Abstract/Description: | During 1964 -67, a study was made of the depth distribution of - the catfishes, Tachysurus thalassinus (RuPP -) and T. tenuispinis (Day) in the grounds up to 100 m deep in the north -western Bay of Bengal, based on the catches of exploratory trawlers. On an annual average, both species have peak abundance in two depth -ranges, the first being 30 -39 or 40 -49 m and the second, 60 -69 or 70 -79 m. Both species have high abundance in shallow grounds( < 50 m deep) in April -June and October -December and in deeper grounds in; July -September. In September -December the sizes available, of both species, increased with increase in depth. T. thalassinus of small size was recorded only from the 17»40', 19°10' and 19°40' zones. No inter -zonal difference was found in the size of the other speeies. |
