Species of fish affected and geographical distribution

Grass carp haemorrhagic disease affects young fish and yearlings of grass carp (Ctenopharyngodon idella) and of black carp (Mylopharyngodon piceus). It is widespread in the southern regions of mainland China and causes severe, economically devastating losses for the largest national aquaculture production in the world. Mao et al. (1988) reported mortality rates of 50-70% in yearlings. Gudgeon (P. parva) and Gobiocypris rarus (Wang et al., 1993, 1994) are susceptible to experimental infection. The disease is not registered outside mainland China.
