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.
