A survey was made on trematodes of the sea fishes at Samani, southern Hidaka District, Hokkaido, during the period August 3 to 19,1970,and September 8 to 11,1971. We examined 213 fishes of 42 species, from which 4 species of 3 families of monogenetic trematodes and 35 species of 8 families of digenetic trematodes were collected (Tables 1 & 2). ZHUKOV (1960) examined the fish parasites in the sea around Putjatin Island in Peter the Great Bay and Shikotan Island of the southern Kuriles. Compared with his survey, many trematodes belonging to the cold current were common among the Hikaka area and above-mentioned two areas. A few trematodes belonging to the warm current, such as Maculifer japonicus, Opechona orientalis and Bianium hemistoma, were detected from the Putjatin area. On the other hand, such trematodes were scarecely seen from the Hidaka and Shikotan areas. Therefore, the Hidaka and Shikotan areas resemble closely each other in this regard. This fact indicates that the coast of the southern Hidaka District is greatly influenced by the cold current.
