抄録

Horizontal starch gel electrophoresis was used to analyze the genetical variation between Takatsu River (=stocked) and Lake Jinzai (=wild) populations of Japanese mitten crab Eriocheir japonica. Ten enzymes and 16 allozymic loci were examined using muscle, gill, and hepatopancreas tissues. Six loci, AAT-1, AAT-2, FH-2, GPI, IDHP-1, and MDH-2, were found to be polymorphic. The value of mean heterozygosity was 0.029 for the Takatsu River (=stocked) and 0.027 for Lake Jinzai (=wild) . The difference of allele frequency between these populations was not significant. Nei's genetic distance between these populations was 0.0001.These results suggest that these populations show no genetical difference at the present time.
