Weir counts have been made on the Klukshu River, part of the Alsek River system, by the Department of Fisheries and Oceans (DFO) in co-operation with the Champagne-Aishihik First Nation, since 1976. A mark-and-recapture program ran from 2000 to 2004, and in 2005 and 2006, the Alsek sockeye population was estimated using tissue sample and catch information from the commercial sockeye fishery in Dry Bay as well as the weir counts. By recommendation by the Northern Fund Committee in 2008, a statistically valid sampling strategy that would provide the foundation for reconstructing sockeye and Chinook returns to the Alsek River was completed. Based on this model, it was proposed that funding be provided to analyze sockeye tissue samples collected in the commercial sockeye fishery in Dry Bay (up to 750 per season), to reconstruct the Alsek sockeye runs as described in Gazey’s analysis. The program has been running successfully each season since 2012.
