Data acquired through the Lower Taku River commercial and assessment fisheries are vital elements of the Taku River fishery management and stock assessment programs. Sampling involves the inspection for and recovery of coded-wire tag (CWT) information from Chinook and coho salmon which is used in the estimation of smolt production, the inspection for and recovery of spaghetti tags from Chinook, sockeye, and coho to support abundance metrics, the collection of otoliths from sockeye to estimate contributions of enhanced sockeye salmon, and the collection of age, sex, and length samples from Chinook, sockeye and coho salmon caught in the fisheries. These baseline stock assessment data are used for stock recruitment analyses, preseason forecasting programs for Chinook and sockeye salmon, and monitoring stock health.
