R. V. KAIYO MARU collected pelagic fishes with KYMT and ORI-200 net in the upper 100m layers of the Indian Sector of the Southern Ocean during the period from December 1983 to February 1984. More than 20 species and 150 specimens were recorded, of which the mesopelagic fishes comprised about 87% of the total catch. Differences in species composition and abundance were observed between waters north of 56°S and south of 61°S. Abundance expressed by the number of specimens per 1000m^3 water volume filtered was as high as 0.125 in the KYMT and 0.250 in the ORI-200 net in waters south of 61°S between 65 and 75°E. The area where the fish were absent agreed with the area where the cold water masses were prevailing in the waters south of 61°S in January and February 1984.
