Book Description
The goal of this multi-year (1999-2002) cooperative study between the Alaska Department of Fish and Game and the National Marine Fisheries Service was to determine the migratory characteristics and escapement distribution of Yukon River chinook salmon. Primary objectives in 2000 and 2001 were to assess and refine fish capture and radio-tracking methods for a full-scale program in 2002, and to estimate drainage-wide population size using mark-recapture techniques.

Book Description
Fisheries & Oceans Canada has conducted mark-recapture studies on adult Yukon River chinook salmon since 1982. In some of these studies, up to 2,174 upstream migrants were spaghetti tagged annually at two fishwheels located just upstream from the Canada/US border. Recaptures were made in a commercial fishery upstream. This report presents results from the chinook mark-recapture program for 1990 to 1995. Background on the Yukon River, its chinook population & fishery, and mark-recapture & data analysis methods begins the report. Results are presented with regard to the biological characteristics of salmon captured, abundance estimates using three estimation methods, fishery catches & spawning escapement, harvest rates, and migration rates. The final section discusses problems with respect to the abundance estimators used and makes recommendations for further research.
