  When the aquaculture industry needs to use copper sulfate, the control of its dosage is an issue worthy of discussion. In the aquaculture industry, the amount of copper sulfate is directly proportional to the fertility of the water body, the content of organic matter and suspended solids, salinity, and pH. Therefore, when copper sulfate is used in aquaculture, it is necessary to analyze the specific situation in the pond and put in an appropriate amount.

  Because different fish has different adaptations to copper sulfate, different amounts of copper sulfate should be used in aquaculture ponds for different fish. For example, the content of copper ions in the salmon fry culture pond should not exceed 0.012mg/ L, because when this value is exceeded, the salmon fry intake is significantly reduced. When it exceeds 0.017mg/L, it will stop eating; silver carp avoids 50% of copper sulfate at 0.3ppm. Also, when the copper sulfate concentration is lower than 0.5ppm, it does not affect fish parasites, and when it exceeds 0.8ppm, it is easy to cause fish poisoning and death.

  Because copper sulfate will easily accumulate copper ions in the organism during use, it will cause kidney necrosis of fish, decrease to hematopoietic function, reduce intestinal digestive enzyme activity, and cause digestive system disorders. Therefore, the amount of copper sulfate used in aquaculture should be cautious. Before investing, you must go through detailed thinking and calculations.
