The Salmophasia fishes are included under the order – cypriniformes and belong to the family – Cyprinidae (Day, 1958). Most of the Salmophasia species are inhabitants of the tropical and subtropical waters. Man made reservoirs and lakes provide unique habitats for the fishery wealth of Karnataka. Reservoir ecosystems have been recognized for their great potential for fish production. At the present level of management, the average fish yield of Indian reservoirs is only between 10-16 kg/ha/year (Jhingran, 1991). The small reservoirs have the potential to yield more than 100-200 kg/ha. Siltation in the rivers and reservoirs, apart from diminishing the quantum of water flow results in the destruction of breeding grounds of fishes, migration of fishes and overall productivity of the reservoir. Siltation also affects the benthic population and the natural recruitment of fishes in the impounded waters. Reservoirs, like rivers are inevitably being affected by industrialization and urbanisation.
