A rice-fish system is a rice polyculture, a practice that integrates rice agriculture with aquaculture, most commonly with freshwater fish. It is based on a mutually beneficial relationship between rice and fish in the same agroecosystem .
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.
Rice-duck farming is the polycultural practice of raising ducks and rice on the same land. It has existed in different forms for centuries in Asian countries including China, Indonesia, and the Philippines, sometimes also involving fish .
Polyculture is the growing of multiple crops together in the same place at the same time. It has traditionally been the most prevalent form of agriculture. [1] Regions where polycultures form a substantial part of agriculture include the Himalayas, Eastern Asia, South America, and Africa. [2]
IMTA is a specialized form of the age-old practice of aquatic polyculture, which was the co-culture of various species, often without regard to trophic level. In this broader case, the organisms may share biological and chemical processes that may be minimally complementary , potentially leading to reduced production of both species due to ...
It is possible to farm it in 100% seawater and directly connect its cultivation system to an aquaculture system for a wide range of fish species. [2] Common ice plant is known to accumulate high levels of heavy metals when grown in soil. This new system enables the farming of safe-to-eat organic ice plant by removing it from this environment.

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.
In this system, ducklings are introduced into rice paddies for the purpose of (1) providing natural fertilizer, (2) to strengthen the rice seedlings by oxygenating the water from the turbulence caused by the ducklings' swimming actions, as well as (3) to weed and eat insects. One season, disease destroyed Furuno's entire crop.
