For the purpose of obtaining basic data to understand the population dynamics of the Japanese flounder, Paralichthys olivaceus, inhabiting the Sanriku coastal waters, the concentration ratios of Ca and Sr in otoliths of juvenile fishes being cultivated for releasing to the regions, and those of adult fishes captured in both the Sanriku area (Aomori, Iwate and Miyagi) and Shizuoka prefecture coastal regions (as a comparison) were analysed using a particle induced X-ray emission (PIXE) technique. The Sr/Ca ratios of otoliths taken from juvenile Japanese flounders had significant differences between Sanriku and Shizuoka sea-farming groups. The differences in otolith Sr/Ca ratios between Sanriku and Shizuoka sea-farming stations would thus differentiate flounder populations. No significant difference in otolith Sr/Ca ratios was observed among the Sanriku group. However, the values for Aomori group formed by small fishes in the Sanriku group seemed to be lower in proportion to their body size. Therefore, genetic characteristics of the juvenile Japanese flounder being reared at the sea-farming stations in Iwate and Miyagi prefectures are possibly different from those at an Aomori station. On the other hand, statistically significant differences in the otolith Sr/Ca ratios among Aomori, Iwate, Miyagi and Shizuoka groups were found in the adult Japanese flounder. That is, higher values for the otolith Sr/Ca ratios were found in the groups inhabiting in the northern regions. The differences in otolith Sr/Ca ratios among these groups probably indicate that there are differences in the fish populations among these sample sites.
