Copper sulphate is a common copper salt with a broad spectrum of antimicrobial effects, which can effectively prevent and improve a variety of diseases in aquaculture. However, the amount of copper sulphate must be strictly controlled, otherwise it can cause serious toxic effects to aquatic organisms. This article will introduce the correct dosage and precautions of copper sulfate in aquaculture.
1. Antibacterial effect of copper sulfate.
Copper sulfate has a broad-spectrum antibacterial effect, which can kill bacteria, fungi, protozoa and other pathogenic microorganisms in water, and effectively prevent and improve a variety of diseases in aquaculture. In addition, copper sulphate can also promote the growth and development of aquatic organisms, improving yield and quality.
Second, the correct dosage of copper sulfate.
1.Prophylactic dosage.
In the breeding process, in order to prevent the occurrence of diseases, copper sulfate can be used on a regular basis. Generally speaking, 5-10 grams of copper sulfate can be used per mu of water surface (depth of 1 meter), diluted with water and splashed throughout the pool. It should be noted that the concentration of copper sulfate should be controlled at 07-1.0ppm, otherwise it will cause toxic effects to aquatic organisms.
2.*Dosage.
When there is a disease in aquaculture, copper sulphate can be used. Generally speaking, 20-30 grams of copper sulfate can be used per mu of water surface (depth 1 meter), diluted with water and splashed throughout the pool. If the condition is severe, it can be used again after 24 hours, but the dosage should be halved. It should be noted that the ** concentration of copper sulfate should be controlled at 14-2ppm, otherwise it will cause serious toxic effects to aquatic organisms.
3. Precautions.
1.When using copper sulfate, care should be taken to control the concentration and dosage to avoid toxic effects on aquatic organisms.
2.When using copper sulfate, other antimicrobial drugs should be used in combination to achieve better results.
3.Copper sulfate should not be used with alkaline drugs, otherwise it will reduce the efficacy of the drug.
4.When using copper sulfate, attention should be paid to observing the reaction of aquatic organisms, and if there is an abnormality, measures should be taken to deal with it in time.
5.Copper sulphate should not be used for a long time, otherwise it can cause resistance to aquatic organisms.
6.When using copper sulfate, attention should be paid to safety issues to avoid harm to the human body.
In conclusion, copper sulfate is an important antimicrobial drug with a wide range of applications in aquaculture. However, when copper sulphate is used, the dosage and concentration must be strictly controlled to avoid toxic effects on aquatic organisms. At the same time, you should also pay attention to safety issues and precautions for use techniques.
