Escapement goal analyses for stocks of Chinook salmon in the transboundary Alsek River and in one of its tributaries, the Klukshu River, are described. Data and estimates for harvest, inriver run size, harvest rates, relative age composition, and escapements for calendar years 1976 through 2007 are provided.

Report discusses escapement goal analyses for stocks of sockeye salmon in the transboundary Alsek River and in one of its tributaries, the Klukshu River. Data and estimates for harvest, in-river run size, harvest rates, relative age composition, and escapements for calendar years 1976 through 2008 are provided.

The Alaska Department of Fish and Game interdivisional escapement goal review committee reviewed Pacific salmon Oncorhynchus spp. escapement goals for Southeast Alaska in 2014. As specified in the Pacific Salmon Treaty, escapement goal recommendations for transboundary Alsek and Klukshu river Chinook and sockeye salmon runs underwent bilateral U.S./Canada review, and recommended changes were adopted by the Transboundary River Panel of the Pacific Salmon Commission in 2013. Thus, as of 2013, escapement goals were established for 12 Chinook, 14 sockeye, 14 coho, 4 pink, and 8 chum salmon stocks. The Southeast escapement goal review committee recommended to the directors of the divisions of Commercial Fisheries and Sport Fish that all but 5 of those escapement goals remain unchanged. The committee recommended (1) changing the Speel Lake sockeye salmon goal from a biological escapement goal range of 4,00-13,000 fish to a sustainable escapement goal range of 4,000-9,000 fish; (2) changing the Lost River coho salmon goal from a lower-bound sustainable escapement goal of 2,200 fish to a sustainable escapement goal range of 1,400-4,200 fish, and changing the name of the goal to Tawah Creek (Lost River); (3-4) increasing aggregate lower-bound sustainable escapement goals for summer-run chum salmon in the Southern Southeast and Northern Southeast Outside subregions to account for the addition of new index streams to those stock groups; and, finally, (5) changing the Chilkat River fall-run chum salmon sustainable escapement goal range of 75,000-170,000 fish to a range of 75,000-250,000 fish.

Estimates of Chinook salmon Oncorhynchus tshawytscha spawning escapement will be summarized for 2021 in 11 Southeast Alaska river systems. Chinook index salmon systems include: Situk River, Alsek River, Chilkat River, Taku River, King Salmon River, Stikine River, Unuk River, Chickamin River, Blossom River, Keta River, and Andrew Creek. Spawning escapements will be estimated using aerial and foot surveys, mark-recapture studies, and weirs. The Alaska Department of Fish and Game and Fisheries and Oceans Canada use these data, along with age composition data to make terminal and regional management decisions, and the Pacific Salmon Commission uses these data for coastwide management and stock assessment.

Estimates of Chinook salmon Oncorhynchus tshawytscha spawning escapement will be summarized for 2020 in 11 Southeast Alaska river systems. Chinook index salmon systems include: Situk River, Alsek River, Chilkat River, Taku River, King Salmon River, Stikine River, Unuk River, Chickamin River, Blossom River, Keta River, and Andrew Creek. Spawning escapements will be estimated using aerial and foot surveys, mark-recapture studies, and weirs. The Alaska Department of Fish and Game and Fisheries and Oceans Canada use these data, along with age composition data to make terminal and regional management decisions, and the Pacific Salmon Commission uses these data for coastwide management and stock assessment.

Estimates of Chinook salmon Oncorhynchus tshawytscha spawning escapement will be summarized for 2019 in 11 Southeast Alaska river systems. Chinook salmon systems include: Situk River, Alsek River, Chilkat River, Taku River, King Salmon River, Stikine River, Unuk River, Chickamin River, Blossom River, Keta River, and Andrew Creek.
