Goldfish ulcer disease (GUD) is a bacterial disease first isolated from a goldfish farm in Victoria in 1974. Since then outbreaks have occurred at warm water fish hatcheries in NSW and Victoria. NSW DPI researchers have found that fingerlings of Murray cod, golden perch and silver perch are resistant to GUD. However, there has been one recorded outbreak of the disease in a silver perch fish farm in NSW. Trout are at high risk of infection.
