Book Description
The Alaska Department of Fish and Game (ADF&G), actively manages chum salmon fisheries in the Yukon River drainage. The purpose of the Anvik River sonar project is to monitor escapement of summer chum salmon Oncorhynchus keta and pink salmon O. gorbuscha in the Anvik River drainage, believed to be the largest producer of summer chum salmon in the Yukon River drainage (Hayes et al. 2008, Larson et al. 2017). Timely and accurate reporting of information from the Anvik River sonar project helps Yukon River fishery managers ensure the Anvik River Biological Escapement Goal (BEG) of 350,000 to 700,000 summer chum salmon is met (ADF&G 2004). This assessment is necessary to determine if summer chum salmon abundance will meet downstream harvest and upstream escapement needs. Fishery openings and closures may be based in part upon this assessment. This project uses imaging sonar equipment on the Anvik River to generate timely, in-season passage estimates of salmon (Brodersen 2021). Beach seine sampling is conducted to collect biological data used in characterizing the summer chum salmon run and tower estimates are used to apportion passage estimates to species. The project site is located approximately 76 km upstream from the mouth of the Anvik River (Figures 1 and 2) and is scheduled to operate continuously from approximately June 16 through July 26, 2023.

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
An interdivisional team of staff from the Alaska Department of Fish and Game met beginning in March 2019 to review existing Pacific salmon (Oncorhynchus) escapement goals in the Kodiak Management Area (KMA) and make recommendations to the directors of the divisions of Commercial Fisheries and Sport Fish. The KMA salmon escapement goals had been reviewed previously in 2016. The current review team recommends 21 goals remain unchanged, and 1 goal be revised (Olds River coho salmon [O. kisutch] lower bound sustainable escapement goal of 500). In addition, a change in designation from a biological escapement goal to a sustainable escapement goal is recommended for 3 goals (Afognak River sockeye salmon [O. nerka], Upper Station late-run sockeye salmon, and Buskin River coho salmon). When combined with existing escapement goals, these staff recommendations to the directors of the divisions of Commercial and Sport Fisheries result in 22 escapement goals for the KMA in 2019: 12 for sockeye salmon, 2 for Chinook salmon (O. tshawytscha), 4 for coho salmon, 3 for pink salmon (O. gorbuscha), and 1 for chum salmon (O. keta).
