Book Description
The Alaska Department of Fish and Game (ADF&G) interdivisional escapement goal review committee (committee) reviewed Pacific salmon Oncorhynchus spp. escapement goals for major river systems in Lower Cook Inlet (LCI). There were 41 escapement goals evaluated in LCI during this review. Except for 2 Chinook salmon Oncorhynchus tshawytscha stocks (Anchor and Ninilchik rivers) and 4 sockeye salmon O. nerka, 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, ADF&G developed sustainable escapement goals (SEG) for 3 Chinook, 12 chum O. keta, 18 pink O. gorbuscha, and 8 sockeye salmon stocks monitored in LCI. There are no escapement goals for coho salmon O. kisutch in LCI. Escapement performance for Chinook, chum, pink, and sockeye salmon relative to the existing goals has been good during the past 4 years, with a harvestable surplus available in 33--100% of streams during most years. Because most of the current goals were implemented 15 years ago and new methods were recently developed for establishing SEGs, the committee recommended changing 37 of 41 escapement goals for salmon stocks in LCI to incorporate the additional escapement data and new methods.

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
This report summarizes statewide Pacific salmon escapement goals in effect in 2017 and documents escapements for all species and stocks with goals from 2009 through 2017. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. Escapement goals were reviewed for Upper Cook Inlet, Lower Cook Inlet, and Kodiak management areas leading up to the 2016/2017 Board of Fisheries meeting cycle. As a result of these reviews, there were 53 escapement goal changes in 2017, including the elimination of 2 goals, establishment of 2 new goals, and the replacement of the Kenai River early- and late-run Chinook salmon goals based on all fish with escapement goals based on large fish only. In addition, two Optimal Escapement Goals were removed from management plans by the Alaska Board of Fisheries. In 2017, 83% of the escapement goals were met or exceeded and 17% of the stocks did not meet minimum escapement goals.

Book Description
The Alaska Department of Fish and Game interdivisional escapement goal review committee reviewed Pacific salmon Oncorhynchus spp. escapement goals for the major river systems in Upper Cook Inlet. Escapement goals were reviewed for 21 Chinook salmon O. tshawytscha, 1 chum salmon O. keta, 4 coho salmon O. kisutch, and 9 sockeye O. nerka salmon stocks. The committee recommended to the Divisions of Commercial Fisheries and Sport Fish directors changes to 2 Chinook salmon goals (early- and late- run Kenai River), 1 chum salmon goal (Clearwater Creek), and 4 sockeye salmon goals (Chelatna, Judd, and Larson lakes and Fish Creek). The committee also recommended creating 1 Chinook salmon (Little Susitna River; weir-based goal) and 1 coho salmon (Deshka River) escapement goal.

Book Description
This report summarizes statewide Pacific salmon escapement goals in effect in 2020 and documents escapements for all species and stocks with goals from 2012 through 2020. In addition, this report documents changes in escapement goals for both 2019 and 2020 because the report was not published in 2020 due to extenuating circumstances associated with the COVID-19 pandemic. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. Leading up to the 2018/2019 Board of Fisheries meeting cycle, escapement goals were reviewed for the Bristol Bay, Arctic-Yukon-Kuskokwim, Alaska Peninsula/Aleutian Islands, and Chignik Management Areas. As a result of these reviews, there were 29 escapement goal changes in 2019, including the elimination of 10 goals. The remaining changes were due to updates to escapement indices and/or goal development methods. There were no changes to any escapement goals in the Chignik Management Area. For the 2019/2020 Board of Fisheries meeting cycle, escapement goals were reviewed for Upper Cook Inlet, Lower Cook Inlet, and Kodiak Management Areas. As a result of these reviews, there were 32 escapement goal changes in Upper Cook Inlet that included establishing 4 new escapement goals and eliminating 12 goals. There were no escapement goal changes for Lower Cook Inlet. Because of these revisions, there were 272 salmon escapement goals in Alaska in 2019 and 264 escapement goals in 2020. In 2019, 78% of the escapement goals in Alaska were met or exceeded and 22% of the stocks did not meet minimum escapement goals. In 2020, 65% of the escapement goals were met or exceeded and 35% of the stocks did not meet minimum escapement goals.

Book Description
The Alaska Department of Fish and Game interdivisional escapement goal review committee reviewed Pacific salmon (Oncorhynchus spp.) escapement goals for the major river systems in Upper Cook Inlet. Escapement goals were reviewed for 21 Chinook salmon, 1 chum salmon, 4 coho salmon, and 9 sockeye salmon stocks. The committee recommended to the Commercial Fisheries and Sport Fish division directors updates to 7 Chinook salmon goals (Deshka River, Alexander Creek, Chulitna River, Chuitna River, Theodore River, Little Susitna River, and Crooked Creek), consolidation of 10 Chinook salmon goals into 3 goals (Eastside Susitna, Talkeetna River, and Yentna River), a discontinuation of 11 Chinook salmon goals (Goose Creek, Little Willow Creek, Montana Creek, Sheep Creek, Willow Creek, Clear [Chunilna] Creek, Prairie Creek, Talachulitna River, Lake Creek, Peters Creek, and Lewis River), updates to 3 coho salmon goals (Fish Creek, Jim Creek, and Little Susitna River), and updates to 3 sockeye salmon goals (Kasilof River, Kenai River, and late-run Russian River).
