Genetic population structure and difference of growth rate and sex ratio between local populations in Japanese flounder Paralichthys olivaceus were discussed. From mtDNA and microsatellite analyses, it was suggested that Japanese flounder from Japan Sea is not a single panmictic population. Mean growth rate of juveniles was higher in Niigata among five localities along East China Sea and Japan Sea. Sex ratios of juveniles from three localities along Japan Sea did not significantly deviated from 1:1.
