In the production practice of ①, the specific drugs used for disinfection should depend on the local prevalent fish diseases and drug sources; disinfection containers should be disinfected with pots, buckets, fish bags, tile tanks, etc., and metal products should not be used.

The appropriate time for ② disinfection is 8-9 pm or 3-4 pm on a sunny day; long soaking time will kill the pathogen thoroughly, but it will take a long time and lack of dissolved oxygen in water, which will cause floating head or death of fish. Therefore, in the specific operation, we should pay special attention to the dynamics of the fish. When the fish in the disinfectant can not stand it, when there is a toxic "whitening" phenomenon, the fish should be immediately put into the fish pond or increase the amount of water in the disinfectant to reduce the concentration of the solution; if the physique of the fish is weak and the water temperature is high, the washing time can be shorter, otherwise it should be longer.

③ solution should not be used for too long, otherwise it will reduce the efficacy. Do not increase the concentration of the solution at will and exceed the specified time, so as not to cause fish poisoning and death.
