Some aspects its reproduction are studied order to provide some contribution rational sustainable management the fishery. To evaluate , sex ratio, size at first maturity, evolution sexual maturity stages gonadosomatic index (GSI) were used. The results show that ratio 46% males 54% females estuary while sea it 42% against 58% females. Size 16.2 cm for 17.5 these sizes respectively equal 17.2 18.7 males. main breeding periods during cold season hot sea. with small eggs high fecundity. absolute relative fecundity higher than
