During the JARE-28 cruise in the Indian sector of the Antarctic Ocean and its adjacent waters, mesopelagic fishes were collected by 10-foot IKPT at 8 stations of which 5 were located in the Antarctic, one was in the Subantarctic and 2 were in the Subtropical waters. The fishes were referred to 21 families and more than 50 species. In the Subtropical waters, fishes of the Gonostomatidae were the most abundant (85.5% of fishes caught in the Subtropical water). On the contrary, fishes of the Myctophidae tended to be numerically dominant in the Antarctic water (45.0% of fishes collected in the Antarctic water). Species compositions of catches were slightly different among three regions, the Antarctic, Subantarctic and Subtropical waters. Especially the distributions of 15 species of myctophids were clearly separable into four types.
