The primary goal of this study is to use mixed stock analysis to estimate the stock composition of chum salmon Oncorhynchus keta harvested in South Alaska Peninsula Management Area (southern portion of Area M) commercial salmon fisheries during the 2022 to 2026 seasons. Relatively large harvests of chum salmon in South Alaska Peninsula fisheries in recent years corresponding with small returns of chum salmon to Western Alaska rivers has raised concerns among some stakeholders about the stock-specific harvests in South Alaska Peninsula fisheries. Salmon tagging studies published in 1926, 1964, and 1991 and subsequent genetic stock identification projects conducted in 1993-1996 and 2007-2009 demonstrated significant numbers of non-local chum salmon in the June and early July commercial fisheries of the South Alaska Peninsula. Presently, some stakeholders believe that relative abundances among stocks in the fishery have changed since stock-specific chum harvests were last estimated in South Alaska Peninsula harvests as part of the Western Alaska Salmon Stock Identification Program (WASSIP) in 2007-2009. An updated study that accurately and precisely estimates stock-specific harvests would help resolve these concerns and provide valuable management information regarding the gear- and temporal-specific harvests of chum salmon in select South Peninsula fisheries. This operational plan provides the Alaska Department of Fish and Game (ADF&G) with a sampling and genetic analysis plan to achieve that overall goal.

This report summarizes the 2022 season and historical commercial salmon fisheries of the South Alaska Peninsula Management Area (southern portion of Area M). The 2022 commercial salmon harvest (including the ADF&G test fishery) in the South Alaska Peninsula of Area M was 14,505 Chinook salmon Oncorhynchus tshawytscha, 4,387,007 sockeye salmon O. nerka, 46,619 coho salmon O. kisutch, 5,864,792 pink salmon O. gorbuscha, and 822,314 chum salmon O. keta. Harvest of sockeye salmon was above the recent 10-year average (2012–2021). Harvest of Chinook, coho, pink, and chum salmon were all below the most recent 10-year averages. A total of 245 permit holders participated in the fishery. The June commercial salmon harvest included 3,204 Chinook, 3,905,017 sockeye, 169 coho, 1,201,771 pink, and 544,097 chum salmon. The post-June commercial salmon harvest, excluding the Southeastern District Mainland (SEDM) harvest from June 1–July 25, was 10,308 Chinook, 450,832 sockeye, 46,424 coho, 4,648,137 pink, and 269,680 chum salmon. Limited commercial fishing in the SEDM occurred between July 1–July 25 in the Orzinski Bay Section. Harvest in the Orzinski Bay Section included 7 Chinook, 15,177 sockeye, 2 coho, 7,236 pink, and 431 chum salmon. The South Alaska Peninsula post-June salmon harvest in the SEDM from July 1 through October 31 was 231 Chinook, 41,140 sockeye, 4,884 coho, 376,602 pink, and 35,970 chum salmon. In 2022, the Orzinski Lake sockeye salmon escapement of 17,283 sockeye salmon was within the sustainable escapement goal (SEG) of 15,000–20,000 sockeye salmon. Total escapement of pink salmon (5,177,350 fish) was above the South Alaska Peninsula SEG range of 1,750,000–4,000,000 fish. In the Southeastern District, chum salmon escapement was estimated at 155,702 fish, within the SEG of 106,400–212,800 fish. In the South Central District, chum salmon escapement was estimated at 167,700 fish, within the SEG range of 89,800–179,600 fish. In the Southwestern District, chum salmon escapement was estimated at 74,200 fish, below the SEG range of 133,400–266,800 fish.

Uncertainty about the magnitude, frequency, location, and timing of the nonlocal harvest of sockeye and chum salmon was the impetus for the Western Alaska Salmon Stock Identification Program. The program was designed to use genetic data in mixed stock analysis to reduce this uncertainty. A baseline of allele frequencies in spawning populations is required for use in mixed-stock analysis to estimate the stock of origin of harvested fish. This report describes the methodology used to understand the population genetic structure among chum salmon populations and to build and test a baseline for use in mixed stock analysis of chum salmon. Of the 35,921 fish from 434 collections selected to be genotyped, the final baseline was composed of 32,817 fish from 402 collections representing 310 populations. Average population sample size was 106 fish. Reporting groups were determined through a combination of stakeholder needs and identifiability using genetic information, as measured using proof tests. The final reporting groups included Asia, Kotzebue Sound, Coastal Western Alaska, Upper Yukon River, Northern District (Alaska Peninsula), Northwest District (Alaska Peninsula), South Peninsula (Alaska Peninsula), Chignik/Kodiak, and East of Kodiak.

During June chum salmon are caught incidentally by commercial seine and gillnet fishers targeting sockeye salmon in the southern Alaska Peninsula (the False Pass fishery). A portion of this chum catch is believed to be bound for Arctic-Yukon-Kuskokwim river systems. This report examines the impact of harvesting these chum salmon on the economies and salmon fisheries of western Alaska in response to concern of uncontrolled growth of the commercial chum harvest and decrease chum salmon runs in some western Alaska rivers.

This report is a summary of the 2022 season and historical data concerning management of the commercial salmon fisheries of the Northwestern and Northern Districts of the North Alaska Peninsula in the Alaska Peninsula Management Area (Area M). Most commercial salmon fishing effort on the North Alaska Peninsula targeted sockeye salmon Oncorhynchus nerka. The 2022 commercial salmon harvest on the North Alaska Peninsula was 887 Chinook O. tshawytscha, 3,604,235 sockeye, 7,711 coho O. kisutch, 12,362 pink O. gorbuscha, and 14,095 chum O. keta salmon. The North Peninsula Chinook salmon harvest was below the 10-year average (2012–2021) of 1,879 fish. The sockeye salmon harvest in the Northern District of 3,548,252 fish exceeded the 10-year average harvest of 2,208,966 fish. The North Alaska Peninsula chum salmon harvest of 14,095 fish was below the 10-year average of 137,651 chum salmon, with nearly all (9,316 fish) of the harvest occurring in the Izembek-Moffet Bay Section of the Northwestern District. The total exvessel value of all North Peninsula fisheries is estimated to be $29.3 million. The exvessel value was well above the recent 10-year average of $17.0 million. The majority of the North Peninsula fisheries’ value is composed of sockeye salmon harvested in the Northern District ($28.8 million).

The South Alaska Peninsula Management Area (Area M) commercial salmon fisheries are regulated by 3 management plans. The South Unimak and Shumagin Islands June fisheries occur from June 6 through June 28 and target sockeye salmon Oncorhynchus nerka. The June fisheries commence according to one schedule that combines all gear types. The post-June fishery may occur from July 6 through October 31 and is guided by the results of an immature salmon test fishery and the strength of local sockeye, chum O. keta, pink O. gorbuscha, and coho salmon O. kisutch returns. The Southeastern District Mainland (SEDM) is managed independently from the remainder of the South Alaska Peninsula fisheries from June 1 through October 31. A sockeye salmon allocation exists between the Chignik Management Area (CMA) and the SEDM where up to 7.6% of the sockeye salmon harvested in the CMA may be harvested in the SEDM. Of the sockeye salmon harvested in the SEDM during the allocation timeframe (June 1 through July 25, excluding the Northwest Stepovak Section from July 1 through July 25), 80% are attributed to the allocation. After July 25, the SEDM is managed strictly on local stocks. This document summarizes the management strategy of the South Alaska Peninsula fisheries and outlines the requirements for industry participation in 2022.

This report provides the Alaska Board of Fisheries with information on Yukon Area salmon stock status, including escapement and harvest data for the January 2023 regulatory meeting. In response to the guidelines established in the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222), the Alaska Board of Fisheries (board) classified the Yukon River Chinook salmon Oncorhynchus tshawytscha stock as a stock of yield concern at its September 2000 work session. An action plan was developed by the Alaska Department of Fish and Game and acted upon by the board in January 2001. The status as a yield concern was continued for Yukon River Chinook salmon at the January 2004, 2007, 2010, 2013, 2016, and 2019 board meetings. Chinook salmon escapement goal performance has been mixed throughout the past 5 years (2018–2022) throughout the Alaska portion of the Yukon River drainage, but escapement goals were not met from 2020 to 2022. Conservative management actions taken inseason have included full subsistence fishery closures to protect low runs as they migrate upriver. Additionally, Yukon River summer chum, fall chum O. keta, and coho salmon O. kisutch recently experienced a drastic decline since 2020. Most escapement goals for chum and coho salmon have not been achieved since 2020 despite significant subsistence, personal use, and commercial fishing restrictions and closures. Historically, the Yukon River chum and coho salmon stocks have met or exceeded escapement goals and provided for subsistence, personal use, and commercial fisheries, with a few exceptions of decreased production in a couple tributaries.
