Today, in front of the crayfish elite cooperative in Xiantai Village, Sanxianhu Town, Nanxian County, more than 200 shrimp baskets carrying crayfish are lined up one by one, forming a half-man-high white basket wall. Cao Zhengqi, chairman of the cooperative, said: "our cooperative has more than 500 shrimp farmers who raise more than 4300 mu of shrimp in rice paddies, and more than 5000 kilograms of finished shrimp are sent out today."

It is understood that Nanxian to promote the "shrimp-rice symbiosis" cultivation model, "one-season rice and two-cropping shrimp" has become a new local characteristic agricultural industry. Last year, the county raised 57000 mu of crayfish in paddy fields, producing a total of 10, 000 tons of crayfish, with a comprehensive output value of 500 million yuan and an increase of 3000 yuan per household.

Nanxian County is located in the hinterland of Dongting Lake, which is suitable for crayfish farming. In the past, many farmers used to grow single-cropping rice, and the farmland was abandoned in winter and spring. In the past two years, Nanxian County has actively promoted the "shrimp-rice symbiosis" cultivation model, that is, crayfish are raised in one-season rice fields, shrimp are "weeding, loosening the soil, and fattening" for rice, and rice is "bait, shade and avoid harm" for shrimp. With the combination of planting and breeding, in the process of crayfish growth, the rice field does not use chemical fertilizers and pesticides to produce ecological, high-quality crayfish and rice.

In order to promote "shrimp-rice symbiosis", Nanxian organized more than 30 large-scale training courses and distributed tens of thousands of relevant technical materials. The crayfish breeding and breeding base, crayfish test and demonstration base were established. More than 10 million yuan is also invested every year for village highway construction and ditch dredging projects, actively guide land transfer, develop relevant professional cooperatives, and organize and set up crayfish farming associations. At the same time, 1 million yuan of funds for accurate poverty alleviation projects in the province were used to support 400 poor households in the county to develop "shrimp-rice symbiosis". This year, the county has set up 25 crayfish cooperatives and developed more than 4000 professional households.

Crayfish produced by "shrimp-rice symbiosis" are in short supply. Customers who come to Nanxian County to buy crayfish wait in line, and rice is also sold at a good price. Chen Mingliang, president of the Nanxian Mingkang Lobster farming Association and chairman of the Liangjingyuan Ecological Agriculture Company, said that the "ecological rice" produced by the "symbiosis of rice and shrimp" in rice fields has been sold for up to 60 yuan per kilogram on the market.
