8-hydroxyquinoline Copper is one of the commonly used and effective drugs in aquaculture, but it is also one of the more risky drugs.
8-hydroxyquinoline Copper is one of the commonly used and effective drugs in aquaculture, but it is also one of the more risky drugs. There are certain disputes in the industry. Some people advocate that copper sulfate should not be used. The reason is that copper sulfate is a heavy metal substance and has certain residues. Sex is harmful to people. However, there is no "prohibited" provision in the law, indicating that it is still a legally used drug input category, but it only emphasizes that the withdrawal period of copper sulfate should be strictly followed. Of course, copper sulfate is an extraordinary special drug substance, and it must be used with caution in production. Otherwise, it may lead to phytotoxicity accidents or even serious residues accumulated in the fish body, causing unnecessary injury (damage). Therefore, sulfuric acid Although copper is not banned, it should be used with caution!

   Copper sulfate is an inorganic compound, blue sail, stone gall, and its chemical formula is CuSO4. Anhydrous copper sulfate is an off-white powder, which easily absorbs water and turns into blue copper sulfate pentahydrate CuSO4.5H2O

Copper sulfate is a heavy metal salt. Its hydrolyzed copper ions (Cu2+) can combine with proteins to form protein salts. Copper ions can also form complexes (chelates) when combined with proteins, which can denature and precipitate proteins, thereby causing parasites. Enzymes of insects lose their activity, which has the effect of killing parasites, especially for protoparasites, and has a strong killing effect on protozoa and low-grade algae with colloids. Therefore, it is one of the commonly used drugs in the prevention and treatment of fish diseases, and its efficacy is very good. It can treat and kill the protoparasitic diseases of fish, such as ectoparasitic flagellates, ciliates, flukes, sinensis, etc. Algae plants in water bodies are also lethal.

   Basic Copper Chloride, the safe concentration range used is very small, and the efficacy is greatly affected by environmental factors, so the phenomenon of drug damage during the use or the effect of the drug is not obvious. The main factors affecting the toxicity and safe concentration of copper sulfate are: pool water temperature, hardness, pH, and organic content.
