way to disinfect the fish fry in the pond? It is best to disinfect the fish fry in the pond with povidone. This is a common drug, which has a very good disinfection effect, and if the dosage is well controlled, it will not have side effects. It is usually mixed into a solution, and then the fish is soaked in it, which can kill the bacteria and fungi on its body, reduce the possibility of disease, and prevent the occurrence of infectious diseases, and avoid a large number of fish deaths.
1. Dosage of drugs: There are many drugs for disinfection, such as quicklime, bleaching powder, etc. For different situations, the choice is also different. For example, quicklime can not be used in fish ponds, otherwise it will lead to the death of fish, and the dosage of disinfectants is also different. Changes should be made according to different situations.
2. Pay attention to phosphorus supplementation: long-term use of quicklime for disinfection will reduce the phosphorus content in water, because calcium will react with phosphorus to form phosphoric acid precipitation. Moreover, fish growth needs phosphorus, so it is necessary to measure the phosphorus content in time after disinfection, and supplement phosphorus in time if it is low.
3. Drug conflicts: There may be certain conflicts between different disinfectants. For example, bleaching powder cannot be used together with quicklime. The combination of the two will lead to failure. Usually, if acid-base disinfectants are used, it will take a period of time.
