Vaccination plays an important role in large-scale commercial fish farming. In general, empirically developed vaccines based on inactivated bacterial pathogens have proven to be very efficacious in fish. Fewer commercially available viral vaccines and no parasite vaccines exist. Substantial efficacy data are available for new fish vaccines and advanced technology has been implemented. Fish vaccines can be delivered the same way we immunize warm-blooded animals. Fish can be immunized by immersion in vaccine for a short period of time. They can be immunized by injection, intramuscularly or intraperitoneally, and orally by mixing vaccines with feed. Vaccines have been a major factor in decreasing the use of antibiotics in aquaculture while keeping fish healthy. However, a vaccine is only effective if it is delivered properly into the fish, in the correct place and at the correct dose.
