Population dynamics, C. dussumieri, Kutubdia channel, Bangladesh coast.Abstract
Elefan I and Elcfan II were used to estimate the population parameters and length-frequency-based cohort
analysis of Coiliadussumieri,collected from Kutubdia channel of Bangladesh coastal water. The VonBertalanffy
growth parameters Leeand K for the species were 16.80 em and 1.30 year I,respectively. The annual rate ofM,F
and Z were found to be 2.49, 2.30 and 4.79, respectively. The exploitation rate (E) was estimated as 0.48. This fish
was recruited in the fishery during April-June and August-October. Peaks appeared in the months of May and
September. Ema • was found to be 0.602. From the analysis Coilia dussumieri showed below optimum fishing
pressure (i.e. E<0.50) in the coastal water of Bangladesh.
