Rural Affairs and Islands Committee

Salmon Farming in Scotland

Meeting date: 5 June 2024

Rachael Hamilton

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?

Could you repeat that, please? I did not hear what you said.

Okay. My last question on this particular issue is for Sean Black. Do you have regular meetings with the Scottish Government about severe welfare issues and mortality?

Okay. Thank you.

I will develop this line of questioning, convener. Rachel Mulrenan might get an opportunity to answer.

As we know, salmon farms are legally required to report weekly sea lice counts, but Sean Black said that the reporting is messy. Can you categorically say whether the reporting of sea lice and mortality has improved in recent years?

Maybe Sean Black could answer that.
