Last month a virus broke out in several open water salmon farms in British Columbia that has the region’s fish farm owners scrambling to mitigate their losses. Called infectious hematopoietic necrosis (IHN), the rabies-like virus was found among salmon in floating net pens belonging to Mainstream Canada, the biggest producer in the region. As a result, B.C. farms culled over 500,000 fish infected with IHN, which spreads rapidly and can kill up to 100 percent of a fish farm’s population. And it’s just the latest disease scandal to hit the province’s salmon farming industry.
