Abstract
Water resources management often requires the construction of dams across rivers for creating storages and regulating flows, which called as a sleeping giant. For easy management reservoirs of fisheries, reservoirs are generally classified as small (<1 000 ha), medium (1 000 to 5 000ha) and large (>5 000 ha) reservoirs and fish yields from different categories of reservoirs have been estimated at 50 kg/ha/yr, 12 kg/ha/yr and 11 kg/ha/yr respectively and the average yield is about 20 kg/ha/yr. Indian reservoirs have been estimated very low yield in comparison to countries such as China (>800 kg/ha/yr), Sri Lanka (>3? kg/ha/yr and Cuba (>100 kg/ha/yr) due to the poor governance, weak cooperatives, lack of fish seed for stocking, inappropriate craft and gear, poor landing and marketing channels, absence of closed season etc. For centuries, the world’s water resources have been developed to benefit mankind. The construction of dams to create reservoirs has served many purposes such as water supply, hydroelectric power, flood control, Irrigation and navigation. They are also used to regulate the flow of water in rivers. Water can be released from the reservoir during drier seasons to support wildlife and the environment downstream, and to provide a resource for human uses.
