way to disinfect fish in fish ponds? If there are fish in fish ponds, chlorine dioxide can be used for disinfection. Unlike conventional disinfectants, the dosage of chlorine dioxide is very small, but the effect is very good, and the toxic side effects on fish are relatively small, so it is the best choice for disinfection. If you use it to disinfect, you usually use 0.3 mg per liter of water. It is worth mentioning that it can not only disinfect, but also increase the dissolved oxygen in the water body, which is very helpful to maintain the water quality.
are the commonly used disinfectants? 1. Quicklime: Quicklime is a commonly used disinfectant, which will become a strong alkali after entering the water, and will emit a lot of heat, thus eliminating bacteria and fungi in the water. This medicine can not be used in fish farming, but only in pond cleaning, usually about 50-80 kg per mu.
2. Bleaching powder: Bleaching powder, like quicklime, is a disinfectant used to clean ponds. However, if the dosage is well controlled, it can also be used for disinfection during fish farming. It will react with water to form hypochlorous acid and release ecological oxygen. 20 to 30 kilograms of bleaching essence is used per mu, and half of bleaching essence is used.
3. Qingtangling: Qingtangling is a highly efficient product for cleaning ponds. It can eliminate wild fish, parasites and copepods. Before using it, it needs to be diluted by 2000 times before sprinkling the whole pond. After 10-15 days of cleaning the pond, it needs to test the water. If there is no problem, the fry can be planted.
