| Research Abstract |
In order to utilize the parasites as biological tags to study the ecology of marine fishes for stock enhancement, the ecto- and endoparasite fauna was studied for red seabream Pagrus major, black seabream Acanthopagrus schlegelii, and rockfish Sebastes spp. in Japanese waters, especially in the Seto Island Sea. By comparison of the ecto- and endoparasite fauna between six regions in the Seto Island Sea, this study has revealed hat 1-year red sea bream consist of several local stocks there. The population of black seabream was differentiated, based on the endoparasite fauna, into some stocks in coastal waters around Japan.
