摘要: Genetic structure of masu salmon Oncorhynchus masou populations in Hokkaido was examined by analysing mtDNA NADH dehydrogenase subunit 5 gene (561 bp) 382 individuals collected from 12 rivers, which there were no records artificial release. Analysis molecular variance showed that between groups level and within-group explained each c. 10% genetic variance. In neighbour-joining tree, four located southern clustered into a single group; however, other did not form any clear clusters. Fu’s FS, Tajima’s D mismatch distribution test indicated sudden expansion population the entire northernmost Chiraibetsu, genetically close to group. The Sea Japan including those Hokkaido, seem have served as refugia for during glacial periods, their dispersal straying interglacial periods affected Hokkaido.
