Evidence shows a debilitating virus found in British Columbia salmon was transferred from Atlantic fish farms, which then spread from Pacific aquaculture operations into wild fish, says a study published Wednesday.
The transmission of a virus tied to kidney and liver damage in endangered Chinook salmon is being fuelled by the exchange of the disease between open-net pen fish farms and wild stocks in B.C., a new study indicates.
Researchers used genomic analysis to trace the source of piscine orthoreovirus (PRV) to Atlantic salmon farms in Norway and then determined that the disease is also ubiquitous in salmon farms on the West Coast.
The genome sequencing of viruses from farms and wild fish demonstrates the disease is passed between farms and wild salmon.

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.

A virus is being transmitted between net-pen salmon farms and wild juvenile Chinook salmon in British Columbia waters, according to new findings published Wednesday in Science Advances.
The study traces the origins of piscine orthoreovirus, or PRV, to Atlantic salmon farms in Norway, and found that the virus is now almost ubiquitous in salmon farms in B.C. The virus has been shown to sicken fish.
The collaborative, peer-reviewed study was done by the University of British Columbia and the Strategic Salmon Health Initiative a partnership between Fisheries and Oceans Canada, Genome BC and the Pacific Salmon Foundation.
