My Lords, I do not support the amendment, which does not seem practical. Of course, there has to be liaison—that I understand—but not a co-ordinated policy. I will quote one example, because I asked for some briefing about what has happened in the sea with a particular species. As colleagues will know, the International Council for the Exploration of the Sea provides annual catch advice, and gave me an example against the criteria of how much movement there really is in any one particular species of fish. The example it gave me was the north-east Atlantic mackerel situation: in 2017, the catch advice was 944,302 tonnes. That dropped in 2018 to 550,948—a 42% reduction—and in 2019, initial advice, based on the best science available at the time, was 318,403 tonnes, revised in mid-year to 770,000 tonnes—an increase of 140%.
The council has emphasised to me that, while it welcomes enormously the change to scientific advice from the former situation which pertained in the EU, the science has an awfully long way to go and is highly variable. In that situation, it seems that it is a big enough challenge for our own people, particularly the management that is running our fishing fleets and doing the fishing, to get a grip of this and plan for that. It is inappropriate to proscribe in primary legislation to the depth that this amendment seeks. This industry is even more variable than the agricultural industry—I know we have spoken about that on earlier occasions. I also look at the history of the horticultural world, which I know quite a lot about and, my goodness, it does not have to face what the poor fishing industry has to face. On balance, therefore, I am afraid that I find little favour in this amendment.
