This short communication describes the first isolation of the iridovirus causing the disease of redfin perch Perca fluviatilis now known as epizootic haematopoietic necrosis. Diseased fish were collected during investigations into large scale mortalities in juvenile redfin perch populations in artificial water impoundments in north-east Victoria, Australia during November-December 1984. Many fish exhibited focal hepatocellular and haematopoietic necrosis. A virus was isolated in RTG-2 cells at 15 degrees C.. Electon microscopy revealed the presence of iridovirus-like particles.
