Polyculture in aquaculture refers to the cultivation of more than one species of fishes in the same pond. The main objective behind polyculture is that the production of fishes in ponds can be increased by raising a combination of species having different food habits. It involves the effective use of fish foods available in the pond, where the wastes produced by one species may serve as inputs for the other.
