I knew back in the 1980s when Norwegian salmon farming companies began to move to Canada that it would not be good for the BC coast. This concern was confirmed when Patrick Moore, Greenpeace cofounder turned anti-environmentalist, showed up at a public meeting in Vancouver to defend the fledgling industry. Back then I was (rightly) concerned that they would be located in the remote bays and inlets I loved to explore by kayak. It was many years before we began to fully understand the ecological impacts.
Disease transfer from farmed to wild salmon is dangerously easy
One of the big fears is the transfer of diseases from farmed to wild salmon. When you understand the mechanism of transfer, the implications are chilling. It came out during Canada’s 2010 Cohen Commission that an infected farm can shed up to 65 billion viral particles per hour. BC’s big tides cause strong currents, which can spread these viral particles far and wide. Remember, fish breath through gills, so the water they swim through comes in direct contact with their blood and voila—those viral particles are in the wild fish!
Clayoquot Action hosted filmmaker Twyla Roscovich and wild salmon researcher and advocate Alexandra Morton in Tofino in April. The pair toured BC this spring with Roscovich’s new film Salmon Confidential. They spoke to a sold-out house at the Clayoquot Community Theatre in Tofino after being welcomed to the territory by members of Tla-o-qui-aht First Nations.
In the film Alexandra Morton calls for citizens to stand up for wild salmon by forming Departments of Wild Salmon in local regions. Clayoquot Action is responding to this challenge by launching our Wild Salmon Virus Sampling Project.
Salmon feedlots, like any factory farm, are breeding grounds for disease. When a salmon feedlot has an outbreak, billions of viral particles are shed every hour. These particles are carried far and wide by ocean currents. Because wild fish breath by passing water over their gills, it’s not difficult for viruses to enter their bloodstream and voila! the disease has transferred from farmed to wild salmon. The solution is simple: remove salmon farms from wild salmon migration routes. Act now to protect Clayoquot’s wild salmon!
Beginning in late summer and early fall, Clayoquot Action volunteers will hit the rivers to sample wild salmon for the presence of viruses introduced by salmon farms. Stay tuned for further details…
