It is urgent to standardize the use of drugs in aquaculture

Introduction: in recent years, China's aquaculture industry has developed rapidly, especially with the decline of marine fishery resources and the continuous decline of marine fishing production efficiency, more and more fishery producers have focused on shallow water aquaculture, and even in some places there has been a situation of one-off The development of aquaculture has effectively alleviated the intensity of marine fishing, solved a large number of surplus labor, made up for people's demand for aquatic products, enriched the vegetable basket of urban and rural residents, and created great economic and social benefits However, with the development of aquaculture, its negative effects are increasingly prominent Drug abuse is one of the problems that people have to pay great attention to In order to eliminate the enemy of the cultured species, it is necessary to release the repellent drugs to the cultivation area before putting the cultured seedlings, which is called "drug Beach" It is reasonable to say that no matter what medicine is used, it should not harm aquatic resources and aquatic ecological environment But many farmers only from their own interests, regardless of the other hazards brought by drugs, resulting in more and more toxic drugs Now some places even use potassium cyanide, sodium cyanide, "dichlorvos" and "enemy kill" and other highly toxic drugs It is said that a farmer in a certain place plans to release "enemy kill" to his contracted breeding area According to the breeding area, the demand is as high as 1 ton Imagine how much damage one ton of "enemy kill" would do to the nearby sea area! If this kind of phenomenon can not be managed effectively, it will become more and more serious However, at present, there is no strict standard for aquaculture drugs Although it is stipulated in the new fisheries law that "when engaging in aquaculture production, the ecological environment of water area shall be protected, the aquaculture density shall be determined scientifically, and baiting, fertilization and use of drugs shall be reasonable, so as not to cause environmental pollution of water area" However, there is no clear regulation on what medicine can be used, what medicine can not be used, what breed of breeding should be used, etc Therefore, the author believes that it is necessary to strengthen the management of aquaculture, strictly limit the use of various drugs, establish a system of exclusive management by the competent department, and authorize the local fishery bureau to franchise, so as to control the purchase channels of aquaculture drugs At the same time, the law enforcement departments should strengthen the management of the units and individuals who operate aquaculture drugs without certificates At the same time, the state should step up the development of low harm "green" drugs suitable for all kinds of breeding Only in this way can we ensure the healthy development of aquaculture and reduce the pollution of aquaculture to the marine environment.
