Susceptibility of fish cultured in subtropical area of Japan to red sea bream iridovirus

Abstract

Susceptibilities of spangled emperor Lethrinus nebulosus, estuary cod Epinephelus malabaricus and cobia Rachycentron canadum cultured in subtropical Japan to red sea bream iridovirus (RSIV) were studied by experimental infections. Estuary cod showed as high susceptibility to RSIV as red sea bream Pagrus major. In contrast, the susceptibilities of spangled emperor and cobia to the virus were comparatively low. The result corresponds with the occurrence of the disease in the net cages.
