Book Description
The Alaska Department of Fish and Game interdivisional escapement goal review committee reviewed Pacific salmon Oncorhynchus spp. escapement goals for Southeast Alaska in August of 2019 and again early in 2020. Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. There is a total of 47 escapement goals in Southeast Alaska for 11 Chinook, 12 sockeye, 13 coho, 3 pink, and 8 chum salmon stocks. The Southeast escapement goal review committee recommended changes to these goals to the directors of the Divisions of Commercial Fisheries and Sport Fish as follows: (1) change the Taku River sockeye salmon sustainable escapement goal range of 71,000–80,000 fish (based on a historical dataset) to a biological escapement goal range of 40,000–75,000 fish based on a revised dataset; and (2) change the Situk River coho salmon biological escapement goal range of 3,300–9,800 fish to a sustainable escapement goal range of 3,800–9,600 fish based on percentiles of historical survey counts. Detailed analyses of Chilkoot, Speel, and Redoubt Lakes sockeye salmon escapement goals are also documented here, although the committee did not recommend changes to those goals.

Book Description
The Alaska Department of Fish and Game interdivisional escapement goal review committee reviewed Pacific salmon Oncorhynchus spp. escapement goals for Southeast Alaska in 2017. As of 2016, 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 changes to escapement goals to the directors of the divisions of Commercial Fisheries and Sport Fish as follows: (1, 2, 3) replace escapement goal ranges for Chickamin, Blossom, and Keta river Chinook salmon, which are expressed in index survey counts, with ranges expressed as total escapement; (4) eliminate the Klukshu (Alsek) River Chinook salmon goal; (5) eliminate the combined East Alsek-Doame river sockeye salmon biological escapement goal (13,000-26,000 fish) and replace it with a sustainable escapement goal (range 9,000-24,000 fish) germane only to the East Alsek River; (6) eliminate the Lost River sockeye salmon goal; (7) eliminate the Alsek River sockeye salmon goal (8); change the Berners River coho salmon biological escapement goal from 4,000-9,200 fish to 3,600-8,100 fish; (9) change the Tsiu-Tsivat river coho salmon goal from a biological escapement goal to a sustainable escapement goal while maintaining the same goal of 10,000-29,000 fish; (10) eliminate the Ford Arm Creek coho salmon goal; (11) eliminate the Situk River pink salmon goal; and (12) change the aggregate Northern Southeast Inside summer-run chum salmon lower bound sustainable escapement goal from 119,000 to 107,000 fish. As a result of these recommendations, a total of 47 Southeast Alaska escapement goals would be established for 11 Chinook, 12 sockeye, 13 coho, 3 pink, and 8 chum salmon stocks.

Book Description
The Alaska Department of Fish and Game (ADF&G) interdivisional escapement goal review committee (committee) reviewed 41 escapement goals for Pacific salmon Oncorhynchus spp. stocks in Lower Cook Inlet (LCI). Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Salmon Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. All of the existing goals were adopted in 2017, except for 1 chum salmon O. keta stock (McNeil River, adopted 2007) and 2 sockeye salmon O. nerka stocks (Bear and English Bay Lakes, adopted 2001). Except for 2 Chinook salmon O. tshawytscha stocks (Anchor and Ninilchik Rivers) and 4 sockeye salmon stocks (English Bay, Bear, Mikfik, and Chenik Lakes), salmon escapements in LCI are primarily monitored by single or multiple aerial and/or foot surveys of appropriate stream reaches. The resulting escapement indices do not provide absolute abundance estimates suitable for estimating biological escapement goals (BEG). Consequently, all LCI goals are sustainable escapement goals (SEG). There are no escapement goals for coho salmon O. kisutch in LCI. To improve management flexibility and consistency between management areas in Alaska, the committee supported LCI transitioning from stock-specific SEGs for pink (O. gorbuscha, 18 stocks) and chum (12 stocks) salmon to aggregate escapement goals for each of the 3 LCI districts with commercial fisheries targeting these species (Southern, Outer, and Kamishak). ADF&G will continue managing LCI Chinook (3 stocks) and sockeye (8 stocks) salmon using stock-specific SEGs, with 2 Chinook (Anchor and Ninilchik Rivers) and 2 sockeye salmon (Bear and English Bay Lakes) goals changing during this review period.

Book Description
In October 2020, an interdivisional team of staff from the Alaska Department of Fish and Game reviewed existing Pacific salmon Oncorhynchus escapement goals in the Chignik Management Area (CMA). The 6 CMA salmon escapement goals were last reviewed in 2018. Starting in 2020, the team reviewed recent data to determine whether substantial new information existed to warrant analyzing and updating the goals. The team determined Chignik sockeye salmon warranted further review. The team revised the early- and late-run sockeye salmon goals to a single biological escapement goal (BEG) of 450,000 to 800,000 fish to address overlaps and subsequent bottlenecks in freshwater rearing between the 2 major stocks. The early- and late-run sockeye salmon goals will be eliminated, and no new goals were added for systems currently without escapement goals.
