?SOME ASPECTS OF POPULATION DYNAMICS OF EXOPALAEMON STYLIFERUS FROM BANGLADESH COAST

Abstract

Elefan I and Elefan II were used to estimate population parameters inExopalaemon styliferus from length-frequency
data collected from Kutubdia channel of Bangladesh Coast. The L~and K were 11.21em and 2.20 per year respec-
tively. The annual rate of natural mortality, fishing and total mortality were 3.94, 4.57 and 8.57, respectively. The
rate of exploitation (E) was 0.54. The mean length atfirst capture (Lc) was estimated as 6.276 cm. The shrimp was
recruited in the fishery during March-May and July-October. Peak recruitment took place during April and Septem-
ber. Emax was found0.859. This studyshowssomeover fishingofExopalaemon styliferus (E> 0.50) inthe Kutubdia

totic weight was calculated as 7.889g.
