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.

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. 

Following picture represents the composite fish culture and different nutritional habits of fishes:
