Cardiorespiratory fitness of farmed salmon unaffected by PRV

(03/14/19)

The respiratory systems of Atlantic salmon function normally even when carrying large loads of piscine orthoreovirus (PRV), new research by the University of British Columbia (UBC) has found.

“We didn’t find significant harm to the fish’s respiratory physiology despite the virus replicating to a load equal to, if not higher, than those seen naturally in wild or farmed fish,” said Yangfan Zhang, a PhD student in UBC’s faculty of land and food systems and lead author of the study published this week in Frontiers in Physiology and available here.

PRV is present in nearly all farmed Atlantic salmon on Canada’s west coast, and various strains of PRV have been detected in many salmonid species around the world. Consequently, the results are a positive step in reducing the uncertainty about the.....................................................
