Fish farming enterprises along the Yangtze River said that the country is currently playing a series of "combination boxing" in scientific farming and water quality protection. In addition to the "Program", the state also implemented the "Ten Detailed Rules for Water", which clarified the assessment indicators of each sector. Therefore, many water surfaces are designated as prohibited or restricted farming areas. Therefore, enterprises will move to the river sections where farming is allowed, select popular fish with high economic benefits in the market, control the number of cultured fish, reduce feed, and build environmental protection facilities as required.
Ai Taoshan, director of the Fish Diseases and Water Environment Research Office of the Institute of Fisheries, Wuhan Academy of Agricultural Sciences, who was the technical general consultant of Suya Lake Ecological Aquaculture Company, said that many aquaculture enterprises are trying to develop and utilize the ecological food chain at all levels. If we choose the fish and shrimp that eat these substances according to the eutrophic substances in local waters, we can realize "clear algae and dilute fish fat" and form environmental protection ecology, ecological fishery and healthy culture from agriculture to aquatic products through material circulation. In Feng Wan Lake, Guizhou Province, where "one water connects three provinces (regions)", in view of the phenomenon of cage culture flooding and frequent illegal fishing, the local government has formulated development plans and implemented ecological farming, which has realized the integration of the first, second and third industries and the fishermen's landing to change production.
