Since 1981, we have combined the traditional rice paddy cultivation in our country with the fish farming in paddy fields, and conducted a three-dimensional study on the symbiosis of rice, ping and fish. In this system, the use of rice paddy surface watering, Pingping feeding fish, fish manure paddy, energy flow and material exchange is reasonable, to achieve a double harvest of rice fish, a higher economic and ecological benefits, now a few The results of some studies of Paddy-Ping fish pattern over the years are summarized as follows. First, the red duckweed is a natural resource of fish Paddy fish, bait is a prominent problem, we consciously stocking and breeding red rice in the paddy field, grass carp, Nile tilapia and other herbivorous, omnivorous fish to provide
