I am just trying to understand if the industry would invest in that.

So why was only one pen—the one that we went to visit—treated?

Okay. Is there something that happens that triggers that treatment, such as lice, gill health, morphological changes or something like that? What was the process? Those seven pens were treated over what period of time?

Out of how many fish in a cage?

For clarity, my question—

Yes, it is coming.

Ben, you were talking about the rate of applications; however, the industry has declared that it wants to double production by 2030. That is the root of my question. How can that be possible with the current rates of mortality, which would have to be halved in order for that overall number of dead fish to even stay at the 16 to 17 million dead per year? The idea is to increase and expand by 2030, but we are facing extreme mortality issues and a fluctuating climate. What more can we do, since it seems that the measures are not really helping?

At their largest size, say.

I have a brief supplementary question for David Brown, picking up on the question from my colleague Rhoda Grant about housing and infrastructure. Would Cooke Aquaculture Scotland, and the industry in general, be interested in supporting the call from Yell and Unst for fixed links to mainland Shetland? That is as an important element of the infrastructure, which I know that the salmon farming industry relies on.

So pen 1 was treated, but I think that there are seven pens there.

Thank you. I think that Ben Hadfield was talking about the daily routine—no, it was not Ben; it was David Brown.

It is good to see you again, David. You were talking about the daily routine, and you mentioned that 10 fish are taken. Is that from a whole farm or per cage?
