The purpose of this project is to augment the ongoing Taku Fishery Sampling and Stock Assessment in support of management as outlined in Chapter 1 of the Pacific Salmon Treaty. The Taku River sockeye salmon stock assessment project has been conducted annually since 1984 and is a cooperative effort between the Alaska Department of Fish and Game (ADF&G), Department of Fisheries and Oceans Canada (DFO), and the Taku River Tlingit First Nation (TRTFN). The objectives of this stock assessment are to provide inseason and postseason estimates of inriver abundance and to document biological characteristics (migratory timing, migratory rates, and age, sex, and size composition) of Taku River sockeye salmon stocks. Spaghetti tagged-to-untagged ratios of salmon harvested in the Canadian inriver gillnet fisheries are used to develop mark-recapture estimates of the inriver abundance of sockeye salmon.
