註釋Chinook salmon support important commercial, sport, personal use, subsistence, and educational fisheries in Cook Inlet, Alaska with annual harvests that can exceed 90,000 fish. Many populations contribute to these harvests, which often occur in areas where stocks intermingle, so the exploitation and productivity of individual stocks are not well known. This lack of knowledge compromises both protection of stocks from overharvest and utilization of stocks with fish in excess of spawning needs. Genetic analysis, using single nucleotide polymorphism (SNP) technology, can discriminate among discrete fish stocks in fishery samples if adequate stock structure exists. Here, we update a peviously reported baseline of 30 populations using 46 SNP markers with an additional 25 populations and a subset of 42 SNP markers to determine population structure and test potential reporting groups for mixed stock analysis (MSA). After nearly doubling the number of populations in the baseline, southern region stocks continue to have greater genetic diversity than northern region stocks.
