Cermaq is still having problems with sea lice on their Clayoquot Sound salmon farms. Just last week (mid-September), lice numbers at their Dixon Bay open-net pen operation hit 10.3 lice per fish—more than three times over the threshold for treatment. Despite trying a variety of new treatment methods, Cermaq is failing to control sea lice.
In 2018 the Clayoquot Sound UNESCO Biosphere Region saw salmon lice reach levels never seen before on the BC coast.
The source of these pests was the open-net pen salmon farms which clutter local wild salmon migration routes. Because salmon farms rear fish in crowded conditions, they act like lice incubators. The lice are then free to pass through the open nets to infest baby wild salmon, which would not normally encounter lice before they are old enough to have fully developed scales for protection.
A lice count of three or more per fish is the threshold for treatment on salmon farms. At one point, one of Norwegian-owned Cermaq’s Clayoquot farm sites reported lice levels of 54.7 per fish! With half a million fish per farm, that’s an explosion of 27 million lice—right when 2018’s tiny salmon smolts were migrating out of the rivers to their near-shore nurseries. Read More
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. Read More
Last fall Norwegian-owned salmon farming giant Cermaq applied for a permit to deposit over 2 million litres of pesticides in Clayoquot Sound. Clayoquot Action teamed up with SumOfUs to launch a petition opposing Cermaq’s application. Over 34,000 people signed that petition. The Tofino Chamber of Commerce and other stakeholders wrote letters opposing the application. The story hit the media—and the pressure was on!
Cermaq’s application not approved; province-wide sea lice review launched
The good news is that as a result of all this effort, Cermaq’s pesticide application has not been approved. Thanks to everyone who signed the petition and wrote letters—it worked! Not only that, but the province will be looking at all sea lice treatments on BC fish farms… Read More
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.

On the final day in Oslo, the Wild Salmon Delegation met with Cermaq, the Norwegian company with 15 salmon farm sites in Clayoquot Sound UNESCO Biosphere Reserve. We visited Cermaq to share with them the reasons why the Delegation had come to Norway; and to discuss our perspective on the similarities and differences between British Columbia and Norway, the emerging consensus that open-net salmon farming is a dinosaur technology, and the tide change unfolding daily in major Norwegian media.
