Polyculture is a practice of culturing more than one species of aquatic organism in the same pond. The concept of polyculture of fish is based on the concept of total utilization of different trophic and spatial niches of a pond in order to obtain maximum fish production per unit area. Combinations of exotic and Chinese carps (bighead, silver and grass carp, common carp) are most common in Polyculture. It is an effective way to maximize benefit from available natural food in a pond. But, pond management becomes more difficult when stocking fish species having specialized feeding habits in the same pond because good fertilization and feeding practices must be followed.
