Cultured fish species affected by red sea bream iridoviral disease from 1996 to 2000.
Occurrences of red sea bream iridoviral disease (RSIVD) in cultured marine fish were investigated by our diagnostic works and by collecting information from prefectural fisheries research stations. The infection was identified by using indirect immunofluorescence test with a monoclonal antibody against red sea bream iridovirus (RSIV). In total, RSIVD was confirmed in 29 cultured marine fish species from 1996 to 2000. After 1995, 11 fish species were newly confirmed as susceptible hosts to RSIV. Since the first occurrence in 1990, RSIVD has been recorded in a total of 31 cultured marine fish species in 18 prefectures located in south-western part of Japan.
