Inland Fisheries

4.2.11.1 Management of medium and large reservoirs

Medium and large reservoirs are predominantly capture fisheries system and the management norms are based on the principle of stock manipulation, adjustment in fishing effort, observance of conservation measure and gear selectivity. In broad terms, management of medium and large reservoirs in India can be considered more akin to enhanced capture fisheries. Although many of them are stocked, their fisheries continue to depend to a large extent on the wild or naturalized fish stock.

i. Stock enhancement

Stocking attempts in medium and large reservoirs are successful only when the stocked fishes breed and propagate themselves.

ii. Species enhancement

It aims at augmenting the species range by adding fish species from outside with a view to colonize all the diverse niches of the biotope for harvesting sustainable crop.
