    Abstract

    Based on the data collected from the year 1987 - 1991 the growth, mortality and recruitment pattern of eighteen species of fish, two species of cephalopods and four species of penaeid prawns have been presented in the present communication_ The total mortality coefficient, (Z) varied from lowest of 1.20 for O.cuvieri to a highest of 10.78 for P.stylifera. The natural mortality coefficient, (M) varied from 0.52 for T. thalassinus to 3.44 for S.crassicornis. The average annual yield of eighteen species of fish, four species of prawns and two species of cephalopods are 65,083, 38,404 and 11,373 tons as against the MSYof 83,023, 72,460 and 10,475 tons respectively. The MSY estimated for the total fish stock is 1,77,753t where as the present yield is 1,14,859t. This indicates that higher yield can be obtained by increasing the effort.
