Abstract
The study showed that the growth performance
index (F/) was 3.456. The instantaneous rates of
total mortality (Z), fishing mortality (F) and natural
mortality (M) were found to be 2.48, 1.39 and 1.09
per year respectively. The exploitation ratio (E) of
0.436, indicated that the P. niger stock was optimally
exploited in the study area and hence it can be said
that the effort should be maintained at the present
level to maintain sustainable yield.
