Abstract: 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 com-positions of catches were slightly different among three regions, the Antarctic, Subantarctic and Subtropical waters. Especially the distributions of 15 species of niyctophids were clearly separable into four types.
