摘　　要：About 30 million hectares of rice are cultivated annually in China(FAOSTAT,2019).Because most rice fields are wellirrigated and suitable for fish living(‘fish’here refers to various aquatic animals like carps,prawns,crabs,soft shell turtles,etc.)(Fernando,1993),many efforts have been made to determine how well rice farming and aquaculture can be coupled as a rice-fish system(RFS),of which the same land and water produces both rice and aquatic products.With the technological guidance of RFSs and political supports from the Ministry of Agriculture and Rural Affairs of China since 2010(Supplemental Table 1),multiple types of large-scale,high-efficiency and technologically intensive RFSs are now being demonstrated in the main rice-growing areas of China(National Fisheries Technology Extension Centre,2019),and in total about 1.2 million hectares of rice fields are under RFSs.
