Aquaculture systems range from very extensive, semi-intensive and highly intensive to hyper-intensive. Aquaculture systems range from traditional earthen pond to an intensive bio-secure indoor system monitored with high-tech equipment. Based on the availability of the local resources, socio economic conditions as well as regional requirements, different systems of fish farming were being developed. Recirculatory aquaculture system (RAS), biofloc based system and aquaponics are some of the widely recommended fish production systems while ensuring greater water productivity. Research is being carried out to standardize these technologies for culture of the Indian species.
