The present study was carried out in two Stations in the Coastal areas of Khuzestan province (including Abadan, and Hendizan) using the commercial catch data collected during 2007-2008 and data on biometry of over 2300 fish. The growth and mortality parameters such asinfinite length, L_∞: 35.5, growth curvature, K: 0.56, length in zero time, t_0: - 0.32, total mortality, Z: 3.06, natural mortality, M: 1.07, fishing mortality, F: 1.99 and Exploitation ratio, E: 0.65 respectively were estimated. By using assessment methods, Y'/R = 0.019, B'/R=0.10, Exploitation rate, U: 0.61, MSY= 440 T and MCY=290 T were estimated. Exploitation ratio the Silver pomfert stock indicates over fishing and a decrease in exploitation ratio proposed.
