Turning a blind eye The anti-farming lobby seem reluctant to engage with evidence that does not suit their narrative
A
S I write this commentary, Fisheries Management Scotland (FMS) have just posted a news story from the Guardian newspaper about restoring Finland’s river ecosystems, although it doesn’t mention salmon. Earlier in January, FMS posted the news that the River Tay fishing season was to be opened by actors Robson Green and Jim Murray, and at the end of December they posted the story from New Scientist about the Norwegian research on introgression from farmed salmon. Despite their interest in farmed salmon – their response to the Wild Salmon Strategy included calls for a reformed regulatory system that protects wild fish from the impacts of fish farming – they did not post news from any of the press coverage of my new paper (see “Fall in wild salmon numbers ‘not down to fish farms’”, Fish Farmer, January 2022). This was no surprise. FMS, as well as the wild fish sector, are only interested in stories about salmon farming that support their inherent belief that salmon farming is damaging to wild salmon. They are certainly not interested in news stories that might undermine their long-held narrative about the negative impacts of salmon farming. They hope that if they ignore any such stories that they will simply disappear, and they can continue their campaign against the salmon farming industry. Certainly, the Atlantic Salmon Trust, which is currently running the west coast tracking project with Marine Scotland Science (MSS), have remained silent, as have Marine Scotland Science themselves. I will be
now pushing MSS to amend its “Summary of Sea Lice Science” accordingly, in line with the latest findings. These will also be important evidence in the current

Scottish Environment Protection Agency consultation on sea lice management. Whilst most of the wild fish sector seem to want to ignore my new paper, when asked by the local press, Andrew GrahamStewart of Salmon & Trout Conservation was keen to voice his opinion. Rather than address the paper’s findings, Mr GrahamStewart told the West Highland Free Press that I am essentially a spokesman and an apologist for the salmon farming industry. Both these are news to me for I have never been asked by anyone in the industry to speak for them and I certainly would argue that the salmon farming industry has nothing to apologise for. Mr Graham-Stewart adds that there are numerous studies showing wild stocks are severely impacted by salmon farming particularly due to sea lice. These studies have been written by experts and have real credibility, implying that I am neither an expert nor have any credibility. Of course, Mr Graham-Stewart has never been willing to tell me this in person. Actually, Mr Graham-Stewart is incorrect, for whilst there are plenty of studies based on mathematical modelling and predicted mortality, there is a dearth of studies that show the actual impact of salmon farming. Just two are quoted in MSS’s summary of the science dating back to 2008 and 2009 and the evidence from these is extremely weak. Sadly, Mr Graham-Stewart is unwilling to discuss these papers. Both these papers used rod-catch data to illustrate their claims. None of the industry critics have ever argued that the data, collected from river proprietors by the Scottish Government, is unreliable and thus the
