BC Salmon Farm Forced to Cull 560,000 fish

Atlantic salmon farms around Vancouver Island have begun testing and formed a special outbreak management team after an IHN virus outbreak at one farm led to a site quarantine and the cull of more than half a million fish.

IHN usually kills a fish within a week of exposure and can kill up to 100 percent of an infected population.
