Fleischman and published by . This book was released on 2009 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical escapement and run size of fall chum salmon Oncorhynchus keta was reconstructed from incomplete sonar, weir, counting tower, mark-recapture, aerial survey, and foot survey data of varying precision from 1974 to 2007. The resulting estimates of drainage-wide escapement were fitted to an age-structured Ricker spawner-recruit model. Bayesian statistical methods were employed, which allowed for realistic assessment of uncertainty in the presence of measurement error, serial correlation, and missing data.

This book was released on 2006 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game (ADF & G) convened an Escapement Goal Review Team to review salmon escapement goals for the Arctic-Yukon-Kuskokwim Region in preparation for the January 2007 meeting of the Alaska Board of Fisheries. To support that effort, salmon escapement data and abundance information for the Kuskokwim Area were updated through 2005 and are represented here. From our review of Kuskokwim data we recommend biological escapement goals (BEG) for chinook and sockeye salmon, Oncorhynchus tshawytscha and O. nerka, in the Middle Fork Goodnews River; sustainable escapement goals (SEG) for chinook salmon in the George, Kwethluk, and Tuluksak Rivers; a revised SEG for Aniak River chum salmon O. keta; and that SEGs based on aerial surveys be discontinued for chinook salmon in the Kwethluk and coho salmon, O. kisutch, in the Kanektok River. This report also summarizes much of the historical salmon escapement information for the Kuskokwim Area, but in a manner that is intended to focus on the needs for assessing inter-annual trends for escapement goals. This intent is achieved through an extensive series of appendices that present historical escapement information in a standardized manner. The main body of appendices is preceded by narrative that provides context useful in interpreting the information in the appendices. In many cases data sets in the appendices are truncated in order to address standardization needs. As such, investigators seeking more complete information should consult master escapement files maintained by ADF & G, original aerial survey forms, and detailed project reports.

This book was released on 2018 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Alaska Department of Fish and Game (ADF&G) escapement goal review team evaluated salmon stocks in the Arctic-Yukon-Kuskokwim (AYK) region in advance of the January 2019 Alaska Board of Fisheries (BOF) meeting. At the time of this review there existed 65 escapement goals for salmon stocks in the AYK region, including 5 optimum escapement goals established by the BOF. The review team did not recommend any new escapement goals be established at this time. The review team has recommended that 12 escapement goals be revised and 7 escapement goals be discontinued. The recommendations made by the review team were intended to align salmon escapement goals throughout the region with current fishery management practices and status of escapement monitoring programs. Within the Norton Sound-Port Clarence Area, the review team recommended discontinuing the Norton Sound Subdistrict 1 aggregate chum salmon Oncorhynchus keta goal and revising goals for the Eldorado, Nome, and Snake rivers which contribute to the aggregate. Revisions were also recommended for chum salmon goals established for the Kwiniuk and Tubutulik rivers and the sockeye salmon O. nerka goal established for Salmon Lake/Grand Central River. Within the Kotzebue Area, the review team recommended discontinuing the Kotzebue-wide aggregate chum salmon goal and individual chum salmon goals for the Salmon, Squirrel, and Tutuksuk rivers. Additionally, revisions were recommended for the 2 remaining chum salmon escapement goals established for the Noatak and Upper Kobuk/Selby rivers. Within the Yukon Area, the review team recommended discontinuation of the Tanana River fall chum salmon goal and revisions to fall chum salmon goals for the Delta and Chandalar rivers. Within the Kuskokwim Area, the review team recommended discontinuation of the Holitna River Chinook salmon O. tschawytscha aerial survey goal and revised the existing Chinook and sockeye salmon goals for the Middle Fork of Goodnews River.

This book was released on 2006 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
