Description 576-581
The surplus production models of Fox, Schaefer and Pell-Tomlinson with three error assumptions of normal, log-normal and gamma were used to analyze the catch and effort data of Black PomfretParastromateus niger fishery from Pakistani waters using the computer software package CEDA (catch effort data analysis).When using initial proportion of 0.4 (because the initial catch was roughly 40% of the maximum catch) the estimated maximum sustainable yield (MSY) were about 2000-2300t, the coefficient determinationR2 were about 0.20-0.31. Gamma error assumption often showed minimization failure. The estimated MSY from CEDA is smaller than most recent catch of the fishery which indicates that the fishery of P.niger in Pakistani waters may not be in a sustainable condition.
