Frequently Asked Questions
"Is Piscine Reovirus (PRV) putting wild BC salmon at risk?"
Piscine reovirus (PRV) is a virus that can infect Atlantic and Pacific salmon. A recent study by the BC Centre for Aquatic Health Sciences (BCCAHS) concluded that PRV may have been in BC before fish farms, and it is a common virus that appears to be benign in BC.

"An independent review of all the science on PRV – a review requested by the B.C. government – finds no evidence that PRV causes disease in fish in the Pacific the way it appears to in Norway."Nelson Bennett, Business in Vancouver
PRV not a salmon killer in B.C.: study
"The situations in BC and Norway differ in terms of outcomes of a PRV infection. Furthermore, a PRV-positive test is a poor indicator of the long term mortality in BC’s farm ed salmon. By all accounts, PRV in BC acts in a benign fashion."Ahmed Siah, James Powell, Anthony Farrell, BC CAHS & University of British Columbia

"Genomic sequencing of PRV from BC has revealed some genetic differences when compared to PRV from other regions (Kibenge et al. 2013)... recent testing of archived samples held by DFO has revealed that PRV has been present in salmonids on the Pacific coast of North America for a much longer [than previously believed]..."Department of Fisheries and Oceans Canada
