The soluble channel catfish virus (CCV) envelope was harvested and used as a vaccine for channel catfish virus disease. Three‐ to four‐day‐old eggs of channel catfish Ictalurus punctatus and 1‐week‐old fry were vaccinated by immersion. A booster was given to subgroups of fry 2 weeks after vaccination. Vaccinated and nonvaccinated control groups were challenged with viable CCV 8 weeks after vaccination. All challenged nonvaccinated control fry died during the first experiment, and 56% died in the second experiment. Survival offish vaccinated as eggs or fry was 31 and 82%, respectively; survival of groups given a booster dose was 81 and 89%, respectively.
