Composite as the name suggests of different nature or variety. The same thing happens in the case of composite fish culture; in composite fish culture, five to six fishes of different species whether they are local or imported are allowed to be in a single fishpond.

Following are the two advantages of composite fish culture:

•As in composite fish culture fishes of different species are selected, they are selected on the basis that each species will have different food habits. Due to this different food habits, all the food present in the pond are consumed by different fishes.

For example- Catlas feed at the surface, Rohu feeds in the middle, Common carps feed at the bottom surface, and grass carps feed on the weeds.

•There is an increase in the yield of fish production due to composite fish culture because the competition is minimized due to different nature of different species and due to this production is maximized.
