Rick Routledge, a Simon Fraser professor, uncovered piscine reovirus in 13 out of 15 cutthroat trout collected from Cultus Lake. While this is no cause for concern for humans and their consumption of fish, it could have an impact on other freshwater populations of fish such as salmon.
According to Routledge, the virus is widespread in Norwegian salmon farms where it has been linked the death of 20% of infected fish.
