Key Takeaways
- Scottish salmon farming is economically significant and globally competitive.
- Environmental and social challenges must be addressed to ensure sustainable fish farming.
- Sea lice remain a major unresolved problem affecting fish health and farm profitability.
- Consumers should support responsibly managed salmon farms to promote sustainability.
- Scottish salmon’s high quality is a key factor in its market success.
What the video covers
- Salmon is the UK’s biggest food export since 2014, with Scotland producing about 160,000 tons annually.
- Norway is the world’s largest salmon producer, with 1.1 million tons per year.
- Scottish farmed salmon is known for its high quality and lean meat, fetching a premium price.
- Scottish salmon is popular in Southeast Asia and the EU, especially for sushi and sashimi.
- The reputation of Scottish salmon benefits from association with the high-quality Scotch whisky industry.
- Environmental concerns include chemical pollution from antibiotics used in fish farming.
- Escapes of farmed salmon pose ecological risks by competing with wild salmon.
- Uneaten feed and high fish density reduce oxygen levels and harm local biodiversity.
- Social issues such as labor exploitation occur in some salmon farming regions, though not in Scotland.
- Sea lice infestations weaken fish, leading to premature harvesting and economic losses; current control methods are limited.

Speaker A
Now, there's one point I want to say straight away and that I want to talk about something called sea lice, which is a nasty kind of pest that infects salmon. And so if you don't know what to say, just say a nasty pest or something similar, and hopefully that will do.
Speaker A
And now I'll begin.
Speaker A
Ladies and gentlemen, what do you think the United Kingdom's biggest food export is?
Speaker A
Well, as you might have guessed, from the title of the subject, the answer is salmon.
Speaker A
In particular, salmon produced in Scotland since the year 2014, this has been Britain's biggest food export.
Speaker A
Before that time, it was sweets and chocolate.
Speaker A
But now salmon, which is perhaps a healthier option.
Speaker A
Scotland produces about 160,000 tons of salmon every year.
Speaker A
But I would just say that the world's biggest producer of salmon is Norway.
Speaker A
And they produce 1.1 million tons of salmon a year.
Speaker A
So Scotland's contribution is less than 10%.
Speaker A
Nevertheless, Scottish salmon is something special.
Speaker A
It is seen, it's perceived as a high quality product.
Speaker A
Obviously, this salmon is not wild salmon, it is farmed.
Speaker A
The fish are kept in cages in the water a bit like battery hens, I suppose.
Speaker A
But efforts are made to ensure that the fish, at least in the cages in Scotland, are not jammed in too tightly, so they have room to swim around.
Speaker A
As the fish can swim around, they develop more muscle fat and therefore more muscle.
Speaker A
I beg your pardon, and therefore less fat.
Speaker A
And this lean fish attracts a higher price on the market.
Speaker A
So Scotland can charge 10% above the average price for their salmon.
Speaker A
This very lean fish is extremely popular in Southeast Asia, and that includes China as well.
Speaker A
In 2016, which is the year I have figures for, 11,000 tons of salmon were exported to Southeast Asia, and that was worth £73 million Sterling.
Speaker A
And this low-fat fish is very popular in Japan, for instance, for the production of sushi and sashimi.
Speaker A
For instance, Scottish salmon is also very popular in the European Union.
Speaker A
In that same year, Scotland exported 35,000 tons to other EU countries.
Speaker A
Of course, as I said, Scottish salmon is of high quality.
Speaker A
And its good reputation is helped by a somewhat unusual ally, namely, the Scottish whisky industry.
Speaker A
Because it seems that these two might not work together very well.
Speaker A
Although personally, if I had a glass of whiskey and a bit of smoked salmon, it would be very pleasant.
Speaker A
Yet, because of the fact that the Scotch whisky industry is considered to be high quality, a lot of people conclude that, well, if the whiskey is good, the salmon must be good as well.
Speaker A
And that has helped the salmon industry to export its products so effectively.
Speaker A
Nevertheless, fish farming is not something that is universally welcomed by everybody.
Speaker A
Environmentalists have been particularly concerned about some of the issues surrounding the farming of salmon.
Speaker A
You might think that this might be just a form of scaremongering.
Speaker A
But it seems to be sufficiently important because the Worldwide Fund for Nature, the WWF, have listed fish farming as a priority issue, which they want to deal with.
Speaker A
They mention five issues, although I personally think some of them overlap somewhat.
Speaker A
Let me explain what those issues are.
Speaker A
Firstly, there's the question of chemicals.
Speaker A
These fish are fed antibiotics for two reasons, firstly, because it helps them to grow more quickly.
Speaker A
But secondly, because as these fish are so close together, there's a real risk that they might catch certain diseases.
Speaker A
And therefore the antibiotics are supposed to combat that.
Speaker A
But the cages are just in Rivers or in the sea, and the water flows in and out of them.
Speaker A
So the antibiotics get out of the cages and start to pollute the Rivers and seas around and have an effect on the marine life.
Speaker A
The second problem they raise is escapes.
Speaker A
Because some of these salmon actually get out of the cages and then compete with wild salmon for the same scarce feed resources.
Speaker A
Which of course, is a problem for the environment, because all of a sudden there are much more salmon in the river than there would normally be.
Speaker A
The third problem has to do with the way that these fish are fed.
Speaker A
They are fed a highly nutritious diet, and some of that food is not actually eaten by the fish.
Speaker A
But actually again gets out into the surrounding water.
Speaker A
At the same time, this high concentration of fish in a small place space reduces the level of oxygen in the water.
Speaker A
Both of these things have an effect on the biodiversity of the surrounding area and therefore can form a problem.
Speaker A
Now, the fourth issue that the WWF have mentioned is not a problem in Scotland, but it is in other areas.
Speaker A
And that is social issues.
Speaker A
You see, this industry is very labor intensive.
Speaker A
And in some countries the workers in the industry are being exploited.
Speaker A
So that again, is a problem that environmentalists and come to that human rights experts have raised.
Speaker A
And finally, there's the question of disease and pesticides.
Speaker A
Despite all the antibiotics that I mentioned earlier on, these these animals do get sick.
Speaker A
And one thing these fish seem to be particularly susceptible to is a pest called a sea louse or sea lice.
Speaker A
Now these pests, whatever they are, they get into the fish.
Speaker A
And as a result, the fish weakens.
Speaker A
And so the only thing that the fish farmers can do is to kill the fish straight away and sell them, even though they haven't reached their maximum weight.
Speaker A
Which means that the farmers lose out.
Speaker A
Unfortunately, there's no cure for these sea lice.
Speaker A
People have had various ideas, put them in bigger cages deeper in the water where the lice won't survive, for instance.
Speaker A
Or introduce other fish which would eat the sea lice.
Speaker A
Which works in theory.
Speaker A
But these fish prefer to eat the feed that's there for the salmon.
Speaker A
Plus, the salmon actually like to eat these fish.
Speaker A
So it doesn't work very well.
Speaker A
What we should do, therefore, is to continue enjoying our salmon.
Speaker A
I don't think we have to say we won't eat salmon anymore.
Speaker A
But let's be responsible and ensure that the fish that we eat come from farms which are properly managed.
Speaker A
Thank you.
