Applicants will use radio telemetry techniques and a mark-recapture model to estimate total abundance, stock composition, run timing, migration characteristics, and spawning distribution of chinook salmon in the Yukon River. The Alaska Department of Fish and Game (ADF&G) and the National Marine Fisheries Service (NMFS) began this project as a feasibility study in 2000 and 2001 to address technical aspects and logistical considerations associated with a large-scale basinwide telemetry program. A full scale, basinwide radio tagging and monitoring program was conducted in 2002 that included a significant element independently funded and operated in the Canadian portion of the drainage. This proposal represents a continuation of the 2002 program for an additional year in the absence of federal fishery disaster relief or treaty implementation funding.
a) Estimate stock composition (proportional distribution) of the total chinook salmon return among major tributaries.
b) Estimate stock specific run timing, migration rates, and migration charactaristics.
c) Estimate the abundance of chinook salmon in the Yukon River drainage upriver of Russian Mission with relative precision (coefficient of variation) less than 20%.
