This book was released on 2022 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Yukon River Joint Technical Committee (JTC) of the United States and Canada meets twice a year to analyze and discuss harvest and escapement goals, management trends, postseason reviews, preseason outlooks, and results of cooperative research projects for Canadian-origin Yukon River salmon. This report summarizes the status of Chinook Oncorhynchus tshawytscha, coho O. kisutch, and summer and fall chum salmon O. keta stocks in 2021, presents a 2022 season outlook, and provides data about salmon harvests in commercial, subsistence, First Nations, personal use, domestic, and sport or public angling fisheries. Summaries of Yukon River research projects are also included. For 2021, the preliminary estimate of Chinook salmon (mainstem) spawning escapement in Canada was 31,452 fish, which was below the interim management escapement goal (IMEG) range of 42,500–55,000 fish. A preliminary estimate of the total Canadian-origin Chinook salmon run was 32,972 fish. The preliminary estimate of fall chum salmon spawning escapement in the Canadian mainstem Yukon River was approximately 23,170 fish, which was below the IMEG range of 70,000–104,000 fish. The preliminary estimate of fall chum salmon spawning escapement in the Fishing Branch River (Porcupine River), obtained from a weir count was 2,413 fish, which was below the IMEG range of 22,000–49,000 fish. Recommended interim management escapement goals for Canadian-origin mainstem fall chum salmon and Fishing Branch (Porcupine River) fall chum salmon in 2022 remain the same as for 2021. The JTC recommended a new escapement goal for Canadian-origin Yukon River Chinook salmon of 52,500 with an acceptable deviation range of 42,500–62,500. The Yukon River Panel will be presented with the new Chinook salmon escapement goal recommendation for consideration at their 2022 pre-season meeting.

Download or read book Yukon River Salmon Enumeration Eagle AK 2022 written by Jody D. Lozori and published by . This book was released on 2022 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both the Alaska Department of Fish and Game (ADF&G) and the Canadian Department of Fisheries and Oceans (DFO) actively manage Chinook salmon Oncorhynchus tshawytscha and fall chum salmon O. keta fisheries in the Yukon River. Alaska is obligated to manage Canadian-origin Yukon River Chinook and fall chum salmon stocks according to precautionary, abundance-based harvest-sharing principles set by the Yukon River Salmon Agreement (Yukon River Panel 2004). This negotiated agreement represents an international commitment to the restoration, conservation, and management of Yukon River salmon, and is based on escapement management . Of importance to salmon management on the Yukon River is the ability to accurately assess the numbers of Chinook and fall chum salmon migrating through the U.S./Canada border. This project employs split-beam and imaging sonar equipment on the Yukon River to generate inseason passage estimates of Chinook and fall chum salmon migrating across the U.S./Canada border. Additionally, drift gillnetting is conducted daily to monitor species composition, and to collect biological data used in characterizing Chinook and fall chum salmon runs. The project is located approximately 30 km downstream from the U.S./Canada Border (Figures 1 and 2) and is scheduled to operate continuously from approximately July 1 through October 10 annually. This project has been fully operational since 2006 (Dunbar and Crane 2007).
Download or read book Phenotypic Characterization of Chinook Salmon in the Yukon River Subsistence Harvest written by Catherine F. Moncrieff and published by . This book was released on 2005 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subsistence fishers from the villages of the lower and middle Yukon River traditionally harvest chinook salmon (Oncorhynchus tshawytscha) that they describe as whitenose, blackhead, and blueback salmon. There is speculation that these fish represent distinct runs that may include Canadian origin fish. The run and harvest timing of these types of fish are generally predictable which implies they may be different stocks. If these fish can be identified as separate stocks, direct phenotypic identification of fish stocks could prove to be a useful management tool for the subsistence fisheries with implications to direct studies in fish biology, stock status and trends, and harvest monitoring. This project incorporated traditional ecological knowledge (TEK) of the subsistence harvest with the scientific method of genetic analysis and scale pattern analysis to determine stock status. Goals of this project were to learn how Yukon fishers characterize two phenotypes of Chinook salmon and to learn through TEK specific information about each phenotype including run quality, run timing, spawning, meat quality and local uses.

The EIS examines alternative harvest strategies that comply with Federal regulations, the Fishery Management Plans for the GOA and BSAI groundfish fisheries, and the Magnuson-Stevens Act. The harvest strategies are applied to the best available scientific information to derive the total allowable catch for the groundfish fisheries.
Download or read book Subsistence Harvest Assessment and Biological Sampling of Chinook Salmon in the Togiak River Drainage written by Bronwyn Eleanor Jones and published by . This book was released on 2019 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides updated information about the harvests of salmon by the communities of Togiak and Twin Hills, Alaska, which are located in Bristol Bay in Southwest Alaska. This report details the results of a household survey administered for the study years of 2016 and 2017 for harvests and uses of wild salmon by Togiak and Twin Hills households. Also, this report includes information from in-depth interviews conducted with key respondents, as well results from chinook salmon stock composition data collection and results from chinook salmon Ichthyophonus parasite testing. As in the past, during the 2016 and 2017 study years, many residents of these study communities relied on fishing for nutrition and to support their way of life. The household surveys found that in both study years, subsistence harvests of salmon were important in both communities: approximately 70% of the salmon harvest weight for Togiak and 90% of the harvest weight for Twin Hills were caught by subsistence gillnet for both study years. Overall, 83 lb per capita in Togiak, and 44 lb per capita in Twin Hills, were harvested in 2016. Chinook salmon and sockeye salmon composed the largest portions of salmon harvests for both communities in 2016. In 2017, the harvests of salmon increased to 109 lb per capita for Togiak, but decreased to 38 lb per capita for Twin Hills. Reflecting 2016, for study year 2017 chinook salmon and sockeye salmon composed the largest portions of salmon harvests for both communities. This information was collaboratively collected by research staff of the Alaska Department of Fish and Game, Division of Subsistence and research staff from the Natural Resources Department of Bristol Bay Native Association.

Book excerpt: The Joint Technical Committee (JTC) of the United States and Canada meets twice a year to analyze and discuss harvest and escapement goals, management trends, postseason reviews, preseason outlooks, and results of cooperative research projects. This report summarizes the status of Chinook Oncorhynchus tshawytscha, coho O. kisutch, and summer and fall chum salmon O. keta stocks in 2015, presents a 2016 season outlook, and provides data on salmon harvests in commercial, subsistence, aboriginal, personal use, domestic, and sport or recreational fisheries. Summaries of Yukon River research projects and a list of 2015 Restoration and Enhancement Fund projects are also included. For 2015, the preliminary estimate of Chinook salmon spawning escapement in Canada was 83,000 fish, exceeding the upper end of the interim management escapement goal (IMEG) range of 42,500-55,000 fish. A preliminary estimate of the Canadian-origin Chinook salmon run was 87,000 fish. The preliminary spawning escapement estimate of Canadian-origin mainstem Yukon River fall chum salmon was 108,658 fish, exceeding the upper end of the IMEG range of 70,000 to 104,000 fish. A spawning escapement estimate of 20,822 Canadian-origin Porcupine River fall chum salmon was obtained from a sonar project near Old Crow. An escapement estimate for the Fishing Branch River of 8,351 fish was obtained from a weir project. This estimate was below the lower bound of the IMEG range of 22,000-49,000 fish. Recommended interim management escapement goals for upper Yukon River Chinook and chum salmon and upper Porcupine River chum salmon in 2016 are the same as for 2015.

This book was released on 2020 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological data were collected from Chinook Oncorhynchus tshawytscha and summer chum O. keta salmon along the United States portion of the Yukon River drainage in 2018. Age, sex, and length data were obtained from 4,774 Chinook and 5,907 summer chum salmon from commercial and subsistence harvests, test fisheries, and escapement projects. Samples were collected from salmon caught using gillnets, dip nets, fish wheels, beach seines, weir traps, and from hand-picked carcasses. Sex and length were recorded for nearly all salmon sampled. Ages were successfully estimated for 89% of the Chinook salmon and 93% of the summer chum salmon. This report provides a summary of the age, sex, and length data collected in 2018 for Chinook and summer chum salmon and is a single source document for historical summaries of long-term projects that collect age, sex, and length data from the Yukon Area. This report also provides a brief description of the Arctic-Yukon-Kuskokwim Database Management System (AYKDBMS) which is a publicly accessible online data archiving system that acts as an interface to query and download historical age, sex, and length data.

Download or read book Stock specific Run and Escapement of Yukon River Chinook Salmon 1981 2019 written by Toshihide Hamazaki and published by . This book was released on 2021 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a modeling framework to reconstruct the historical time series of drainagewide and stock-specific run and escapement of Pacific salmon Oncorhynchus spp. that return to a single large river system. The model combines historical data from various assessment projects that estimate mainstem passage, harvests, tributary escapements, and stock proportions under a single maximum-likelihood estimation framework. As a demonstration, the modeling framework was applied to reconstruct the historical (1981–2019) drainagewide run size and escapement of Yukon River Chinook salmon (O. tshawytscha) and each of the contributing stock components: Canada, Middle Yukon, and Lower Yukon. The model estimated that the average drainagewide (all stocks) run size was 301,000 (range: 109,000–491,000), escapement was 186,000 (88,000–305,000), and harvest rate was 35% (2–60%). The average Canada stock run size was 125,000 (39,000–214,000), escapement was 60,000 (14,000–126,000), and harvest rate was 48% (2–78%). The average Middle Yukon stock run size was 75,000 (22,000–139,000), escapement was 47,000 (14,000–126,000), and harvest rate was 35% (2–85%). The average Lower Yukon stock run was 101,000 (48,000–204,000), escapement was 78,000 (30,000–164,000), and harvest rate was 21% (1–51%). The next steps regarding the application of this model to Yukon River Chinook salmon should include a comprehensive data review, consideration of alternative model structures, and critical evaluation of model assumptions.
Download or read book Local Traditional Knowledge of the Freshwater Life Stages of Yukon River Chinook and Chum Salmon in Anvik Huslia Allakaket and Fort Yukon written by Alida Trainor and published by . This book was released on 2019 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of research conducted in 2014 on the local traditional knowledge of Chinook and chum salmon freshwater spawning and migration patterns in four Yukon River drainage communities. Researchers worked with respondents in Anvik, Huslia, Allakaket, and Fort Yukon to map environmental changes that may have affected salmon migration and spawning. Respondents interviewed for this study shared their lifetime experiences traveling, hunting, and fishing on the land and waters around their communities and shared their personal observations of change and changes they had heard of from others in their community or in neighboring communities. The study communities were chosen because of their proximity to an existing or an historical enumeration project. Proximity to enumeration projects gave researchers the opportunity to compare local observations of fluctuating salmon presence with existing data sets. Although this study intended to document possible changes to Chinook salmon spawning and migration, an abundance of environmental and ecological changes were also recorded. Over time, and especially in recent years, respondents have observed a variety of ecological changes. Some of these changes have impeded respondents' ability to participate in subsistence harvesting activities. Although more research is needed to explore each of these observations and their possible effects on Chinook salmon, it is clear that the environment that respondents are living in is rapidly changing and affecting all aspects of the natural world that they rely upon.
