Research finds farmed salmon virus may cause jaundice/anemia.

A virus known to affect farmed Atlantic salmon may cause jaundice and anemia in Chinook salmon, according to research released today by the Strategic Salmon Health Initiative (SSHI).

The revelation is reported in a peer-reviewed paper co-authored by Kristi Miller, a DFO scientist, and other researchers that will be published next month by the Canadian scientific journal FACETS.

“These findings add to the existing concerns about the potential impacts of open net salmon farming on wild Pacific salmon off the coast of B.C.,” says Brian Riddell, CEO of the Pacific Salmon Foundation, which is one of three partner organizations in SSHI, along with Genome BC and Fisheries and Oceans Canada (DFO).

The same strain of piscine orthoreovirus (PRV-1) that is known to cause Heart and Skeletal Muscular Inflammation (HSMI) in farmed Atlantic salmon — discovered in B.C. salmon farms by the same SSHI research team in 2016 — is now being associated with a disease called jaundice/anemia in Chinook salmon.
