Research Abstract |
Nearly 100 polymorphic loci of single nucleotide polymorphism (SNP) markers have been developed besides mitochondrial (mt) and microsatellite (ms) DNA markers in chum salmon. Estimation of genetic structure in Pacific Rim chum populations and stock identification of ocean salmon were better using SNP markers than mtDNA and msDNA markers. The present study thus detailed the genetic structure of Pacific Rim chum populations, and also suggested a novel ocean distribution of Japanese chum salmon, in that they may migrate beyond 60° north in the Bering Sea.
