The virulence of different VHSV strains to different fish species varies, and rainbow trout Oncorhynchus mykiss is regarded as one of the most susceptible species. The presence of VHSV in wild fish has been considered as a threat to the salmonid farming industry. The recent outbreak of VHS in sea farmed rainbow trout in Western Norway (Storfjorden) was caused by VHSV of a genotype that has hitherto only been detected in wild marine species and has never earlierbeen associated with outbreak of VHS in farmed salmonids. The proposal suggests an approach to this objective by screening saltwater populations of wild fish species, including salmonids, for VHSV with subsequent genetic characterization of detected virus. Experimental pathogenicity studies performed on susceptible species and development of a risk-based surveillance system will contribute to the understanding of possible transmission of VHSV from wild to farmed fish and vice versa.
Goal:
The primary objective of the project is to gain knowledge on the prevalence of VHSV in wild and farmed fish species and possible transmission of virus between different fish populations. Secondary objectives: (1) Screening and genotyping of coastal wild fish populations for VHSV with emphasis on fish species shown to be susceptible for VHSV infection. Material will be stored for possible use in future screening also of other infectious agents; (2) Identification of possible genetic virulence markers for VHS; (3) Experimental studies of the pathogenicity of different VHSV strains for various fish species; (4) Establish a GIS-based database; (5) Develop a risk-based surveillance system for VHVS in wild and farmed fish populations.
