Aquaculture should promote harmless disinfection
In recent years, the aquaculture industry in China has developed rapidly. With the continuous adjustment of fishery production structure, aquaculture development has broad prospects. However, for the time being, disinfectants for aquaculture have become a big problem that cannot be ignored. Due to the non-standard aquaculture drugs, many farmed areas have caused great harm and incalculable economic losses to the waters involved. At the same time, it also triggered a lot of breeding species poisoning disputes. Recently, the author learned a lot of similar incidents in the investigation, but fortunately, in front of a large number of facts, many farmers have realized the danger of drug abuse and strengthened the dredging and detoxification of fish ponds. That is, prior to the release of the cultured seedlings, the sludge deposited in the culture tank (field) is removed, and then the bottom of the tank is air-dried to achieve the purpose of disinfection and detoxification. It is understood that this method works well and not only can effectively eliminate the germs that endanger the cultured species, but also adopts the method of network filtration when water is contained. It can also prevent the entry of natural enemies and ensure the healthy breeding of aquatic products. However, due to the relatively large investment in the dredging and detoxification method and it is rather troublesome, this method has been implemented better and adopted more often by some established old farmers. For some temporary farmers, because there is no long-term plan, the application of pesticides is still used to save investment, and the use of drugs is not standardized. From this point of view, all localities must have unified plans for the development of aquaculture and make long-term plans so that the aquaculture industry in China can continue to develop healthily.
