way to disinfect dead fish in fish ponds? If dead fish in fish ponds can be disinfected with quicklime. In addition, bleaching powder and chlorine dioxide are also good choices, which can destroy a large number of bacteria and fungi. It should be noted that dead fish are not necessarily caused by bacteria in the water, but may also be due to fluctuations in water quality or water temperature, or due to lack of oxygen, etc. Therefore, do not blindly disinfect, first measure the water quality, see where the problem is, and then prescribe the right medicine.
die? 1. Abnormal temperature: The reason why fish die may be caused by abnormal temperature. Because the temperature changes greatly, the fish in the middle and upper layers will also go to the lower layer. In this way, the fish below are too dense and prone to problems. In view of this situation, the water level can be increased, the water depth, the fish will not be so dense.
2. Poor water quality: Long-term poor water quality can also lead to the death of fish. Even in fish ponds, water should be changed and added regularly so as to improve water quality. It should be noted that feeding must be controlled at ordinary times, and too much irregular feeding is the main cause of water quality deterioration.
3. Severe anoxia: If the water is severely anoxic, the fish will also die. This situation usually occurs in the high temperature season, because the dissolved oxygen will decrease when the temperature is high, and the fish will lack oxygen without other means, so it is necessary to prepare a large oxygen pump to oxygenate.
