Salmon virus originally from the Atlantic, spread to B.C. wild salmon from farms: Study

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 Science Advances.
