The lying games by BC’s anti-salmon farming activists
Politicians, media, and the public being pummelled by falsehoods about BC’s salmon farmers.
By Fabian Dawson
If fearmongering was an Olympic sport, BC’s anti-salmon farming activists would rule the podium as they have mastered the art of spreading falsehoods.
Powered by questionable science, they have found allies among politicians, businessmen looking for government handouts, and a brainwashed horde howling to demonize what is one of the world’s most sustainable protein producing industries.
Recently they have ratcheted up their protests with juvenile antics at MPs’ offices while presenting a false picture of BC’s salmon farming industry at a parliamentary hearing.
The MPs at the hearing have been invited to come see for themselves the marine operations in BC but have so far declined afraid they will lose the votes from the activist’s following, which are mainly based in Liberal-held urban areas.
According to Fleetwood-Port Kells Liberal MP, Ken Hardie, the current hearing “concerns the way the Department of Fisheries and Oceans (DFO) conducts research and how it uses research findings to brief the Minister in her decision-making process.”
“Per your questions, no, I have not yet visited an aquaculture operation but, just this week, I received an invitation to do so along with the rest of the Standing Committee,” Hardie told SeaWestNews.
“That said, it is the mechanics of scientific activities at the DFO that are being studied, so a visit to an aquaculture operation, while useful in all respects, would not inform our report or recommendations in this study.”
The activists and their scientists have been claiming without a shred of evidence that DFO has been covering up studies that show open-net salmon farms pose a threat to wild stocks.
The MPs in turn have been giving them a friendly ear without challenging any of their conspiracy theories nor their discredited science.
The media has been reporting on the claims, without holding the activists to truth or questioning their lack of qualifications to speak on the issue.
All of this is happening as the Federal Government is set to make a decision on 79 salmon farming licences which are set to expire June 30.
“In recent weeks, a coordinated activist-driven campaign spreading these misinformed claims has created confusion and fear in coastal Indigenous and non-Indigenous communities,” said the BC Salmon Farmers Association (BCSFA).
“Those claims are false,” said the association.
Here is a summary and fact check of what the activists are pummeling our MPs, the media, and the public with.
IS PRV a threat to wild salmon? Answer: NO
Wild and farmed salmon are exposed to PRV after entering saltwater and wild salmon may also be exposed by their parents after spawning. Farmed salmon are tested and PRV-free when transferred from freshwater hatcheries into ocean farms. Viruses are the most common biological entity in the oceans, a teaspoon of seawater typically contains about 50 million viruses. Most viruses are harmless and infect bacteria and control bacterial abundance, influence marine communities and force biogeochemical cycles. Pathogens of marine animals, however, constitute a very small fraction of marine viruses.
There are multiple forms of the Piscine orthoreovirus globally. The form of PRV found in BC, PRV-1(a), does not cause transitory heart and muscle inflammation (HSMI) in Atlantic salmon or jaundice syndrome in Chinook and is not considered of any clinical significance by fish health professionals. In BC, smolts are screened for the presence of PRV before leaving hatcheries. PRV is not related to any human health concerns.
In the last ten years, many scientific studies have confirmed this lack of clinical significance from PRV.
In 2016, lab researchers found they could not produce jaundice after injecting PRV from jaundiced Chinook salmon into Chinook, Atlantic, and sockeye salmon.
In 2015 and 2019, Canadian Science Advisory Secretariat (CSAS) assessments concluded that PRV, attributable to Atlantic Salmon farms in the Discovery Islands area, poses no more than minimal risk to Fraser River Sockeye Salmon abundance and diversity.
A US-based study in 2020 Injected PRV extracted from Atlantic Salmon into juvenile Chinook, coho, and rainbow trout and failed to produce any notable disease or mortality.
Other work in 2020 reviewed global distribution of PRV in farmed and wild fish and found there are multiple genotypes of PRV. The paper includes a summary of a decade of studies on the virus:
A 2021 study found the virus poses a “very low risk” to BC’s population of wild Pacific salmon. The salmon remained physically fit with no change in respiratory fitness even when infected.
Was PRV introduced to BC from farmed salmon? Answer: NO
A 2015-study, that included archival samples from 1977, found PRV existed in BC well before salmon farming and is believed to be an endemic (normally found) virus.
A 2018 survey of wild salmon in Alaska and Washington state (locations where there are no salmon farms) found that PRV was widespread in wild populations.
Did DFO repeatedly suppress, ignore, and misrepresent scientific evidence of harm to its own decision-makers? Answer: NO
In 2011, Tofino-based farmed-Chinook producer Creative Salmon initiated a proactive study of jaundice (a yellowing of the abdominal and/or periorbital regions) in a very small number of farmed Chinook salmon. Researchers included Dr. Kristi Miller, DFO who studies the molecular identification of viruses, Dr. Gary Marty, BC Animal Health Center (Veterinarian/Certified Pathologist), and Dr. Sonja Saksida, Private (Veterinarian/ MSc in Veterinary Epidemiology.
PRV was identified from samples of jaundiced fish and control fish that did not exhibit jaundice. But there was no definitive link to causation between PRV and jaundice. All fish that exhibited jaundice were PRV-positive. Although the study showed there was a significant association with PRV and jaundice – causation could not be proven.
At the end of the study, the main report authors could not agree on the interpretation of the data and conclusions proposed by Dr. Miller, who is neither a trained virologist nor epidemiologist. This disagreement among the authors is an important point. According to widely accepted ethical standards for publishing scientific research papers, all authors must agree to the contents of the paper and be accountable for all aspects of the work. All salmon farmers support the dissemination of sound science released in the context of a peer reviewed published paper.
The detection of the presence of a virus does not mean there is disease as pointed out in a study review released in April 2022, new advanced molecular techniques are more sensitive in detecting the presence of infectious agents than traditional methods, but the biological significance of these new detections are difficult to interpret. This important review notes that “Fish health specialists from several of these agencies and organizations advise that any policy changes should be made only after further investigations to avoid wasting resources to conduct surveillance for organisms that are not significant to fish health or for non-infectious genetic material that does not represent a viable [disease causing] agent.”
Non-publication of this one study is far from being a conspiracy or a news item. The information has long been public.
In 2011, Dr. Miller discussed her findings publicly during the Cohen Commission. As part of the 2016-court case, Namgis vs. Minister of Fisheries, a summary of the study by Miller was submitted by the lawyers representing the Namgis (now public documents). Without permission, Dr. Miller used data from the study in another paper on PRV that she published in June 2017.
Copies of the draft project report and manuscript appear to have been leaked to the Pacific Salmon Foundation in 2017 and that same year Dr. Miller accused one of the coauthors of conflict of interest. This led to an investigation into the BC Provincial diagnostics laboratory (AHC). This investigation cleared the coauthor and his laboratory and found that there was “no evidence of financial or technical conflict regarding the diagnostic activities of the AHC” and that the “AHC operates at the highest levels of quality”.
The Globe and Mail wrote about this study in a 2020-article That article led to further articles about the lack of agreement by coauthors on the original study
Dr. Miller has repeatedly stated she believes PRV is a threat to wild Pacific salmon, notably Chinook and Coho, and that there is a transmission risk between farmed and wild salmon. However, additional research produced and reviewed by other DFO and non-DFO scientists does not support this claim.
In today’s world where food security is paramount, these activists with their cancel culture continue to make outrageous claims and allegations against DFO, distinguished scientists and fish health professionals, within and outside Canada.
They attack assessments by the Canadian Science Advisory Secretariat (CSAS) that have concluded that salmon farming poses no more than minimal risk to Fraser River Sockeye Salmon abundance and diversity.
“Baseless and outrageous claims only drive division in communities, create confusion and distrust, and do not contribute to developing better outcomes for coastal BC,” said the BCSFA.
