Abstract:	Fish catch data were collected for' a period of 5 years (1994 to 1998) from three major lakes of Pokhara valley, Phewa, Begnas and Rupa. Catch statistics were analyzed to depict the fisheries management issues for future. Fishing gear survey interviews were conducted in 1998 to assess the degree of fishing efforts and pressure on the fish resources in the lakes of Pokhara valley. Twenty four species of fish, of which 17 native, were found in catch from the lakes of P.okhara valley. The total catch of fish was higher in lake Phewa (50. 7 t)fol/owed by lake Begnas (42.3 t) and the lowest were for lake Rupa (8.0 t) during 1998. Species contribution to the total catch of individual lakes was varied greatly. Rohu dominated in catch for the recorded lakes. Seasonal pattern of fish catch was almost similar for these lakes. About 65-70% of the total catches occurred during September to March during the year 1994-98. Growth rate of catch yield increased by 4. 3 and 6. 6% every year for lakes Phewa and Begnas, respectively for a period of 1994 to 1998 whilst the catch decreased by 10.3% every year during the same period in lake Rupa.
