The Aristocrats versus the Billionaires

A small but interesting illustration of just how far the mainstream media, typified by the Murdoch Press, has sunk can be found in the puff piece that appeared in the London Times on 5 May, over the byline of Ms Jenny Hjul. The full piece can be read below, along with the detailed response sent to the paper by John Aitchison of Friends of the Sound of Jura.
Those of us who have spent years, in some cases decades, trying to protect the environment and the wild fauna and flora of Scotland’s coasts are very used to being accused of self-interest. Ten or so years ago I was constantly the victim of anonymous trolls, one of whom described me as a “tweed clad aristocrat” (my genealogy as a Glaswegian descendent of those whose migration was not entirely voluntary can be supplied on request). Resort to ad hominen slurs is despicable, but also signals the lack of a proper argument. Not as irrelevant is the connection between Ms Hjul and the industry that she purports to be impartially commenting upon; she is the editor of Fish Farmer Magazine!
Ms Hjul may find it difficult to believe, but there are people around who truly care about things like dumping toxic waste on the seabed, allowing unnaturally large populations of sea lice to spread along the mouths of salmon rivers and importing non-native fish stocks, many of which escape each year and breed with local salmon.
Scientists internationally have established beyond any doubt that escaped caged salmon can and do interbreed with wild ones. It is for this reason that Norwegian regulators do not allow their industry to cultivate Scottish stock there. And yet, at a meeting I attended with Marine Scotland in 2018 in response to a direct question from me, one of their senior scientists, under the steely glare of his Civil Service minder, said that “there is no evidence of interbreeding in Scotland”.
Interbreeding is deadly for the survival of wild fish precisely because of the latter’s genetic programming to return to the spawning river. In this one regard Henry Williamson, author of Salar the Salmon, was right; don’t be distracted by his enthusiasm for human eugenics!
Of course all this is of concern to those who own rivers and want to preserve their main asset, the salmon in them. Of course it's they who have stumped up the cash to pay for what was no doubt very expensive research, which, in anticipation of industry whining, they had peer-reviewed. They have been very open about who they are, unlike Ms Hjul.
In his letter John Aitchsion refers to the 2018 parliamentary inquiry, which concluded that the status quo is not an option. Virtually nothing has happened since, while the target of doubling production by 2030, which we now know is government and not industry led, continues.
The decline of wild salmon in Scotland is now so well advanced that our sub-species may be close to extinction. Soon the only reminders of what we once had may be the photographs of salmon leaping in remote Highland waterfalls that the industry habitually uses in advertising.
Alastair McIntosh describes what is happening along our west coast as nothing other than a twentyfirst century land grab. Our seabed and the creatures that live on and above it are one of Scotland’s greatest assets, yet are being auctioned off to foreign owned companies taking advantage of the fact that Scotland’s regulators refuse to act in the face of overwhelming scientific evidence. It can thus be seen that rather than being a class warrier against the aristocracy Ms Hjul is in fact an apologist for, mainly Norwegian, billionaires. The ongoing official dishonesty is intolerable and obscures what is a straightforward choice between monoculture and diversity, between giving away or keeping control of our land. There should be an open, public debate about this, free from attempts to smear the issues with class.
Ms Hjul’s Article
“Scotland’s salmon farming industry has come under attack yet again from its regular detractors in the wild fish lobby. Normally, criticism from this quarter might be shrugged off by salmon farmers, who have long been the target of the angling community, which blames the decline in wild stocks on fish farms.
But both the grounds and the timing of the latest campaign leave a nasty taste. In a new report, the anti-salmon farm group Salmon and Trout Conservation Scotland and the Sustainable Inshore Fisheries Trust demand the government cuts support for the sector because its economic value and the number of people it employs have apparently been exaggerated.
This is quite a claim for a Scottish success story that is worth more than £1 billion a year to the economy, creates thousands of jobs and produces the UK’s biggest food export. The report’s authors base their logic on unchecked statistics (they even contradict their own figures) and the premise that the growth of salmon farming comes at the expense of others, including creel fishermen, recreational fishers and divers, and sea wildlife tourists.
Nowhere do they provide evidence that salmon farm sites — which if placed together would occupy the area of just two 18-hole golf courses on our vast coastline — cannot coexist happily with all other marine users. But it is not only the report’s unfounded assumptions that are so objectionable.
Fish farmers have toiled throughout the coronavirus crisis to maintain a steady supply of salmon to the supermarkets. Their role is vital, as is that of the fish processors, boat crews, hauliers and sales and distribution teams. Undermining all their efforts are wealthy river owners, motivated by their determination to protect their riparian inheritance and too blinkered to see how shameful their defence of privilege looks at a time like this. Their grievances have for years played on environmental concerns but with wild salmon depleted in east coast rivers as well as in England, where there are no farms, they have had to change tack.
A report that pits hard-working food producers against silver spoon sports fishermen is a massive own goal, one that will be remembered the next time the angling lairds take aim from their estates.
Mr Aitchison’s Response
“Jenny Hjul seems to have swallowed the salmon farming industry’s PR line, that only ‘silver spoon lairds’ care about the impact of their fish farms, or about the dodgy economic figures that they and politicians have used to support a doubling of production to 300-400,000 tonnes of farmed salmon by 2030. Doing so will also double their pollution, pesticides, parasites and diseases, which directly impact jobs in coastal communities that depend on the health of the sea. The harm caused by doing this has not be assessed.
All the pollution from Scotland’s 200 plus fish farms is dumped into the sea. People in our communities know that it spreads very far and is toxic to life on the seabed, including the crabs, lobsters and prawns our fishermen depend on. Fish farmers also shoot seals and illegally disturb porpoises and dolphins with deafeningly loud ‘seal scarers’, and their open-net cages release billions of parasitic sea lice, which are deadly to wild salmon and sea trout.
Many of the thousands of people we represent work as fishermen, scallop divers, wildlife guides and in accommodating visitors to our coast. Few are anglers and none are lairds. Every job here matters, and they are threatened just as much by COVID-19 as jobs in fish farming.
Deciding whether to allow this industry to expand should be based on the facts, including a full accounting of the costs, and not just the claimed benefits. This largely foreign-owned industry exports its profits and does not pay to clean up its pollution or the impact of its sea lice. Official statistics show that only about 1200 people work directly on Scotland’s fish farms. The Economic Contribution of Open Cage Salmon Aquaculture to Scotland report shows that inflated figures have been used to justify expansion, exaggerating new jobs by 251% and economic benefits by 124%.
Fishermen are now so concerned about the ‘significant effect on fishing and marine life due to sewage and chemical pollution’ affecting their livelihood that the Clyde Fishermen’s Association is calling for ‘an immediate moratorium on any new marine open cage fish farms and any expansion of existing fish farm sites’ in the Firth of Clyde, ‘as any expansion of the industry will be unsustainable and may result in irreversible damage caused to the environment’. The CFA has 200 members.
According to Fisheries Management Scotland, wild salmon and sea trout are now at crisis point, with populations at an all-time low. Sea lice from farms are not the only problem but they can have a huge impact:
Scottish Natural Heritage agrees: ’we believe there is now significant scientific evidence to conclude that population level impacts are possible’. Marine Scotland adds: ‘Salmon aquaculture can result in elevated numbers of sea lice in open water and hence is likely to increase the infestation potential on wild salmonids. This in turn could have an adverse effect on populations of wild salmonids in some circumstances.’
Its website quotes research that found a ‘reduction in the catches and counts of salmon on the west coast correlating with increased production of farmed salmon’, and ‘showed that rivers with farms had significantly lower abundances of juvenile salmon than those without farms’. It also quotes a study on the River Errif, in Ireland, that ‘estimated that returns of salmon after one year at sea were 50% lower, in years following high sea lice levels on nearby salmon farms during smolt migration.’ The authors considered that ‘the reduction in returning salmon numbers due to sea lice could affect the viability of the salmon population in the long term.’ Other Norwegian and Irish work also ‘indicated that salmon lice can influence the population status of wild salmon’.
Last week an expert group convened by the Scottish Government, including the Scottish Salmon Producers Organisation, published its recommendations to Ministers on the impact of fish faming on wild fish. After years of prevarication, the SSPO has finally acknowledged ‘the potential hazard that farmed salmonid aquaculture presents to wild salmonids’, and that the ‘finfish aquaculture regulatory regime should be reformed to ensure that it is fit for purpose …(and) … should protect wild migratory salmonids’. Perhaps the fish farmers didn’t tell Jenny Hjul.
In 2018 a Scottish Parliamentary Inquiry said that ‘urgent and meaningful action needs to be taken to address regulatory deficiencies as well as fish health and environmental issues before the industry can expand.’
Two years on the expansion is in full swing but little has been done to address the environmental issues.
Thoughtless caricatures like Hjul’s help no-one except this dirty industry, which is clinging to its old-fashioned methods because they are cheaper. Fish farming must be cleaned up before allowing it to double in size.”

What happens to the dead fish?


Our greatest failure to date was our campaign against an application to plant a huge industrial fish farm Port na Morachd, the lovely bay in the above image. Although there were over 800 objections the application was duly rubber-stamped by Argyll & Bute Council.

That process led to our greatest success to date, our complaint to the European Union, which led directly to a change in the law regarding the disposal of dead fish.

In the course of campaigning against the applications at Ardmaddy members of saveseilsound discovered that 82,663 mature salmon had perished at Ardmaddy over a few months, ending in December 2011. 

The total waste created thereby was reported by the operators as 256 tonnes.

Ardmaddy is an extremely remote site, with no road access. Residents were alarmed at the possibility that this enormous quantity of waste might simply have been dumped at sea. Even worse, what if the dead fish had been recycled into fish food for fish farms?

We decided to find out and were astonished to discover that nobody in officialdom knew!

Argyll & Bute Council didn’t even know that this disaster had happened. 


SEPA had learned some months after the event, when Lakeland Marine Farm sent in its mortality figures, but they hadn’t bothered to do anything. 

Nobody outside of Lakeland knew the cause of death.


We then found that this was all entirely within the law as it then stood, because the UK had negotiated a special derogation from the Animal By-Products Waste Directive exempting almost the entire aquaculture coast from environmental protection.
The Directive was brought in after the BSE “mad cow” scare and of course at that the fish farming industry was much smaller than it is today.
Strictly this belonged to the field of public health and safety and we took our complaint to the section of the EU Commission in Brussels with specific responsibility for this.
The Complaint was lodged in April 2012 and we didn’t hear much until we got a message on 24 June 2015 as follows:

“Extensive correspondence has taken place between the Commission services and the UK authorities in the context of the EU Pilot investigation which was triggered by your complaint. I can inform you that the UK authorities have in this context presented an action plan which includes an envisaged amendment to the Animal By-Products (Enforcement) (Scotland) Regulations 2013 and improvements to the official control activities, in particular in relation to contingency planning for large scale fish mortality disposal. In order to maintain the necessary trust-based cooperation between the Member State and the Commission during the pending EU Pilot investigation, further details of the action plan submitted by the UK authorities cannot be explained at this stage. However, the timeline provided by the UK authorities shows, inter alia, that the legislative amendment is envisaged to enter into force by the end of year 2015. The Commission services are closely following up with the commitments of the UK authorities in this context.”

Success dressed up as failure


In April 2016 we learned that the law had now been changed, as we were told that the Complaint had been shut down on the basis that it was no longer necessary!

We hadn’t spotted that in late 2015 the Scottish Government had held a “public consultation” on the Animal Waste Regulations. This was plainly our fault, but it might have been courteous for the government to have informed us and given us the opportunity to comment. Instead the invited consultees were virtually all from the industry.

Among the options given was for the law to be left unchanged and in continuing breach of the EU Directive, which would have involved the UK constantly breaking the law and being fined. It’s odd that this was even considered, but it seems that a cost benefit analysis showed that it could be more expensive to pay the fines than to dispose of the waste safely. 

And also a threat to health and safety maybe?


In the event the safe option was chosen and the new law came into effect in January 2016. As a result all waste has to be treated by a process called ensiling, basically the dead fish are put in a vat of formic acid which turns them into smelly slush that can be safely disposed of in landfill. Small amounts can be handled on site, while larger quantities are dealt with industrially.

Incredibly, there is still no supervision. As in all its operations the industry is self-policing and companies are trusted to behave.

We decided to find out who had taken part in the Consultation and what  they had said. We sent a Freedom of Information Request to the Scottish Government and have now received copies of the consultation responses.

The majority of responses were from either local authorities or land-based industries. SSPO agreed that the law should be changed, as did Dawnfresh, who operate in Loch Etive. One of the currently operating companies, who  insisted on their identity being withheld, sent the following gem:



So, this company were actually happy that the consequences of some catastrophic repeat of Ardmaddy in future would just be dumped on a local landfill site, whose workers and an  unwitting local population would be left with the consequences!

The Joys of Thermolicing

Scottish Sea Farms has purchased Scotland’s first Thermolicer machine

The weird and wonderful monstrous machine above is a Thermolicer, the incredible secret bullet that the fish farming industry has bought to deal with the menace from sea lice. Judging by recent reports there are some problems with it:



Here are some (Soon to be) 


Frequently asked Questions

The industry may have bought the machine, but who paid for it? 


Perhaps we did!

Here is part of a news release from last October:

The drive to reduce sea lice and increase harvests of Scottish salmon has received a £1.76m boost, following a successful application to the European Maritime Fisheries Fund (EMFF).

Coordinated by the Scottish Aquaculture Innovation Centre (SAIC) on behalf of 11 companies, the award will enable a range of alternative technologies and approaches to be trialled in Scottish waters so that they can be evaluated for their ability to reduce sea lice – a naturally occurring parasite that affects farmed fish, costing the global industry over $1bn each year.
Says SAIC CEO Heather Jones: “The technologies being explored are capital intensive and their outcomes in Scottish waters are as yet unknown, therefore the financial and operational risks to industry are significant. By reducing those risks, this EMFF award will help catalyse trials on a commercial scale as opposed to an ad hoc or local basis.”
It’s not just the companies involved in the supported projects that stand to benefit. As part of the EMFF award, SAIC will commission a research project to capture the lessons learned, and share best practice with the wider sector and supply chain. There is also the potential to develop next generation technology for sale at home and abroad.
Amongst the alternative solutions being trialled is hydrolicer technology which uses low pressure water jets to dislodge sea lice; an innovative ‘bundle’ of technologies that brings best practice approaches into a single system; and a Thermolicer device which capitalises on the parasite’s low tolerance to sudden changes in temperature by briefly bathing fish in warmer water.
Comments Jim Gallagher, Managing Director of Scottish Sea Farms and one of the partners involved in the Thermolicer trials: “Everyone is clear on the real and urgent need to reduce sea lice. However significant capital investment is required to trial new solutions. The EMFF award is contributing additional resources to those invested by industry, enabling Scottish trials on a commercial scale. The new equipment will be accessible by many companies in Scotland’s salmon sector, supporting the industry’s common purpose in accelerating the widespread adoption of effective sea lice controls.”

So, how does the Thermolicer work?


According to the manufacturers Steinsvik

"The Thermolicer is a machine for commercial scale dip or bath treatment of fish. A sudden rise in water temperature is a well-known method of killing lice. We have developed a machine that does this on a commercial scale.
The fish are crowded and pumped into the machine where it passes through the processing loop in 25–30 seconds. Treatment water holds 30–34 degrees depending on ambient sea temperature. The treatment water is filtered, aerated, oxygenated and reused in the system. This simple and environmentally friendly treatment has an effect that goes beyond the expected in traditional treatment agents like chemicals and medicines."

If it's so terribly good, why did it kill the fish?


You will see from the BBC report reference to the fish suffering from Amoebic Gill Disease. The Thermolicer is of course not a treatment for AGD, so it seems likely that the fish had the disease and were also infested with sea lice. This is fairly common, because AGD, a sort of fish breathing disease weakens its victims and makes them more likely to be compromised by sea lice. Correspondingly, sea lice infested fish are bound to be weaker and more susceptible to disease.

34 degrees is the temperature at which sealice die, but it seems to have been simply too hot for its patients.

What is the maximum temperature which a salmon can endure?


Like most “cold-blooded” animals, salmon have little ability to regulate their internal temperature, so their body temperature is usually very close to that of the surrounding environment.


Research a few years ago Steinhousen et al and Eliason et al showed that salmon acclimatised to European water temperatures of a maximum of about 12 degrees began to show cardiac issues at temperatures above 21 degrees. Ambient water temperature in Scotland is rarely much above 8 degrees, so one can only guess the impact of a sudden increase to four times that. It seems likely that even healthy fish would be at risk of being compromised.

Does anybody care about whether or not the salmon suffer, being heated to four times what they're used to?


Seemingly not!
