These white spots are white vesicles formed by parasitic parasitism, host stimulation, secretion of large amounts of mucus from surrounding tissues and proliferation of epidermal cells. If the disease is serious, the body surface tissue is destroyed. If bacteria invade, it can cause skin inflammation, scale exfoliation, fin membrane decay, split, corneal damage and blindness.

He died of being weak, swimming slowly and having difficulty breathing.

(3) the control method ① was sprinkled with 0.3 × 0.000001 sodium dichloroisocyanurate in the whole pool, which had a certain effect. ② 25 × 0.000001 formalin was sprinkled in the whole pool. After half the water was replaced the next day, the medicine was applied again. ③ washed the diseased fish with 17 × 0.000001 × 20 × 0.000001 copper sulfate for 60 minutes, once a day for 3 days.
