External & Internal Signs

Clinical Signs
The characteristic clinical signs of Vibriosis include red spots on the ventral and lateral areas of the fish and swollen and dark skin lesions that ulcerate, releasing a blood exudate. There are also corneal lesions, characterized by an initial opacity, followed by ulceration and evulsion of the orbital contents. However, in acute and severe epizootics, the course of the infection is rapid, and most of the infected fish die without showing any clinical signs.
