Surfactants to provide a good aquaculture environment
2021-08-09 16:41:29

Modern high-density intensive aquaculture often uses fishery drugs and environmental improvers to prevent and treat aquatic animal and plant diseases, remove enemy organisms, improve the water environment and promote the healthy growth of aquaculture varieties. Such inputs mainly play a role in maintaining the relative stability of the water environment and are indispensable technical means in the process of aquaculture. The commonly used fishery drugs include pond cleaning agent, disinfection and bactericide for disease prevention and control; Algaecides and herbicides for controlling aquatic plants; Pesticides and molluscicides for pest control; Vaccines to improve immunity; As well as oxygen enhancers and sediment improvers to improve water quality and environment.

The main components of most drugs are chemical agents, including antibiotics, oxidants, complexing agents, surfactants and adsorbents. The correct and rational use of fishery drugs and environmental improvers usually will not cause harm to the breeding environment and aquatic organisms. However, due to the lack of relevant knowledge and imperfect use and management, the abuse of chemicals and antibiotics is common in the breeding process.

Studies have shown that only 20% ~ 30% of the added antibiotics will be absorbed by cultured fish, and most of the rest will enter the water environment. And antibiotics have cumulative effect. The longer the breeding time, the higher the total amount of antibiotics in water. The half-life of herbicides, pesticides and other inputs in the water body is long. Excessive use is bound to pollute the water environment, endanger the living organisms, destroy the ecological balance and harm the aquaculture water body.

If we want to effectively solve the pollution in aquatic environment, we still need to establish a perfect management system. The government should clearly point out the importance of ecological water environment, strengthen the protection of farmers, and all departments should coordinate and cooperate to fundamentally provide better protection for water quality environment and aquaculture. If we want to produce high-quality aquatic products, we need good water quality as a guarantee, so we should do a good job in water purification. Carry out reasonable and scientific planning for the aquatic environment and classify the relevant functions of the aquatic environment to ensure that the farmers can not only improve the benefits, but also reduce unnecessary pollution. At the same time, the water environment is tested irregularly to ensure the quality of the water environment, so as to provide a good aquaculture environment.
