Is there any legal basis for banning fertilization in fish farming?

It is prohibited by law to fertilize fish in reservoirs. Fertilizing fish in reservoirs leads to water pollution, deterioration of water quality, and affects the people's production and living water. In order to strengthen water quality management, protect our county's limited reservoir water resources, and control man-made reservoir water pollution from the source, in accordance with the "Environmental Protection Law of the People's Republic of China" and the "Water Pollution Prevention and Control Law of the People's Republic of China" ", the "Fisheries Law of the People's Republic of China", the "Aquaculture Quality and Safety Management Regulations" of the Ministry of Agriculture and other relevant laws and regulations on "It is strictly prohibited to pollute drinking water sources" and "Whoever pollutes shall be responsible for the treatment in place". , after research by the county government, it was decided to ban the use of chemical fertilizers and livestock and poultry manure for fish farming in small and medium-sized reservoirs in the county.
