What is the mode of fish farming in rice fields in China?

China has a long history of fish farming in rice fields. Archaeological excavations and historical documents show that fish farming in paddy fields in China began at the latest in the Eastern Han Dynasty. Farmers in Bashu area keep fish in stock during the period of storing water and planting rice in summer.

In fact, rice-fish system is a typical ecological agriculture model. In this system, rice provides shelter and organic food for fish, while fish play a variety of functions, such as weeding, loosening soil and increasing fertilizer, supplying oxygen and swallowing pests. This ecological cycle greatly reduces the dependence of the system on external chemicals and increases the biodiversity of the system.

After more than a thousand years of development, a unique rice and fish culture has been formed, which not only contains rich traditional agricultural knowledge, diverse rice and fish varieties and traditional farm tools, but also forms a unique folk culture, festival culture and diet culture. Greatly enriched our traditional culture.
