Abstract

Pathogens are always one of the threats to the aquaculture industry. Sometimes diseases can cause irreparable damage. Herpesvirus (KHVD) is one of these diseases that has affected many countries in the world, including our country. The disease only affects common carp (Cyprinus carpio) and its various breeds such as Koi fish. All age groups of common carp are susceptible to this virus. The disease occurs at temperatures above 16°C. Unfortunately, there is no specific treatment for this viral disease, and if it occurs, 80-100% of the common carp in the farm may be lost. On the other hand, fish left over from the disease are likely to carry the virus and can spread it to other groups. Fortunately, the herpes virus, which causes KHV in fish, does not cause disease in humans, so manipulating or even consuming these fish does not pose a risk to humans. Unfortunately, there is still no effective vaccine to protect farmed fish against the virus. Unfortunately, there is still no effective vaccine to protect farmed fish against the virus. Therefore, the best way to deal with it is to prevent and strictly observe the biosafety regulations in fish farms. In case of this disease, it is necessary for the breeder to inform the Veterinary and Fisheries Department in order to prevent further spread of the disease while receiving expert guidance and assistance.
