As anadromous Chinook salmon Oncorhynchus tshawytscha bound for U.S. and Canadian spawning grounds migrate through the U.S. portion of the Yukon River, they are targeted by several fisheries. To fulfill treaty obligations between the two countries, fishery managers need to know what portion of fish caught in the United States are of Canadian origin. Allozyme markers have been used to assign individuals in mixed fishery samples to U.S. and Canadian portions of the Yukon River; however, these markers are limited by sampling difficulties and by the number of available loci. Microsatellite DNA markers have been considered as an alternative; however, microsatellite data are not readily transportable among laboratories...

Most information about Chinook salmon genetic diversity and life history originates from studies from the West Coast USA, western Canada and southeast Alaska; less is known about Chinook salmon from western and southcentral Alaska drainages. Populations in this large area are genetically distinct from populations to the south and represent an evolutionary legacy of unique genetic, phenotypic and life history diversity. More genetic information is necessary to advance mixed stock analysis applications for studies involving these populations. We assembled a comprehensive, open-access baseline of 45 single nucleotide polymorphisms (SNPs) from 172 populations ranging from Russia to California. We compare SNP data from...
