Abstract: Raising fish in paddy field has a long history in China. Based on traditional rice-fish coculture, modern integrated rice culture with fish culture develops quickly in the recent decades. Diverse models, such as rice-carp, rice-crab, rice-crayfish, rice-turtle, rice-loach, rice-snail and others, are practiced widely in rice-growing areas. New technologies for integrated rice-fish culture are gradually developed. The integrated rice-fish culture shows great effects in helping stable rice production, increasing rural income and decreasing the use of agrochemicals. Integrated rice-fish culture becomes one of the major approaches to develop green and high-quality agriculture system. The future study on integrated rice-fish culture development will focus on how the rice yield, soil fertility and environmental quality could be maintained in the integrated rice-fish systems for a long run. More detailed regional planning and a new agricultural service and technological system for integrated rice-fish culture should be developed.
