Growth, maturity and mortality of Upeneus sulphureus from Andhra - Orissa coast

Abstract

The length weight relationship, relative condition factor, growth, maturity, mortality and exploitation ratio of Upeneus sulphureus (cuv.) from Andhra-Orissa coast were studied. Growth parameters estimated from von Bertilanfly's growth function were: La, 20.22 cm; K, 0.65846/year; and to, —0.284 years. The fish attained maturity at 131 mm and had a longevity of 4.56 years. The total mortality Z and the fishing mortality F wore estimated as 2.318/year and 0.826/year respectively. The exploitation ratio E at 0.356 indicated under-exploited state of the stock.
