I think that it has been answered. It was about sea cage research sites elsewhere on the globe. What is the barrier to Scotland having those? Is it just cost?

I am thinking about what Ariane Burgess said about stress in salmon. I am assuming that using biological methods or cleaner fish might be less stressful for the salmon. In the previous panel, it was said that the cleaner fish—the wrasse—were all wild caught, but I understand that the lumpfish are farmed, and work is being done and millions of pounds are being invested to look at breeding and husbandry programmes for other specialised cleaner fish. How does that all that link with improved welfare and reduced stress for the salmon?

So, we do not need more regulation; we just need to make it work better and condense the structure.

Do you mean in terms of regulatory bodies, the marine directorate, SEPA, Government? Is that what makes it a wee bit disjointed?

Thank you.

We are running out of time—okay.

Max Warner, you have done modelling around investment in prevention to keep folk healthier. What modelling has been done to show that up-front investment will prevent cancer, reduce obesity and diagnose type 2 diabetes earlier, and have you done modelling that shows that preventing things now will save £X in terms of secondary care?

Thank you. The convener is giving me the eye, so I think that I should make that my final question.

You said that cervical cancer screening uptake has reduced, but I am aware that there is self-sampling research going on now, and there is also research about urine testing for the human papillomavirus. Would that help? It is less invasive than traditional screening, so can we chivvy along that research so that we can also use either self-sampling or urine testing to screen people?

I have a quick question for Max Warner, as I am conscious that he has not said a lot.

Good morning to you all. I am interested in the good work that is being done on establishing rapid cancer diagnostic services. They were launched in Dumfries and Galloway, Ayrshire and Arran, Lanarkshire and the Borders in 2021, since when the uptake for bowel cancer screening seems to have become the highest ever in Scotland.

On 30 April 2022, there was a 67 per cent uptake in people returning their bowel screening kits, which is the highest in the programme’s history. Do we have enough data about breast screening, bowel screening and other screening uptake and how that leads to the requirement for intervention? I am looking at Katie Cuthbertson, because I got most of that information from the centre for sustainable delivery.
