Abstract

The growth of /. carutta can be described by the von Bertalanffy growth formula, with parameter values: L^^ - 333.3 mm; K = 0.44 per year; and t„ - —0.0002 year. The Instantaneous rates of mortality are estimated at Z = 5.07, M = 1.0 and F = 4.07. The Yield per recruit analysis shows that the yield can be increased by increasing the cod-end mesh size of the trawl nets.
