating model (OM) representing the underlying truth and a management procedure that mimics the process of acquiring knowledge, formulating management decisions, and implementing those decisions. We employ such a model to evaluate a management plan for North Sea flatfish proposed by the North Sea Regional Advisory Council in May 2005. Focus is on the construction and conditioning of OMs, key requirements for such simulations. We describe the process of setting up and validating OMs along with its effects on the ability to communicate the results to the stakeholders. We conclude that there is tension between the level of detail required by stakeholders and the level of detail that can be provided. In communicating the results of simulations, it is necessary to make very clear how OMs depend on past perceptions of stock dynamics.}}, Publisher = {{OXFORD UNIV PRESS}}, Address = {{GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND}}, Type = {{Article; Proceedings Paper}}, Language = {{English}}, Affiliation = {{Pastoors, MA (Reprint Author), Wageningen IMARES, POB 68, NL-1970 AB Ijmuiden, Netherlands.
