Morphological and genetic differences between Japanese and Korean black rockfish Sebastes inermis were studied. To examine morphological characters, analyses of variance and t-tests of the proportion of the characters to the body were made. To examine genetic characters, horizontal starch-gel electrophoresis of isozymes were made. Many significant differences in the proportion were found between both populations, and a tendency that the proportion of the Korean population was smaller than those of the Japanese population was recognized. On meristic characters, a significant difference was found in the number of pored scales on a lateral line. However, it was suggested that these differences were not caused by genetic factors, but were caused by environmental factors, because no significant differences were detected in Adh and Gpi-2 allele frequencies
