Abstract The susceptibility of Atlantic halibut, Hippoglossus hippoglossus (L.), to viral haemorrhagic septicaemia virus (VHSV) was tested. Juvenile halibut of approximately 5 g weight were subjected to challenge by intraperitoneal injection, cohabitation and immersion to a VHSV isolate from an outbreak of the disease in turbot, Scophthalmus maximus (L.). The intraperitoneal injection gave the highest mortality rate of 28% after 50 days. The cohabitee group suffered 19% mortality rate and the immersion group only 2%. Control groups included turbot exposed either by intraperitoneal injection or immersion which suffered mortality rates of 93 and 50%, respectively. The results suggest that halibut are markedly less susceptible to VHSV than turbot.
