Dhaura reservoir are situated in between 28�53' N latitude and 79�34' E longitude in the state of Uttrakhand. The passive gear has been widely used in reservoir. Groups of fish catch composition landed by artisanal fishermen using one traditional non-mechanized craft and four types of gear: gillnets, drag net, hooks and line and cast net were studied in relation to catch contribution of major gears operated in reservoir to develop gear based management practices to obtain the sustainable yield from large water body. The present study revealed that catch efficiency of the particular gear is reflected according to the abundance and occurrence of targeted fish species, mesh size of the gear, seasons and water levels. Among the groups of fishes like major and minor carps, catfishes and miscellaneous group, the gillnet contributed maximum for the catch of major as well as minor carps followed by drag nets. The contributions from other gears like hooks and line and cast net for catfish catch were insignificant.
