Bath‐immunization—a practical and non‐stressing method of vaccinating sea farmed rainbow trout <i>Salmo gairdneri</i> Richardson against vibriosis

Abstract

Abstract. A non‐stressing easily applicable vaccination method against vibriosis in rainbow trout is described. The vaccine consisted of trypsin digested Vibrio anguillarum cells and was administered through a 2 h bath treatment, giving adequate protection in challenge experiments with the same V. anguillarum strain.
