The salmon was raised in a farm which was infected by anemia. However, researchers now believe the disease has spread to the wild in the Pacific Northwest.
The farms hit by the virus have lost more than 70 percent of their fish in last few decades. However, earlier the virus was never found in the West Coast of North America.
Researchers of Simon Fraser University said that the disease was found in 2 of 48 juvenile fish observed as part of a study of sockeye salmon in Rivers Inlet, on the central coast of British Columbia. The research was conducted after scientists observed a decreasing trend in the number of young sockeye.
According to environmental scientist Richard Routledge, the virus had stretched from the province’s aquaculture industry, which has traded in millions of Atlantic salmon eggs over the last two and a half decades, mainly from Iceland and Scandinavia. He agreed that no direct indication of that link existed, but noted that the two fish had tested positive for the European strain of infectious salmon anemia.
