    "notes": "The Alaska salmon canning industry began in 1878 with the first cannery at Old Sitka (Southeast AK) and at Klawock. The Karluk River (Kodiak) became the dominant pack site by 1890. At peak, 160+ canneries operated across Alaska. The first salmon hatchery was built at Afognak in 1891 (BCF). All pre-1960 data from Van Hyning (1951) and BCF historical reports."
