Presently the annual fish yield from small, medium and large reservoirs is 100,75 and 50 kg/ha, suggesting substantial scope to enhance fish yield through wild capture and culture-based fisheries in these water bodies. The success of auto-stocking isvery low in Indian reservoirs, especially smaller ones, often a result of recruitment failure. Therefore, regular and sustained stocking is needed to augment fisheries in reservoirs. Stocking with the appropriate species, size (>100 mm) and at the righttime is essential to optimize fish yield from reservoirs. Production of fingerlings in cages offers the opportunity to produce fingerlings that can be used in stock enhancement programs for Indian reservoirs. Apart from raising fingerlings for reservoirstocking, cages can also be used to support production of high-value table-fish and crustaceans.
