Abstract

ELEFAN I, ELEFAN II were used to estimate population parameters in Acetes
erythraeus based on length-frequency data collected from Kutubdia Channel of
Bangladesh coastal water. The asymptotic length L and growth constant (K)
for the species were 37.00 mm and 1.20/year respectively. The annual rate of
natural mortality (M), fishing mortality (F) and total mortality (Z) were found
to be 3.61, 1.11 and 4.72 respectively. The rate of exploitation (E) was estimated
as 0.24. The mean length at first capture (Lc) was estimated as 18.206 mm.
This shrimp was recruited continuously with peak during April to June. Emax
was found to be 0.87. From the analysis, Acetes erythraeus was found to be
below optimum fishing pressure (i.e. E<0.50) in the investigated area
