Technical Abstract: Infectious diseases are a major worldwise cause of economic loss in the farming of intensively cultured fish. The treatment of infected fish with antibiotics should be considered only in emergencies, or in the absence of vaccination, because such treatment is often ineffective and costly. Management of diseases of farmed fish requires strategies to prevent infection as well as to rapidly detect pathogens in fish without signs. Vaccination is a safe and effective means of preventing diseases in intensively cultured fish. However, vaccine strategies for management of fish diseases needs to be part of a preventive health management practice. This paper will discuss the latest advances and strategies for the vaccination of fish, especially against economically important pathogens of tilapia, catfish, trout and hybrid striped bass. These topics will include killed and modified live vaccines. Routes of administration by injection, immersion, oral and in ovo delivery of vaccines, safety and immunostimulation of vaccine responses with particular emphasis on a vaccine against Streptococcus iniae in tilapia and other species of fish will be presented.
