Abstract
An important threats to aquaculture is the economical looses imposed by incidences and outbreaks of infectious diseases on account of high mortality in farmed fishes and commercial aquaculture systems. Vaccination plays an important role in large-scale commercial fish farming and has been a key reason for the success of fish cultivation. Vaccination is a process by which a protective immune response is induced in an animal by administration of vaccines. Vaccines are preparations of antigens derived from pathogenic organisms, rendered non-pathogenic by various means, which will stimulate immune system of the animal to increase the resistance to the disease on natural encountered with pathogens. Fish Vaccines in general fall into three major categories namely killed whole cell vaccine, live attenuated vaccine and recombinant DNA based vaccines. Efficacy of these vaccines has been appreciably improved using adjuvants, immunostimulants and vaccines carriers. However, it is still affected by the routes of vaccine administration. In general injection is better than immersion and oral administration.
