Countermeasures against viral diseases of farmed fish

摘要: Abstract Farmed fish provide an increasing fraction of the human food supply, and are major economic importance in many countries. As case terrestrial agriculture, bringing together large numbers animals a single species (i.e., monoculture) increases risk infectious disease outbreaks, including viral infections. Aquaculture, which farmed kept at high population densities close proximity with wild reservoirs, is ideal for emergence wild-type pathogens that exist benignly local and/or spreading aquatic to enter into or come net cages escaping from them. This paper provides general review nonspecialist diseases how they could be prevented treated. It has five principal objectives: (1) update on most important emerging salmonid aquaculture; (2) aspects innate antiviral defense against virus infections fish, recent advances signaling; (3) discuss current principles practices vaccinating fish; (4) drugs have activity viruses barriers employing them (5) growing use “functional feeds” aquaculture mitigate diseases. In conclusion, despite challenging environment, it expected well thought-out combinations vaccination immunostimulants solid protection fish.
