Stock status of Fraser River sockeye / A. Cass … [et al.].: Fs70-1/2000-068E-PDF

Fraser River sockeye provide the backbone of the commercial fishing industry off Canada’s west coast. They also have profound social importance to coastal communities and indigenous peoples living in the Fraser River watershed. Over 150 stocks can be identified by spawning location and adult migratory timing patterns. Most Fraser River sockeye stocks are still recovering from catastrophic mortality inflicted early in this century from river blockages and overfishing. With ratification of the Pacific Salmon Treaty between Canada and the U.S. in 1985, management of Fraser River sockeye fisheries has been regulated by the Fraser River Panel under the auspices of the Pacific Salmon Commission. Fraser sockeye are currently managed to stock-specific target numbers of spawners (spawning escapement) and surplus harvest. Since the Treaty was ratified, spawning escapement goals have been set annually by Canada. The first section of this report describes the data and data sources used in this analysis. The second section describes DFO rebuilding policies initiated in 1987, and reviews production trends for 11 stocks. The third section presents a stock-recruitment analysis of each stock using a Bayes perspective to capture uncertainty.
