Experimental susceptibility of Atlantic cod, Gadus morhua (L.), and Atlantic halibut, Hippoglossus hippoglossus (L.), to different genotypes of viral haemorrhagic septicaemia virus

Given the increasing interest in the intensive rearing of additional   aquaculture species such as Atlantic cod, Gadus morhua, and Atlantic   halibut, Hippoglossus hippoglossus, this study aimed at   investigating the susceptibility of these species to VHSV. Both   species were found to be largely resistant to VHS following   immersion challenge with a selection of 18 isolates, representing the  known marine VHSV genotypes. Only one and two VHSV-associated   mortalities occurred out of a total of 171  and 1254 halibut and   cod, respectively. These findings suggest that there is a low direct   risk to the development of commercial cod and halibut aquaculture   from the existing endemic reservoir of VHSV.     This study, coupled to field observations has, however, highlighted   the fact that both species can become infected with VHSV. The known   adaptability of RNA viruses, together with the selection pressures   associated with intensive aquaculture would thus advocate a cautious   approach to VHSV surveillance within these emerging industries.    (VHS); (VHSv); (viral hemorrhagic septicemia); (viral haemorrhagic   septicaemia); (viral hemmorrhagic septicemia)
