抄録

The chum salmon populations collected from 21 rivers in Japan were analyzed by using as markers the three genes, Idh-A2, Idh-B2, and Ldh-Al, controlling IDH and LDH isozymes.<br> (1) No differences in gene frequencies at the three loci were found between the sexes or between the years of catch.<br> (2) Any two of the 21 river populations showed clear differences of gene frequencies, indicating that they are independent of each other.<br> (3) The chum salmon populations in Japan could be divided into at least 3 groups: Hokkaido group, and the Pacific Ocean and Japan Sea groups of Honshu.<br> (4) A geographical cline of gene frequencies was observed in each of the Pacific Ocean and Japan Sea groups of Honshu, the phenomenon suggests that there has been a mixing of chum salmon individuals between neighboring rivers, though on a small scale.
