 Well, I love fish. I think it's one of the greatest foods on our planet. I'd be surprised if there was anyone here who didn't love tucking into a really beautifully cooked piece of fresh fish. I love to catch it. I love to cook it. I love to eat it. I love to feed it to my family. And I love to serve it at our cookery school and on the menu in our restaurants. But I think we all have to face up to the fact that the future of fish is highly uncertain. And this is what I set out to look into in these series. And obviously we needed some sort of rationale for looking at this very major problem. So we took the three most popular fish in the UK. We decided we had to get to the bottom of what were the fundamental sustainability problems of these three fish. And that would perhaps start to tell us where we were going wrong and how we might set off on a new footing to try and have a better relationship with fish.
