Vivekanandan, E and Meiyappan, M M and Mohanraj, G and Nammalwar, P and Thangaraj Subramanian, V and Sarvesan, R (2000) Marine Fishery Resources off Chennai: Landings by Day and Night Trawlers. In: The Fifth Indian Fisheries Forum Proceedings, 17-20 January, 2000, Bhubaneswar, Orissa.
Off Chennai. the trawlers engaged in night fishing realised nearly 25% higher catch rate (42.4 kglh) than those engaged in day fishing (34.3 kglh) during 1996-1998. Barring June and July, the catch rate of night trawlers was higher for 10 months in a year. The day : night ratio of catch rate was very high for catfishes, rays, eels and flatfishes. On the other hand, the ratio was low for carangids, perches and squids. The die1 and seasonal vertical migration of fishes and the possibility of utilizing this information for fishing are discussed.
