Title : Introduce of most important Aquatic Vaccines in Aquaculture and Marine Fish
Abstract:
This fact is well known that the appearance and development of all fish disease process could be the result of the interaction between three parameters such as pathogen, host, and environment. Therefore, only multidisciplinary studies involving knowledge of the characteristics of the potential pathogenic microorganisms for fish, aspects of the biology of the fish hosts, as well as a better understanding of the environmental factors affecting them, will allow the application of adequate measures to prevent and control the main infectious diseases limiting the production of freshwater and marine fishes. Vaccination is becoming an increasingly important part of aquaculture, since it is considered a cost effective method of controlling different threatening diseases. Also, it was alternated for Antibiotic application in some developed countries and it could be positive aspect to decreasing antibiotic resistance in some familiar pathogens in the environment and aquatic ecosystems. The term vaccination strategy has been defined to include the decision as to which diseases to vaccinate against, as well as the vaccine type, vaccination method, the timing of vaccination and the use of revaccination. In this lecture most important aquatic vaccines such as Bacterins, Live attenuated vaccines, killed vaccine and DNA vaccines would be discussed for some important fish bacterial and viral diseases. Also, monovalent and polyvalent and route and strategy of administration fish vaccines would be talked. Meanwhile, economic aspects related to fish vaccination, potential costs and benefits could be discussed.
