Globally Important Agricultural Heritage Systems (GIAHS)

Rice Fish Culture, China

GIAHS since 2005

In Asia fish farming in wet rice fields has a long history. A Chinese clay plate dating to the Han Dynasty 2000 years ago shows a fish swimming from its pond into a rice field.

Ecological symbiosis exists in the traditional rice-fish agricultural system: fish provides fertilizer to rice, regulates micro-climatic conditions, softens the soil, disturbs the water, and eats larvae and weeds in the flooded fields; rice provides shade and food for fish.

Furthermore, multiple products and ecological services from the co-ecosystems are beneficial to local farmers and the environment. The high quality food of fish and rice are helpful to maintain farmers’ nutrient and living standard: the reduced cost and labor increases the productive efficiency, and, especially by reducing the use of chemical fertilizers, pesticides and herbicides for insect and weed control, helps in agro-biological conservation and field environmental protection. The rice-fish system in Longxian village of Zhejiang province demonstrates an ingenious approach to generating ecological, economic and social benefits through encouraging essential ecological functions.

Rice-fish Culture System

Rice-fish culture has great potential for being developed in countries with vast areas of irrigated rice fields. Standing water in rice fields promotes the development of a teeming ecosystem with aquatic animals such as fish, ducks, freshwater prawns, marine shrimps, crayfish, crabs, turtle, bivalve, frogs, snails and even insects.
