Abstract

Growth, mortality, stock and yield parameters of Nemipterus mesoprion (Bleeker), based on the data collected from 1989-’94 is reported here. The VBGF parameters in length for this species were estimated as follows. L00 = 274 mm, K = 0.7628 (annual) and t0 = -0.0011764 years. This species grows to 147, 216 and 252 mm at the end of I-III years of its life. The average total, natural and fishing mortalities were calculated as 2.55, 1.57 and 0.98 respectively. The average exploitation ratios and rates were calculated as 0.384 and 0.354 respectively. The total stock, biomass and MSY were estimated as 3991.5, 1413 and 887 t respectively. The yield per recruit study shows that it can be raised by increasing the age at first capture and fishing efforts.
