Question:

What do you understand by composite fish culture?

Answer:

Composite fish culture is a most popular technique to obtain maximum yield of fish from a pond/reservoir. The technology involves employment of compatible and non-competing fish culture through utilisation of different feeding zones of the pond or reservoir, resulting in maximum production of fish per unit area of water. It is accomplished in four steps i.e. Pre stocking, Stocking, Post stocking and harvesting.

Example: Surface feeders such as Catlas are mixed with column feeders such as Rohus, Mrigals, Grass Carp which are bottom feeders. This combination leads to an efficient utilisation of food present in the pond and enhances the yield of fish from pond.
