Treatment of large yellow croaker ulcer

Treatment of ulcer of Pseudosciaena Crocea

Bacterial canker of Pseudosciaena Crocea infects fry of more than 50 grams, which can occur all the year round. The main reasons for the disease are: no obvious abnormal influence in the early stage, no feeding in the middle and later stage, often swimming slowly in the upper layer of the water body. The dorsal fin, caudal fin and caudal stalk are congested on both sides, and the fin strips are red and scattered. In severe cases, muscle bleeding and decay form hemorrhagic ulcers, and sometimes the bone tissue of the fin and caudal stalk can be seen.

Prevention: usually add drugs such as "multi-dimensional marine fish" and "Haiyuning III" to the feed, and the water is sprinkled and disinfected every 10 days with disinfectants such as "disinfectant King" or dichlorohydantoin.

Treatment: add 5 grams of "Haiyuning III" per kilogram of fresh bait + 5 grams of electrolytic vitamin 5 grams + 5 grams of allicin, mix it orally for 5 days. At the same time, the water was sprinkled with dichlorohydantoin 1ppm at flat tide, once a day for 3 times.
