Abstract

During the pericxl November 1959-Ootober 1960, the Government of India trawler M. T. Ashok carried out exploratory trawling for demersal fishes, both during day and night, off the coasts of Andhra and Orissa between latitudes 17°-40' to 20°-10' N and in depths ranging from 5 to 64 metres. Six major groups of fishes viz., sharks and skates, rays, catflshes miscellaneous big and small fishes and prawns in the catches showed diurnal variations. The catches of sharks, skates, miscellaneous fish and catfish were heavier during the day than night, irrespective of the area of capture and depth. Prawns and rays, however, yielded better catches at night.
