Symptoms and Prevention and Treatment Methods of Vibriosis in Salmon and Trout
Symptoms include exophthalmos (bulging eyes), hemorrhage, and muscular hemorrhages that resemble burns, with swelling, erosion, and necrosis of the affected areas. Hemorrhages occur at the fin bases, body surface, mouth, and anus. The intestines are congested, inflamed, and lose their elasticity. Blood spots appear on the liver, the spleen is enlarged, and the kidneys are swollen. For prevention, sulfonamide drugs are mixed into bait and fed at 75 mg to 100 mg per kilogram of body weight for 1 consecutive week, with the dose doubled on the first day; furazolidone is mixed into the feed at 0.1 percent and fed for 1 consecutive week.
