Commercial Vibrio anguiliarum ‐ V. ordalii bacterin was used to vaccinate hybrid striped bass ( Morone saxatilis ♀ × M. chrysops ♂) to test the vaccine efficacy against vibriosis. Vaccination by direct immersion of fish in diluted Vibrio vaccine for 20 s resulted in increased protective immunity. The relative percent survival of hybrid striped bass challenged 35 d after vaccination was 66.7% for those challenged by 1‐h immersion exposure to 7.03 × 10 7 V. anguillarum cells/mL, 75.0% for those challenged by injection with 3.51 × 10 5 cells/fish, and 86.7% for those challenged by injection with 3.51 × 10 4 cells/fish.
