Abstract

Value of length growth parameters Loo, K and t 0 from age-length
relation obtained from length-frequency analysis for the soldier catfish
stock were estimated to be 47.6 em, 0.51 per year and 0.03 year respectively.
The age at recruitment (tr) ws 0.58 year and the age at first capture (tc)
0.83 year. The total mortality (Z) was 0.88 including the present natui·al
mortality (M) of 0.84 and fishing mortality (F) of 0.04. The total stock of
this fish along the Northwest coast of India was assessed to be 32,413
tons and the MSY 5,426 tons which is much higher than the current catch
of 863.8 tons. The potential yield (P Y) of 38.7 g per recruit could be obtained
at the optimum of exploitation (ty) of 2.84 years.
