Hybrids of goldfish and carp or koi are also
susceptible to experimental infection of KHV [8, 35]. KHV
has been detected by PCR in Russian sturgeon and Atlantic
sturgeon from fish farms in Northern Poland [44]. Susceptible
host range of KHV and its nature of infection in
different fish species are shown in Table 2. Studies also
indicate that aquatic invertebrates such as swan mussels
(Anodonta cygnea) and freshwater shrimp (Gammarus
pulex) can also act as potential vector for KHV [45]. All
age groups of carp, from juveniles upwards, are susceptible
