Clayoquot Salmon with lice

Clayoquot emergency drug trial

Norwegian salmon farming giant Cermaq has a salmon lice problem on their Clayoquot Sound salmon farms. Documents released through Access to Information indicate Cermaq obtained an Emergency Drug Release to use the insecticide Lufenuron to control salmon lice in the Clayoquot Sound UNESCO Biosphere Region.

Last year saw salmon lice numbers in Clayoquot spike to levels never before seen in British Columbia, up to 55 lice per farmed fish—eighteen times the threshold for treatment set out by Department of Fisheries (DFO). Independent monitoring found wild salmon juveniles had lice counts as high as 50 per fish.

Cermaq is unable to control their salmon lice epidemic in Clayoquot Sound. Their 2018 lice outbreak likely devastated last year’s wild salmon cohort, and their 2019 numbers are already up to 5 times the DFO limit, right at the beginning of the wild salmon out-migration window.

In 2018 Cermaq had their Aquaculture Stewardship Council (ASC) eco-cert suspended on 3 Clayoquot farms, and voluntarily culled the fish on their Plover Point farm as the lice infestation there was uncontrollable.

2018 Clayoquot lice numbers “shockingly ugly”
A DFO document obtained through ATIP refers to 2018 Clayoquot lice numbers as “shockingly ugly”. The ATIP document further states “Theoretically [Lufenuron] should prevent lice colonization up to the beginning of the outmigration window, but this will be our first field trial of it in BC”.

Lufenuron is not approved for use in Norway, Cermaq’s home country—the manufacturer failed to get approval. The application was withdrawn before it was rejected—the reasons for withdrawing the application are shrouded in secrecy.

Norwegian fish farm companies are losing about US $2 billion annually, due to the high cost of lice treatment, and the loss of up to 20% of their fish each year. If Lufenuron was the magic bullet to control sea lice, why would the Norwegian government not have approved it? Some very serious concerns must have been raised.

There are human health concerns with use of the drug, which resides in the fat of treated animals. The flesh of treated fish cannot be consumed by humans for 350 days after treatment. This raises questions around how Lufenuron-treated fish will be disposed of in the event of a mass die-off, and in the event of an escape, whether Lufenuron-treated fish might be eaten by a predator which could later be caught for human consumption.

Lufenuron kills crustaceans
Lufenuron acts as a chitin synthesis inhibitor; it kills crustaceans like fleas and lice by preventing them from growing a new exoskeleton after moulting. This raises questions about its impact on aquatic organisms in the marine environment—particularly crustaceans like crab, shrimp and prawns, as well as molluscs and cephalopods (octopus). Although the drug will be administered in freshwater hatcheries, it stays in the fish for a very long time. How much will be excreted by fish into the ocean? How long will Lufenuron persist once it settles beneath the fish farm? And how readily will it be accessible to sea creatures?

Cermaq’s solution to their lice problem for 2019 was supposed to be the Hydrolicer—a boat which removes lice from farmed salmon using a stream of pressurized seawater. But Cermaq’s is not yet in operation—although it was scheduled to arrive before the wild salmon outmigration window started on March 1st. Hydrolicers only work in combination with drugs; and come with their own challenges: the procedure is stressful for farmed fish, and can lead to die-offs and disease outbreaks, increasing the risk of disease transfer to wild salmon.

The most important thing here is to protect this year’s wild salmon smolts. That would require having lice numbers under control during the out-migration window from March to June. Clearly Cermaq has been unable to achieve this.

It’s time to demand that Fisheries Minister Jonathan Wilkinson take a stand for wild salmon. He needs to stop approving toxic chemicals for use on open-net pen salmon farms, and order a harvest of lice-infested farmed salmon immediately, before they can harm juvenile wild salmon currently migrating out from rivers into the ocean.

Clayoquot sea lice epidemic

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. Continue reading

Clayoquot salmon lice outbreak devastating

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

Clayoquot pesticide permit approved

Cermaq to move ahead with toxic sea lice treatment

The provincial government has granted Norwegian salmon farming giant Cermaq a permit to dump over 2 million litres of pesticide into the pristine waters of Clayoquot Sound. That’s enough to fill an Olympic-sized swimming pool. The pesticide use application sparked controversy last fall, when thirty four thousand people signed a SumOfUs petition opposing the permit.

Environment Minister George Heyman announced in December that his government will be reviewing all pesticide use on open-net pen salmon farms in BC. That review is not yet finalized. On their website Cermaq says it has ‘no immediate plans to use this treatment’—so what’s the big rush?

Fish farms under pressure

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… Continue reading

Tofino’s tainted fish farm blood

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).

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

Deny Cermaq’s pesticide permit

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.

Salmon harming harms wild salmon

Sick fish in the Sound

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

Big summer for wild salmon!

It was a big summer for wild salmon. Captain Paul Watson and the Sea Shepherd Conservation Society donated their vessel, the R/V Martin Sheen, to BC biologist Alexandra Morton. Operation Virus Hunter was launched! The goal was to track farm salmon viruses and audit salmon farms along the Fraser wild salmon migration route.

Things ramped up in August when the Musgamagw Dzawada’enuxw chiefs (pictured above at a Vancouver rally) issued an eviction notice to all salmon farms in their territory, including Cermaq, the same Norwegian company operating in Clayoquot Sound. The Nation has been opposing salmon farms in their territory for decades. This summer Band Councillor Melissa Willie instructed by Chief Willie Moon to climb aboard a salmon farm to request a sample of the farm fish for testing. Their request was denied. Continue reading

Alta reflections

The indigenous people of northern Europe are called Sami. They are known for herding reindeer on the tundra. What we learned while in Norway is that the coastal Sami culture centres on wild salmon, much like coastal Natives in what is now called British Columbia. These two species, with their predictable migration patterns, provided the protein on which a rich culture was founded—the Sami.

The Alta River in northern Norway is famous. The stretches downstream of Northern Europe’s biggest canyon teem with big salmon, and have been a mecca of sports fishing for many years. The reindeer herds also come to the banks of the headwaters to calve in the rich pastures.

A major dam on the Alta River?
Back in 1970, the Norwegian government announced plans to build a major hydroelectric dam on the Alta River. Questions about the reindeer, the wild salmon, or interference with Sami rights were not even considered. What became known as the Alta Controversy began as a conflict between the Sami and the Norwegian government. The Sami village of Masi was to be flooded, and people rightly feared extensive disruption of the environment. Eventually the resistance morphed into a People’s Movement which became a nationwide flashpoint for a growing awareness of the need to protect the environment and uphold indigenous rights.
