Abstract

Observations on the mesopelagic fishes taken by mid water trawl in the equatorial region (lat. 03°S- 03°N to long. 76°- 86°E) are presented. The trawling operations were carried out at 12 stations at a depth range of 40-200 m where the station depth varied from 2760-3600 m. The total catch from these stations was 156.6 kg at a catch per hour of 13.1 kg. The average catch per hour was 6.5 kg from the northern side of the equator compared to a higher value of 15.7 kg recorded from the southern side of the equator. Out of a variety of mesopelagic fishes caught, the myctophids constituted 61.3 per cent and the most dominant species were Diaphus ejfulgens, Triphoturus nigrescens, Symbolophorus evermanni and Lampanyctus pusillus. Among the rest of the mesopelagic fishes Cubiceps natalensis was the dominant species. The species and size composition of the major "-onstituents are given. The need for target oriented fishing for the economic utihsation also is discussed.
