Abstract

In an account of exploratory trawling from 1961 to 1965 on the continental
shelf along the north-western Bay of Bengal, Sekharan et al. (1968)
gave estimates of the relative abundance of cat-fishes, as a group, in the grounds
up to 100 m deep. Work on the biology of the cat-fishes of this region was
started in 1964. It was seen that the cat-fishes represented in the traWl catches
consisted mainly of two species, Tachysurus thalassinus (Rlipp.) and T. tenuispinis
(Day). The seasonal abundance, and possible annual catch, in commercial
trawling, of each species has been dealt with by the author (Sekharan,
1968). The present account deals with the catch per hour and the lengthgroups
of each species according to depth in different zones in the area, based
on the observation of exploratory trawling from 1964 to 1967.
