The Ministry of Agriculture and Rural Affairs issued the “Fifteenth Five-Year Plan for the Development of National Fisheries”, which mentions improving the quality of freshwater aquaculture. Accelerate the renovation and upgrading of traditional aquaculture ponds, determine reasonable aquaculture density, encourage ecological pond farming, build aquaculture tailwater facilities, achieve a “variety - yield - water treatment capacity” match, ensure that aquaculture tailwater is discharged according to standards, and explore the resource utilization of pond sediment and aquaculture tailwater. Develop modern facility aquaculture such as factory recycled water and land-based round ponds according to local conditions. Scientifically develop large-scale surface ecological fishery, promote comprehensive rice fishery cultivation in a standardized and orderly manner, develop cold-water fishery according to local conditions, and actively develop the use of saline-alkali land fishery. Optimize the farming structure and build a production layout that focuses on dominant and characteristic varieties and complements each other.
