Review of Salmon Escapement Goals in the Kodiak Management Area, 2019

ISBN:
Category : Escapement (Fisheries)
Languages : en
Pages : 144
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).

Book Description
An interdivisional team of staff from the Alaska Department of Fish and Game met 3 times beginning in March 2016 to review existing Pacific salmon Oncorhynchus spp. escapement goals in the Kodiak Management Area (KMA), for the purpose of making recommendations to the directors of the divisions of Commercial Fisheries and Sport Fish. The KMA salmon escapement goals had previously been reviewed in 2013. The review team recommends 18 goals remain unchanged, the elimination of 2 goals (Uganik Lake sockeye salmon O. nerka lower-bound sustainable escapement goal, and Mainland District chum salmon O. keta aggregate lower-bound sustainable escapement goal), and the revision of 4 goals (Ayakulik Chinook salmon O. tshawytscha biological escapement goal range 4,800?8,400, Karluk River early-run sockeye salmon biological escapement goal range 150,000?250,000, Karluk River late-run sockeye salmon biological escapement goal range 200,000?400,000, and Kodiak Archipelago chum salmon aggregate lower-bound sustainable escapement goal 101,000). 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 2017: 12 for sockeye salmon, 2 for Chinook salmon, 4 for coho salmon O. kisutch, 3 for pink salmon O. gorbuscha, and 1 for chum salmon.
Review of Salmon Escapement Goals in the Chignik Management Area, 2020

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.
Spawner-recruit Analysis and Escapement Goal Recommendation for Kenai River Late-run Sockeye Salmon

Book Description
The current sustainable escapement goal (700,000–1,200,000) for Kenai River late-run sockeye salmon was established in 2011. For this escapement goal review, the escapement time series and production data were updated through 2018. The fit of 6 spawner–recruit models to data from brood years 1968–2012 and brood years 1979–2012 was examined. Although the classic Ricker model was determined the most appropriate to use given the data, all brood years were estimated to have replaced themselves, which compromised obtaining accurate and precise estimates of most model parameter estimates and biological reference points, including a scientifically defensible estimate of maximum sustained yield. Markov-type yield tables were constructed to evaluate yields at different levels of escapement. We recommend the sustainable escapement goal for Kenai River late-run sockeye salmon be revised to 750,000–1,300,000 fish because the analyses indicated escapements in this range will likely provide better yields.
Review of Salmon Escapement Goals in the Alaska Peninsula and Aleutian Islands Management Areas, 2018

Book Description
In January 2018, an interdivisional team, including staff from the Division of Commercial Fisheries and the Division of Sport Fish, was formed to review Pacific salmon Oncorhynchus sp. escapement goals in the Alaska Peninsula and Aleutian Islands Management areas (Area M). This review was 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). Of the 23 existing Area M salmon escapement goals evaluated, the team recommended revising 6 goals, discontinuing 1 goal, and leaving the remaining 16 goals unchanged. After a comprehensive review of the available data, the team recommended that no changes in the current sustainable escapement goals (SEGs) were warranted for 10 sockeye salmon O. nerka systems that include runs to Orzinski, Bear (early and late run), and Thin Point lakes; Mortensens, and Christianson lagoons; and the Cinder, Meshik, Sandy, and Ilnik rivers. No change was recommended for the sockeye salmon biological escapement goal (BEG) at Nelson River. In addition, the team recommended no changes to two of the current aggregate district SEGs for chum salmon O. keta in the North Peninsula, and two coho salmon O. kisutch goals at Nelson and Ilnik rivers. The team did recommend revision of six goals (Nelson River Chinook salmon O. tshawytscha BEG 2,400 to 5,000; McLees Lake sockeye salmon Lower Bound-SEG greater than 10,000; North Creek sockeye salmon SEG 7,500 to 10,000; Southeastern District aggregate chum salmon SEG 62,500 to 151,800; South Central District aggregate chum salmon SEG 68,900 to 99,200; Southwestern District aggregate chum salmon SEG 86,900 to 159,900). The chum salmon aggregate goal reviews incorporated a reduction to the number of index streams, which accounts for the apparent large changes in these goals. The Swanson Lagoon sockeye salmon escapement goal is recommended to be discontinued.

Of the 22 existing Area M salmon escapement goals evaluated, the team recommended revising 10 goals and leaving the remaining 12 goals unchanged. After a comprehensive review of the available data, the team found that no changes in the current sustainable escapement goals (SEGs) were warranted for sockeye salmon O. nerka system runs to Bear (early and late run) and McLees Lakes, the Cinder, Meshik, and North Creek Rivers, nor for the sockeye salmon biological escapement goal (BEG) for Nelson River. In addition, the team determined no changes were warranted for Nelson River Chinook salmon (O. tshawytscha), South Peninsula pink salmon (O. gorbuscha), or the current aggregate district SEGs for chum salmon O. keta in the Southeastern, South Central, and Southwestern Districts. The team determined revisions were warranted and revised goals for 6 sockeye salmon systems (Ilnik River SEG 40,000–75,000, Sandy River SEG 37,000–69,000, Christianson Lagoon SEG 23,000–50,000, Orzinski Lake SEG 14,000–28,000, Mortensen Lagoon SEG 1,400–5,700, and Thin Point Lake SEG 9,000–19,000), 2 chum salmon systems (Northern District SEG 49,000–132,000 and Northwestern District SEG 49,000–133,000), and 2 coho salmon systems (Nelson River SEG 19,000–29,000 and Ilnik River SEG 9,000–24,000). The chum salmon aggregate goal reviews incorporated a reduction to the number of index streams, which accounts for the apparent large changes in these goals.

Book Description
An Alaska Department of Fish and Game Escapement Goal Review Team (review team) was convened to review salmon escapement goals for the Arctic-Yukon-Kuskokwim Region in preparation for the January 2007 meeting of the Alaska Board of Fisheries. The review team made recommendations to the Regional Supervisors of the Divisions of Commercial Fisheries and Sport Fish, who in turn make recommendations to the directors of the two divisions. The review team recommended establishing three new escapement goals in the Kuskokwim Management Area, no new goals in the Yukon Management Area, and two new goals in the Norton Sound-Port Clarence and Kotzebue Management Areas. In addition they recommended revising three escapement goals in the Kuskokwim Management Area (one for Chinook salmon, one for chum salmon, and one for sockeye salmon), none in the Yukon Management Area, and five chum salmon goals in the Kotzebue Management Area. They also recommended discontinuing one aerial survey escapement goal in the Kuskokwim Management Area where that goal was recommended to be replaced with a weir goal. While most of the recommended new goals are sustainable escapement goals, spawner-recruit analyses were performed to recommend biological escapement goals for Kobuk and Noatak rivers chum salmon in the Kotzebue Management Area and Middle Fork Goodnews River Chinook and Sockeye salmon in the Kuskokwim Management Area. The escapement goal review team also made recommendations for specific stocks to be reviewed in detail prior to the 2010 Alaska Board of Fisheries meeting.
