Aquaculture in India and other countries are moving towards intensification and the use of coastal waters for cage and pen fish farming as a result of the rising demand for food fish, the fall in capture fisheries productivity, and the exhaustion of mangrove areas available for fishpond growth. As a result of this change from low-density to high-density cultivation, the demand for feeds has increased far more than the demand for fertilizers.India's fish production has seen annual growth of more than 7%. The projected overall fisheries potential for India is 22.31 million metric tonnes, of which 5.31 million metric tonnes are found in marine fisheries and 17 million metric tonnes are found in inland fisheries. It's also significant to note that, between 2017 and 2018, 71% of the maritime fisheries potential and 58% of the inland fisheries potential have been utilized. With a combined production of more than 1.8 million tonnes, the three major carps of India-Labeo rohita, Catla catla, and Cirrhinus mrigala-contribute the largest share of production, followed by the Chinese carps-silver carp, grass carp, and common carp.
