Abstract:
Yukon River Chinook numbers have been declining and a questionable proportion of returning adults do not migrate past the border between Alaska and Canada. This transboundary tracking study uses radio-telemetry from towers and arial surveys to expand Alaska’s Chinook tagging efforts and locate the area and cause of the drop in numbers using death rate, migration speed, and timing.
