The use of salt and drugs to dip fish ponds, stocking, or dipping fish before shipment can not only disinfect the fish, kill pathogens on the surface of the fish, but also enhance the disease resistance of the fish. Improve the survival rate of fingerlings.
The commonly used method for fingerling dipping is: use four-tenths of salt, baking soda mixture, 10% bleaching powder, 8% copper sulfate solution or 20% potassium permanganate solution, at water temperature 10°C～25°C Diping for 10 minutes to 25 minutes can effectively control bacterial gill disease, red skin disease, hydromycosis, hair worm disease, trichoderma and so on.
When dipping, pay attention to the proportion of drug must be proportional to the proportion, not too high or too low, with the use of the distribution. The time of dipping depends on the size of the fish, its health and the temperature of the water. The species size is large, lively and healthy, the water temperature is low, and the leaching time can be slightly longer; otherwise it is shorter.
