This book was released on 1997 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A workshop was held on September 16-18, 1997 in Anchorage by the Alaska Department of Fish and Game to review Pacific salmon Oncorhynchus escapement goals for major rivers in Bristol Bay. Spawner-return data were analyzed for Kvichak, Naknek, Egegik, Ugashik, Wood, Igushik, Nushagak, and Togiak Rivers sockeye salmon 0. nerka. Sockeye smolt information was reviewed for Kvichak, Egegk, and Ugashik Rivers. Available limnological and juvenile information were analyzed fiom Lake Iliarnna. In addition, spawner-return data for Nushagak River chinook salmon O. tshawytscha were also reviewed. With a few exceptions available data supported current escapement goals in Bristol Bay. Based on this most recent escapement goal evaluation, workshop participants recommended the following changes. They recommended restructuring the escapement goal policy for Kvichak River sockeye salmon to a more robust variable escapement goal. Analyses of available data were inconclusive as to whether the underlying cause of cycles in Kvichak River sockeye production were due to inherent depensatory factors or lack of spawners. The recommended policy included an off-cycle escapement range of 2-10 million sockeye salmon with a minimum goal of 2 million and an exploitation rate of 50% on runs of 4 - 20 million. The point goal for a given off-cycle year would be 50% of the inshore Kvichak run but never less than 2 million or greater than 10 million. A 6 -10 million escapement range was proposed for pre-peak and peak cycle years with a minimum of 6 million and an exploitation rate of 50% on runs of 12 - 20 million. The point goal for a given prepeak or peak cycle year would be 50% of the inshore Kvichak run but never less than 6 million or greater than 10 million. Workshop participants also recommended managing for escapements within the middle of the current escapement goal ranges for Naknek, Egegik, and Ugashik Rivers. The current management objectives or point goals for those rivers are artifacts of past Ricker stock-recruitment models and are no longer supported by the data. Therefore, it was recommended that the management objectives be changed to 1.1 million sockeye salmon for Naknek River, 1.1 million sockeye salmon for Egegik River, and 0.85 million sockeye salmon for Ugashik River. The final recommendation coming out of the workshop was that the sockeye escapement goal range for Togiak River be changed to 100 - 200 thousand sockeye salmon. Available data supported the current management objective of 150 thousand sockeye salmon for Togiak River, but indicated an escapement range of 100 - 200 thousand would on average produce higher yields.

Available in PDF, EPUB and Kindle. Book excerpt: 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 Bristol Bay. There were 13 escapement goals reviewed in the Bristol Bay management area for this review. The committee evaluated spawner-return data for all Bristol Bay sockeye salmon O. nerka and Chinook salmon O. tshawytscha stocks with escapement goals. For this escapement goal review, the committee recommends that all sockeye salmon escapement goals in the Bristol Bay management area remain the same. After the development of a run reconstruction model recommended at the last cycle, the committee also recommends no change to the Nushagak River Chinook salmon escapement goal for this cycle and that a run reconstruction-based escapement goal be considered during the next Board of Fisheries cycle.

This book was released on 2021 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.
