Rural Affairs and Islands Committee

Salmon Farming

Meeting date: 10 May 2023

Finlay Carson

Our next item of business is an evidence session on salmon farming in Scotland. I welcome to the meeting Mairi Gougeon, Cabinet Secretary for Rural Affairs, Land Reform and Islands; Jill Barber, head of aquaculture development at the Scottish Government; and Malcolm Pentland, deputy director and lead for marine economy and communities at the Scottish Government. I also welcome Edward Mountain MSP, who is attending for this agenda item.

Thank you very much, cabinet secretary. It was 2018 when the Environment, Climate Change and Land Reform Committee and the Rural Economy and Connectivity Committee undertook the investigation into the impacts of aquaculture. I remember clearly it being said—it might even have been me who said it—that

“The status quo is not an option.”

We are quite some time down the road from then. A range of the questions today will probably be about whether we still have the status quo of five years ago and whether anything has changed. My specific question is this: what efforts have been made to address the issues around waste from farmed fish on the environment, particularly on the sea bed? Where have there been changes? What improvements have been made on sea bed waste? What are the challenges ahead as we look to increase the output from aquaculture?

Thank you.

The Rural Economy and Connectivity Committee and the Environment, Climate Change and Land Reform Committee both felt that there should be greater use of the precautionary principle. The first stated:

“The Scottish Government should provide strong and clear leadership in ensuring that the precautionary principle is applied, producing appropriate policy and guidance documents as necessary.”

Furthermore, the ECCLR Committee considered an independent assessment of the environmental sustainability of the predicted growth of the sector to be necessary.

There was a move to take fish of a heavier weight or that are older onshore. We talked about moving them offshore so that the time in which the fish are in cages in the sea is reduced. The impact of that might be to reduce the use of chemicals, to reduce mortality, or whatever. However, given the statements that I have just given, what work is being done to look at the additional impact of sea lice? Sea lice do not need to be controlled to such levels with older fish. What impact might that weight of sea lice load have on wild salmon populations? Is that something that you are looking at?

Thank you, Edward.

We have until approximately 11:30 for questions and discussion. I invite the cabinet secretary to make an opening statement.

I will make a couple of points before I bring Christine Grahame back in. We are talking about upwards of 25 million fish a year that die. Is the figure of 25 per cent accurate, or is mortality underreported, given that it is not a statutory requirement to report mortalities? How does that compare with other aquaculture industries around the globe? Is 25 per cent an accepted level? Finally, what mortality level do you find acceptable? I know that you want it to be as low as possible but, given that the Government has been looking at the issue for five years, what level of mortality do you find acceptable? We understand that there will be mortality, but what level is acceptable to the Scottish Government?

That concludes our evidence taking, and I thank the cabinet secretary and the officials for attending what has been a good session.

As that concludes our meeting in public, we will now move into private session.

Generally, though, if we are to accept that 25 per cent is fairly accurate, and although we want it to be as low as possible, you must have a figure in your head for what is acceptable. We all more or less agree that a 25 per cent mortality rate is unacceptable, because it means that 25 million fish effectively leave the food chain. Give or take a few per cent, what level would be acceptable? There has to be a target. Is it 10 per cent? Is it 20 per cent? We have been looking at this for years and years. What is a rough idea of what the mortality rate should be?
