| Research Abstract |
On the basis of nucleotide sequences of mitochondrial genes, seven species and two species groups of dominant demersal fishes of the Sea of Japan were classified into 1)species with low genetic diversity, showing no genetic deviation of the Sea of Japan population, 2) species with medium genetic diversity species showing genetic deviation of the Sea of Japan population, 3) species with large intraspecific genetic diversity showing no genetic deviation of the Sea of Japan population, 4) species with large intraspecific genetic diversity showing significant genetic deviation of the Sea of Japan population, and 5) endemic species to the Sea of Japan. Changes of Sr/Ca values in otoliths with the growth suggested that such genetic population structures were formed through the isolation of the Sea of Japan populations during the last glacial period and the presence or absence of the ontogenetic vertical migration.
