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. |
