Abstract

Genetic differentiation in the intertidal goby Chaenogobius annularis was studied using allozyme markers. Samples were collected from six localities along the coasts of Japanese islands and the Korean Peninsula. Six out of 13 loci showed allelic variation in at least one population. Although the predominant alleles of 12 loci were the same among all populations, Mdh-1 showed clear differences among the populations located along the coasts of the Pacific Ocean and the Sea of Japan. These two possible geographic groups, the Pacific Ocean and the Sea of Japan groups, were characterized by diagnostic alleles of Mdh-1, namely Mdh-1 100 and Mdh-1 70.
