In rice-fish farming, fish is reared in rice fields. Rice crop needs alot of water and in the starting few months inches of standing water remains in the field so rearing of fish in rice fields is very effective and beneficial. In this culture, similar land and water can be used for cultivation as well as for fish keeping. In this way, extra income can be generated through fish and the rice production is also increased to about 10 to 15 percent because the waste from fish acts as natural fertilizer for rice and it also eats the harmful pests and weeds that helps in increasing the yield of rice naturally. Promoting rice-fish culture can help farmers to generate additional income from a single piece of land.
