Vibriosis (Vibrio Anguillarum) as an Epizootic Disease in Rainbow Trout (Salmo Gairdneri)

Abstract

Since the first description of Vibrio anguillarum (Bergman 1909) this organism has been reported to affect a variety of salt-water fish species. In Norway V. anguillarum has never been isolated in connection with diseases in fish until 1964 when this vibrion was proved to cause mortality in rainbow trout reared in sea water. In the past 6 years epizootic outbreaks of vibriosis in rainbow trout have caused heavy losses in several salt-water farms in Norway.
