I remember what that self-sufficiency guru, John Seymour, said about raising free-range pigs, in as happy an environment that we could provide for them (which he did). I can't recall the exact quote, but he said that the good-life pig he'd grown for food that he was about to kill was happily munching away on roots one minute and in heaven the next. That's how we should think, I suppose, about wild ocean fish. I guess it takes them longer to die than John's pig, but it's hard to see how we could do it better. For me, it's no farmed fish, only wild, and fish only caught by sustainable methods that don't involve by-catch or wrecking the sea floor. That'll do me. Suit yourself.
