Abstract

The mortality rates and yield per recruit of the catfish, Tachysurus tenuispinis
are estimated from mean sizes and age composition. The total instantaneous
mortality rate ramges between OJ80 and 1.10. The natural mortality (M) was 0.5.1.
The yield per recruit. YW/iR was maximum when F = 0.3. As the fishing mortality
(F) already generated is considerable, caution is indicated against stepping
up the fishing effort aay further to increase the catch of th& species.
