Predicted decline of protected whales based on molecular genetic monitoring of Japanese and Korean markets.
We present a two-tiered analysis of molecular genetic variation in order to determine the origins of whale' products purchased from retail markets in Japan and the Republic of (South) Korea during 1993-1999. This approach combined phylogenetic analysis of mitochondrial DNA sequences for identif...

We present a two-tiered analysis of molecular genetic variation in order to determine the origins of whale' products purchased from retail markets in Japan and the Republic of (South) Korea during 1993-1999. This approach combined phylogenetic analysis of mitochondrial DNA sequences for identification of protected species with a statistical comparison of intraspecific haplotype frequencies for distinguishing regional subpopulations or 'stocks' hunted for scientific research by the Japanese and killed incidentally in coastal fisheries by the Koreans. The phylogenetic identification of 655 products included eight species or subspecies of baleen whales, sperm whales, a pygmy sperm whale, two species of beaked whales, porpoises, killer whales and numerous species of dolphins as well as domestic sheep and horses.
