Composite fish culture is a method of fish farming in which more than one type of compatible fish are raised together in a single pond to increase yield.
In composite fish culture, fish is selected based on compatibility and utilization of available fish food organisms in all the natural niches.
The common fish species groups are Catla (Surface feeder), Rohu (Column feeder) and Mrigal (Bottom feeder); Silver Carp, Grass Carp and Common carp.
Composite fish culture helps farmers to utilize all the space available in the pond efficiently.
Practicing this fish culture system helps to achieve optimum feed utilization as feed gets completely consumed by different fish species and does not get wasted.
Due to maximum utilization of the available space, total fish yield increases in composite fish culture.
Raising various fish species helps farmers to supply fish to the market according to the market demands, hence ensuring profit in most of the seasons.
Composite fish culture is highly profitable as all the layers of the pond is utilized, hence farmer get to sell more amount of fish to the market from the same area.
