Haidar M. A. Mazid 4200034Population parameters of Tenualosa ilisha were estimated using FISAT software with length-frequency data collected from different landing centre of Bangladesh. The von Bcrtalanffy growth parameters L∞ and K for the species were 61.50 cm and 0.83 yr1 respectively. The annual rate of natural (M) and fishing mortality (F) were found to be 1.28 and 2.01 respectively. The estimated values of the exploitation rate (E) using the length converted catch curve and Virtual Population Analysis were 0.61 and 0.346 respectively. Emax was found to be 0.697. The recruitment pattern of this species was continuous with one peak per year. The present investigation clearly showed the over fishing (E>0.50) condition for T. ilisha in Bangladesh. The estimated length weight relationship for the combined sex was found to be W = 0.01351*TL2.974.]]>Gayanilo, Jr. F.C., P. Sparre and D. Pauly,19951995Gulland, J.A.,19711971Miah, M.S. and M.
