Abstract

Growth, mortality and yield per recruit oi Johnius dussumieri (Val.) is reported in the present communication. The VBGF parameters in length were estimated as L__ = 269 mm, K = 0.9633 year and t^ = -0.013 years. The asymptotic weight was calculated as 257 g. The mortality and yield parameters were Z = 2.38, M = 2.02, F = 0.36, E = 0.15 and U = 0.13. At the present level of F = 0.36, the yield per recruit stood at 5.46 g. It is seen that increase in the age at first capture (t^) by increasing of cod end mesh size would result in decline in the catch even at the present level of F.
