Rural Affairs and Islands Committee

Salmon Farming in Scotland

Meeting date: 5 June 2024

Rachael Hamilton

Emma Harper quoted that some of the welfare and mortality figures are similar to those in Scotland, but the figures that I have seen comparing Scotland with Norway show that that is not the case.

SEPA has tried to make its life a little easier, because it does not have the capacity to gather that data.

My colleague Edward Mountain now has my cogs working on the gill health and sea lice interaction. The Government has brought in the new regulatory obligation for fish farms to meet on the threshold for sea lice. The ways in which we are controlling sea lice are clearly impacting on fish health—specifically, gill health. We have brought in something and created a new problem. Does the committee need to look at whether sea lice control is being done in the correct way? It could be, as Professor Martin said, the reason why mortality levels have increased so dramatically.

To be clear, it does not have to be gathered under statute and reported to the Scottish Government.

Does the salmon farming industry work with the universities and pay them to do that type of work? What kind of producer wants to have welfare issues and such mortality rates? The situation is affecting profits, and I presume that it also affects worker welfare and coastal communities, because why would anyone want to see discarded fish or lorries leaving fish farms with dead fish? Does the industry work with universities to try to establish—

To develop that, I asked whether there is scientific consensus on why mortality rates are increasing. Professor Martin talked about the situation with micro jellyfish and, obviously, the waters are warming, but nobody has mentioned the increase in the number of salmon being produced and whether that is having an impact, or the use of technology. Perhaps the risk is greater using the technology, even though some people have said that it is helping. You are the scientists. Where is the scientific consensus about tackling mortality rates?

Why can we not get those research licence sites?

Okay, so if this committee asked RSPCA Assurance to come in and given evidence, it would be able to disclose that information.

My question is for Professor Martin. If an animal that is destined for the food chain experiences stress, consuming its meat not a pleasurable experience. In this industry, at what point is a fish discarded if it has experienced poor health? You are saying that you have not noticed severe welfare issues to do with sea lice, but we know that there must be a threshold. What happens if, for example, a fish has been through all these processes and perhaps does not eat? Does it still go into the food chain?

SEPA figures indicate that, in Scotland, 17 million farmed salmon died last year. That indicates that mortality rates on fish farms remain high. Is there a scientific consensus on the key causes of that? If so, how is that data recorded? Is it aggregated and published?
