Description	Fisheries assessment study based on the fishing activities is essential to attain reliable information for construction a management plan to achieve rational and sustainable exploitation. in the present study, spatial and landing site surveys were conducted and random fishing boats were examined to investigate their fishing gears characteristics, species composition, mean trophic level and catch per unit effort. Fishes were sampled and investigated for the gear selectivity study. The results indicate that trammel nets, gill nets and long-lines are the main fishing methods used. The lake exhibits spatial variations in its productivity and the time series of size and CPUE showed a high exploitation rate for the most important commercial fish species in the lake by the fishing gears used. Measures for fishery management based on gear selectivity are suggested for sustainability
