A massive outbreak of salmon lice in the Clayoquot Sound UNESCO Biosphere Reserve is threatening to wipe out this year’s salmon runs. Cermaq’s documentation on salmon lice for April show that the numbers of salmon lice on seven of their fourteen Clayoquot farm sites are up to ten times higher than the threshold which requires treatment. The regulatory threshold is three motile salmon lice per farm fish.
There are 20 open net-pen salmon farms in Clayoquot Sound, all located on wild salmon migration routes. The salmon lice outbreak is occurring as wild salmon smolts are leaving Clayoquot’s rivers to begin their life at sea. Continue reading →
Wilderness photographer Tavish Campbell grew up on a remote BC island and has spent most of his life exploring the coastline of British Columbia above and below water. He recently dove under the Browns Bay plant near Campbell River—which processes Cermaq’s farmed salmon—and was disgusted to see a plume of blood water shooting out into wild salmon habitat. The effluent contained fish tissues, which were sent to the Atlantic Veterinary College for analysis. The samples tested positive for Piscine reovirus (PRV).
Creative Salmon in Tofino
Campbell then drove to Tofino to see what was happening with the effluent from the plant processing Creative Salmon’s farmed Chinook salmon. Continue reading →
A small ad appeared in Tofino’s newspaper about a week ago. It stated that Norwegian-based salmon farming giant Cermaq was applying to the BC Ministry of Environment for a permit to use Interox® Paramove® 50 to combat sea lice. A bit of searching on Cermaq’s website revealed their application is to deposit 2.3 million litres of pesticide—enough to fill an Olympic-sized swimming pool—into the pristine waters of the Clayoquot Sound UNESCO Biosphere Reserve over a three-year period.

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! Continue reading →
