Stock Assessment and Management of Tenualosa ilisha in Bangladesh

Abstract

The stock assessment of Tenualosa ilisha of Bangladesh water is studied using length based analysis to evaluate growth parameters, mortality rates, exploitation rate, maximum sustainable yield (MSY) and the corresponding fishing pressure. The study reveals that the fishery is harvested at a higher level than the optimum fishing pressure. This fishing pressure may be reduced near to 1.76/yr i.e., 21.08% from the present level of 2.23/yr, to obtain an average MSY of 1,65,271 t.
