What are the precautions for disinfecting fish species? These points you need to know

① In production practice, the specific drug used for disinfection depends on the fish diseases prevalent in the local area and the availability of the drug; the disinfection containers should be wooden basins, wooden buckets, fish bags, clay jars, etc., and metal products should not be used.

② The disinfection time is best chosen at 8-9 pm or 3-4 pm on a sunny day; a long soaking time kills pathogens more thoroughly, but if the time is too long and the dissolved oxygen in the water is insufficient, it will cause fish to gasp at the surface or die. Therefore, during the actual operation, special attention must be paid to the behavior of the fish. When the fish in the disinfectant solution cannot endure it and show signs of poisoning such as "turning white belly up," the fish should immediately be placed into the fish pond or water should be added to the disinfectant solution to reduce the drug concentration; if the fish species are weak and the water temperature is high, the soaking time can be shorter, otherwise it should be longer.

③ The medicinal solution should be prepared and used immediately and must not be left standing for too long, otherwise the efficacy of the drug will be reduced. Never arbitrarily increase the concentration of the medicinal solution or exceed the specified time, so as to avoid poisoning and death of the fish species.
