Available in PDF, EPUB and Kindle. Book excerpt: In 2015, the Alaska Department of Fish and Game (ADF&G) used dual frequency identification sonars to estimate an escapement of 1,709,051 (95% CI: 1,708,905 - 1,709,197) sockeye salmon (Oncorhynchus nerka) into the Kenai River, and 470,677 (95% CI: 469,545 - 471,808) sockeye salmon into the Kasilof River. Fish wheel sampling determined that predominant age classes for sockeye salmon in the Kenai River were 1.2 (18.6%), 1.3 (47.5%), 2.2 (6.7%), and 2.3 (26.2%); Kasilof River 1.2 (21.0%), 1.3 (34.7%), and 2.2 (35.1%); Yentna River 1.2 (18.9%), 1.3 (62.3%), and 2.3 (9.5%). Length and sex ratio information were also collected for sockeye salmon at each river. Results of escapement projects conducted by other agencies and organizations are also briefly mentioned in this report.

Available in PDF, EPUB and Kindle. Book excerpt: In 2014, the Alaska Department of Fish and Game used dual-frequency identification sonar to estimate an escapement of 1,520,340 (95% CI: 1,494,105-1,546,575) sockeye salmon (Oncorhynchus nerka) into the Kenai River, 440,192 (95% CI: 438,380-442,003) into the Kasilof River, and 55,759-137,256 into the Yentna River. Escapement estimates for the Kenai River were adjusted postseason relating to an overlap of sockeye and pink salmon. An escapement range for the Yentna River was estimated postseason for sockeye, pink (O. gorbuscha), chum (O. keta), and coho (O. kisutch) salmon from 6 sets of fish wheel selectivity indices obtained from the literature. The predominant age classes for sockeye salmon in the Kenai River were 1.2 (12.3%), 1.3 (63.5%), 2.2 (7.2%), and 2.3 (15.3%); Kasilof River 1.2 (42.4%), 1.3 (29.4%), and 2.2 (20.6%); Yentna River 1.2 (39.4%), 1.3 (33.3%), 2.2 (12.4%) and 2.3 (10.2%). Length and sex ratio information were also collected for sockeye salmon at each river. Results of escapement projects conducted by other agencies and organizations are also briefly mentioned in this report.

This book was released on 2016 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the status of activities associated with legislative increments directed at Cook Inlet coho Oncorhynchus kisutch and sockeye O. nerka salmon genetic studies conducted by the Division of Commercial Fisheries Gene Conservation Laboratory and Central Region staff. The coho salmon study involved 3 investigative phases. In Phase I, analysis of existing samples indicated that sufficient population genetic structure exists among populations of Cook Inlet coho salmon to warrant construction of a full genetic baseline for genetic stock identification. In Phase II, development of the genetic baseline indicated 8 potential genetic reporting groups for genetic stock identification of Cook Inlet coho salmon fishery samples. The final report for Phase II will be published in the spring of 2016. In Phase III genetic stock identification was used to estimate the stock composition of harvests in test and commercial fisheries of Cook Inlet for the 2013-2015 seasons. Results from these analyses will be used to determine spatial and temporal distribution of coho salmon in the offshore test fishery and commercial harvest and to estimate the total harvest of selected stocks in the commercial salmon fisheries. During this period over 23,000 samples were collected for analysis from the Central District drift gill net fishery, Upper subdistrict set gillnet fishery, General and Eastern subdistrict set gillnet fisheries, and the northern and southern offshore test fisheries. The final report for Phase III is expected to be completed by the end of summer 2016. A fourth study, for sockeye salmon, will analyze the DNA from archived scales to retrospectively estimate historic stock compositions of Cook Inlet harvests. This is the third year of that 5 year project in which the laboratory will reconstruct escapement and total runs of sockeye salmon for Susitna River and the major systems in Upper Cook Inlet.

This book was released on 2014 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska State Legislature requested a status report to the Finance Committees describing work by the Alaska Department of Fish and Game in Cook Inlet on escapement monitoring, genetics baseline data, mixed stock sampling, smolt out migration, migratory studies and habitat improvements for Chinook, coho, and sockeye salmon. This report summarizes the status of activities associated with legislative increments directed at Cook Inlet coho and sockeye salmon genetic studies conducted by the Division of Commercial Fisheries Gene Conservation Laboratory and Region II staff. For Cook Inlet coho salmon, project updates for three investigative phases are provided. In Phase I, analysis of existing samples indicated that sufficient population genetic structure exists among populations of to warrant construction of a full genetic baseline for genetic stock identification. Phase II describes the status of the genetic baseline following the second year of sampling when 3,319 fish were collected. Preliminary results using samples through 2013 indicate at least five genetic reporting groups are feasible and that additional baseline collections are be necessary before genetic stock identification can be effectively applied to Cook Inlet fishery samples. Phase III describes the status of genetic stock identification of harvests in test and commercial fisheries of Cook Inlet for the 2013-2015 seasons. To date, over 16,000 samples have been collected for future analysis from the Central District drift gill net fishery, the General and Eastern subdistrict set gill net fisheries, and the northern and southern offshore test fisheries. For sockeye salmon, we summarize the status of a project to analyze DNA from archived scales as a means to retrospectively estimate stock composition in historic Cook Inlet harvests. This is the second of a five-year project that will reconstruct Susitna River sockeye salmon escapement and total runs for the major systems in Upper Cook Inlet.
