Fishery Management Report for Sport Fisheries in the Arctic-Yukon- Kuskokwim Management Area, 1999-2000
Report is divided into three sections. In Section I, an overview of the Arctic-Yukon-Kuskokwim Management Area is provided, including a description of the area and subareas, Board of Fish activities, and management information and activities. In Section II, effort and harvest results are presented. In Section III, more detailed summaries of major fisheries and activities are provided
Kuskokwim River Chinook and Chum Salmon Stock Status and Kuskokwim Area Fisheries: A Report to the Alaska Board of Fisheries
Conservation of Western Alaskan Salmon Stocks by Identifying Critical Linkages between Marine and Freshwater Life Stages and Long-term Monitoring
A Hierarchical Framework to Identify Influences on Pacific Salmon Population Abundance and Structure in the Arctic-Yukon-Kuskokwim Region
Information specific to recreational fisheries in the Kuskokwim-Goodnews Management Area in 2011 and preliminary information for 2012 is presented. Estimates of fishing effort, total catch, and effort is summarized through the 2011 season. This information is provided to the Alaska Board of Fisheries (board), as well as to the general public and interested parties. Summaries of major fisheries within the area are detailed, including descriptions of the performance of these fisheries, regulatory actions by the board, social and biological issues, and descriptions of ongoing research and management activities. The remote waters of the Kuskokwim-Goodnews Management Area supported approximately 22,000 angler-days of...
A Remote-Sensing, GIS-Based Approach to Identify, Characterize, and Model Spawning Habitat for Fall-Run Chum Salmon in a Sub-Arctic, Glacially Fed River
At northern limits of a species? distribution, fish habitat requirements are often linked to thermal preferences, and the presence of overwintering habitat. However, logistical challenges and hydrologic processes typical of glacial systems could compromize the identification of these habitats, particularly in large river environments. Our goal was to identify and characterize spawning habitat for fall-run chum salmon Oncorhynchus keta and model habitat selection from spatial distributions of tagged individuals in the Tanana River, Alaska using an approach that combined ground surveys with remote sensing. Models included braiding, sinuosity, ice-free water surface area (indicating groundwater influence), and persistent...
Since 1996, U.S. Fish and Wildlife Service biologists have annually used fish wheels to capture migrating adult fall chum salmon Oncorhynchus keta in the main-stem Yukon River, Alaska, and estimated their abundance via mark- recapture methods. In each year of the study, the mark rate of captured fish at a site near Rampart has been substantially greater than rates observed at numerous locations upriver of that site. The factors most likely to cause the observed reduction in the mark rate are violations of mark-recapture model assumptions or the mortality of marked fish between the Rampart site and upriver locations. Results of studies conducted through 2000 were most consistent with the hypothesis of mortality....
Country of origin provides the basis for allocating harvests of Yukon River chum salmon. The genetic divergence among Yukon River chum salmon populations adjacent to the international border as revealed by allozyme and micro satellite variation is insufficient to determine the country of origin of returning fish using mixed-stock analysis (MSA). Consequently, we investigated the resolution provided by alternative genetic markers in an attempt to detect levels of divergence that would be sufficient for MSA. We analyzed 10 Yukon River chum salmon populations for variation at 30 variable amplified fragment length polymorphism (AFLP) loci and for mitochondrial DNA (mtDNA) restriction site variation. We assessed these...
