Study: Salmon virus originally from the Atlantic, spread to B.C. wild salmon from farms
Wednesday PM (SitNews) - Piscine orthoreovirus (PRV) – which is associated with kidney and liver damage in Chinook salmon – is continually being transmitted between open-net salmon farms and wild juvenile Chinook salmon in British Columbia waters, according to a new genomics analysis published today in
The collaborative study from the University of British Columbia (UBC) and the Strategic Salmon Health Initiative (SSHI) a partnership between Fisheries and Oceans Canada (DFO), Genome BC and the Pacific Salmon Foundation traces the origins of PRV to Atlantic salmon farms in Norway and finds that the virus is now almost ubiquitous in salmon farms in B.C.
