Rice-fish farming landscape in Arunachal Pradesh, Northeast India. Net gains vary between and within countries. Overall, integrated rice-fish fields have a positive impact on net returns. In Bangladesh, net returns are over 50% greater than in rice monocultures. [6] In China, the net return by region is between 45 and 270% greater. [6]
Chinese Rice Fish have been utilized in China and Asia for hundreds of years for rice farming. [6] This process allows the fish to provide protein to the rice, enhancing the food. It is proven that in the presence of rice fish, rice fields grow better, and the rice yield is increased by approximately 4–15%. [7]
Rice polyculture is the cultivation of rice and another crop simultaneously on the same land. The practice exploits the mutual benefit between rice and organisms such as fish and ducks: the rice supports pests which serve as food for the fish and ducks, while the animals' excrement serves as fertilizer for the rice.
The Japanese rice fish (O. latipes), also known as the medaka, is a popular model organism used in research in developmental biology. This species has traveled into space, where they have the distinction of being the first vertebrate to mate and produce healthy young in space. [6]
The Khazan is a traditional farming system of Goa, India.It comprises mainly rice-fish fields established on reclaimed coastal wetlands, salt marshes and mangrove forests.It involves construction of levees and sluice gates to prevent sea water from entering the fields.
Ducks with free access to rice paddies in Bali, Indonesia provide additional income and manure the fields, reducing the need for fertilizer. [25] In South-East Asia and China, rice-fish systems on rice paddies have raised freshwater fish as well as rice, producing a valuable additional crop and reducing eutrophication of neighbouring rivers.

Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures. It was spread in prehistoric times by the expansion of Austronesian peoples to Island Southeast Asia, Madagascar, Melanesia, Micronesia, and Polynesia.
