Copper Chloride Dihydrate ( https://www.wsdty.com/product/copper-chloride-dihydrate ) dissolves in water and the free copper ions can destroy the activity of the oxidoreductase system in the insects, hinder the metabolism of the insects or combine the proteins of the insects into protein salts. At present, it has become commonly used by fishermen to kill insects and remove algae. drug. However, if it is used improperly, not only will it not be effective in killing insects and curing diseases, but it will affect the growth of the fish and even cause poisoning. Therefore, you must pay attention to the following matters when using copper sulfate:
(1) The toxicity of copper sulfate is directly proportional to the water temperature. Therefore, it should generally be used in the morning on a sunny day, and the dosage should be relatively reduced according to the water temperature;
(2) The amount of copper sulfate is directly proportional to the fertility of the water body, the content of organic matter and suspended solids, the salinity, and the pH value. Therefore, the appropriate amount should be selected according to the specific conditions of the pond during use;
(3) Use copper sulfate with caution when the water body is alkaline to avoid the formation of copper oxide to poison fish;
(4) The safe concentration range of copper sulfate for fish and other aquatic animals is relatively small, and the toxicity is relatively large (especially for fry), so the dosage should be accurately calculated when using;
(5) Do not use metal utensils when dissolving, and do not use water above 60°C to prevent loss of efficacy. After administration, oxygen should be fully increased to prevent dead algae from consuming oxygen, affecting water quality and causing flooding;
(6) Copper sulfate has certain toxic and side effects (such as hematopoietic function, feeding and growth, etc.) and residual accumulation, so it cannot be used frequently;
(7) Do not use copper sulfate in the treatment of melon worm disease and powdery mildew.
Copper sulfate poisoning mainly causes fish red blood cells and white blood cells to decrease, liver and kidney necrosis, and damage to hematopoietic tissue. Once copper sulfate poisoning occurs, fresh water should be added in time, and water quality protection antidote should be splashed throughout the pool.
