Book Description
Sport-angler effort and harvest of Chinook salmon Oncorhynchus tshawytscha were estimated from a creel survey conducted at 2 distinct hatchery release sites along the Juneau shoreside from 1 June to 28 August 2022. This time period aligned with liberalized sport bag and possession limits targeting Alaska hatchery Chinook salmon production at a designated sport harvest hatchery area encompassing these 2 hatchery release sites as well as adjacent marine waters. Sport anglers harvested an estimated total of 2,628 Chinook salmon across both hatchery release areas, including 1,462 (SE = 207) at Macaulay Salmon Hatchery and 1,165 (SE = 259) at Fish Creek. The total Chinook salmon harvest observed at Macaulay Salmon Hatchery (1,462) included 1,383 (SE = 207) large and 80 (SE = 80) non-large fish. The total Chinook salmon harvest observed at Fish Creek (1,165) included 982 (SE = 221) large and 183 (SE = 55) non-large fish. Total effort (angler-hours) was estimated at 18,905, including 12,623 (SE = 629) at Macaulay and 6,282 (SE = 481) at Fish Creek. The stock composition based on genetic analysis revealed Chinook salmon harvested in these 2 distinct hatchery release areas were approximately 99% enhanced-origin fish from the Andrew Creek stock. Large Chinook salmon (defined as fish >28สบ total length) dominated the total catch across both areas (approximately 84%). The age composition of large Chinook salmon harvested by sport anglers across both areas was dominated by age-1.3 fish (>80%). Residents comprised about 65% of all interviewed anglers.
