Creative Chinook sick

In 2011, the Cohen Commission convened special hearings on disease in salmon farms, forcing fish farm companies and the provincial and federal governments to make their disease data public. When Dr. Kristi Miller took the stand, she revealed that Tofino-based Creative Salmon had for seven years been dealing with an undiagnosed disease which was causing jaundice in their fish. They had asked her to investigate. Her study revealed that Creative’s Chinook salmon had Piscine reovirus (PRV).

Fast forward seven years, with farmed salmon disease making headlines on a regular basis. A 2018 study from the Strategic Salmon Health Initiative (SSHI) sheds new light on PRV. The study looked at samples from farmed Chinook and Atlantic salmon. Piscine reovirus (PRV) is a Norwegian virus. In Atlantic salmon it is known to cause Heart and Skeletal Muscular Inflammation. Turns out PRV behaves differently in Chinook salmon. When PRV gets in the red blood cells of Chinook, it causes them to burst. The toxic levels of hemoglobin then overwhelm the liver and kidneys, resulting in an anemic appearance.

Dead fish swimming
The study found a high prevalence of PRV among farmed fish, with 65 to 75 per cent of both Atlantic and Chinook salmon carrying the virus and a quarter of them having a “high viral PRV load.” Fish living in pens have the luxury of being fed (and protected from predators) while they are sick. It’s hard to find PRV-infected fish in the wild, because they don’t survive. Given the high prevalence of PRV on BC salmon farms, study co-author Dr. Kristi Miller is very concerned about the potential for disease spreading to wild fish, stating “They are dead fish swimming as soon as they are physically compromised”.

The study is even more alarming because Chinook populations are collapsing on the west coast of Vancouver Island. Chinook are the preferred food of endangered southern resident orcas.

Contaminated bloodwater still flowing into Tofino Harbour
Remember Tavish Campbell’s shocking 2017 footage of bloodwater billowing out underneath fish plants? Some of that footage was taken at Creative Salmon’s processing plant in Tofino. Their bloodwater was tested and found to have PRV. Clayoquot Action was able to sample some of the rockfish feeding at the outlet pipe, and they had PRV too.

The pipe at Creative’s plant continues to spew disease-tainted bloodwater into Tofino Harbour. The Ministry of Environment promised a study, but has done nothing to turn off the tap.

Only removing salmon farms from wild salmon migratory routes will put an end to the spread of disease from farmed to wild salmon. It is inevitable that this will happen, but will it happen in time to save one of the most precious resources on the planet?

Dan Lewis is Executive Director of Clayoquot Action.

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 farm occupation

Fish farms occupied!

(Clayoquot Action is based in Tofino. We occasionally travel to other regions when relevant to our campaigns to protect Clayoquot Sound from mining, oil spills and salmon farms. For example, Imperial Metals’ 2014 Mount Polley disaster, and ongoing protests against Kinder Morgan’s pipeline expansion. We recently travelled to northern Vancouver Island to support First Nations occupying fish farms there. Clayoquot Action recognises and supports the indigenous rights and title of the Kwakwaka’wakw First Nations).

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

Mass die-off at Clayoquot farms

The call came in at the end of a busy day last week: ‘Cermaq is experiencing a mass die-off at two of their farms in Clayoquot Sound’. By early morning the next day we had assembled a volunteer boat driver and photographer, sourced a donated water taxi, and raised the funds to fuel the boat and hire a videographer complete with drone. We set off in anticipation.

The first farm we got to didn’t seem to have any unusual activity, other than the whole Herbert Inlet was a weird murky turquoise. An employee boated over to photograph us, and a polite exchange followed. ‘We’re not sure what this colour is’, he said. ‘We’ve been seeing it for six weeks—could be Chryso’ (shorthand for Chrysochromulina, a species of algae).

The second farm we reached was the Millar Channel farm, just kilometres north of the site evicted by Ahousaht First Nations, after it was occupied by the Yaakswiis Warriors last September. There was a hum of activity: workers tossing dead salmon into totes, which were lifted and dumped into semi-trailers designed to haul away animal remains. The tubes sucking the dead fish (morts) from the pens were getting plugged up with the sheer numbers, and divers were in the pens unplugging them. Continue reading
