In addition, other problems such as monoculture of fish, delays in putting fish into the pond, short growing periods, and lower output and economic profits have arrested the development of rice fish farming. Recent reforms in the economic system have sparked new initiatives in agricultural production. Research suggests that rice fish culture in ditchponds can eliminate the conflicts between fish and rice and take full advantage of the symbiosis between rice and fish. Rice fish culture in a ditchpond is a three-dimensional agricultural production system. The system provides the high output of an intensive fishpond farming system and makes full use of the ecological conditions in the ricefield.
Fish feed on the abundant aquatic organisms and coexist with the rice.
Both fish and rice develop harmoniously, each promoting the growth of the other, and problems between fish-rearing and field care can be reasonably handled. Both crops can achieve their full productive potential. At the same time, liana can be grown on an awning above the pond, taro and beans can be grown on the bank, duckweed can be cultivated with the fish in the water, and loach can be grown in the mud. This integrated and intensive farming system produces higher yields of rice, fish, and vegetables. On a third of the pond, a shed with an awning is built.
