A disease in the koi carp (Cyprinus carpio koi) and the common carp (Cyprinus carpio carpio) caused by the herpesvirus and accompanied by a high mortality rate, has spread across numerous fish ponds all over the world since 1998, resulting mortality and significant financial losses. The herpesvirus-like virus, called the koi herpesvirus (KHV) has been isolated and identified from the koi and the common carp in the course of the incidences of massive mortalities. In the years 2004 and 2005, in Serbia, high mortality was established among one-year and two-year carp fry on three fish ponds. At two ponds, the deaths occurred among one-year and two-year carp fry during the spring period, when the water temperature was over 18 deg C. During the autumn period, mortality was recorded among one-year carp fry at water temperatures above 23 deg C. On the ground of the determined pathomorphological changes and the high mortality during the period of the year when the temperature was above 18 deg C, we suspect that KHV is also present in fish ponds in Serbia, even through the virus itself has not been isolated. The objective of this paper is briefly to present the relevant data on this disease which is inflicting significant losses to carp production, to show the current distribution of this disease, the diagnistic methods, and the possibilities for the prevention and control of KHV.
