Disease control techniques of moustache catfish culture

In the process of bearded catfish culture, disease prevention is particularly important. In the daily management work, the fish must be disinfected when the fry is put in. Common salt mixed with water at 1:30, that is, 1 kg of salt with 30 kg of water, soak the fry before entering the pond for 20 minutes before releasing the fry. When the fry goes into the pond, the transported fry will have the symptom of "spasm" because of the big difference in the temperature of the pond water. Before the fry goes into the pond, the pond water must be slowly flushed into the bucket in which the fry is transported, so that the water temperature can be slowly balanced before the fry can be released into the pond.

After the fry is put into the pond, the feed and breeding feed change, and intestinal diseases often occur within a few days of stocking, resulting in a large number of dead fish. Therefore, from the first feeding after seedling release, 610g erythromycin was mixed into 1kg feed, once a day for 5 consecutive days.

Viral rotten skin disease beard catfish culture is the most harmful disease, the disease mostly appears after one month of fry stocking, when the weight is about 50 grams. The treatment is shown as follows: blisters appear on the body surface of diseased fish, hyperemia at the base of fins, decay, and in severe cases, systemic ulcers, and a large number of dead fish will appear until the whole army is wiped out. Prevention and treatment: sprinkle the whole pond with quicklime regularly, using 10-15 kg of lime every 667 square meters for 15 days. If the occurrence of this disease, most of the disease can not be controlled, the disease only in the daily management of regular medication, do a good job of prevention.
