Susceptibilities of three hybrids between crucian carp including Carassius cuvieri (Ccu), Carassius buergeri grandoculis (Cbg) and Carassius buergeri subsp.1 (Cbs) and common carp Cyprinus carpio (Cc) to KHV were evaluated in an infection experiment. ​Infection rates of KHV in each hybrid were 30% and 20% in Ccu × Cc, 40% and 30% in Cbg × Cc, and 10% and 0% in Cbs × Cc, at 14 and 44 dpe, respectively. ​This indicates that Cbs × Cc shows lower sensitivity to KHV than the other two hybrids. ​More importantly, Ccu × Cc and Cbg × Cc transmitted the virus to co-habited naïve koi.
