Ollie:
Great post that you did! You are indeed cutting into the core of the matter.
My initial post suggesting the preservation of more aquatic habitat around the globe may have been a knee-jerk reaction, after being so moved by a quality National Geographic article. But the concept of more effective conserving must somehow be properly constructed, so that we do not suffer the layers of abuse, as you have so well posted.
This is really the heart of the matter that I am saying we must address; hopefully, as a gang of unified fishermen.
I have also carefully read that intersting article in Florida Sportfishing

Magazine (diabolically opposed to preserve areas, but citing other good conservation measures as the better solution) and I can equally agree with that counter-culture to the preserve topic.
So this may not be the perfect solution or even the proper solution but I hope we can agree that we must start clamouring for a still better plan. (The Bluefin tuna tragedy just makes the point in SCREAMING LETTERS.) NMFS, may have its faults, but it is our official domestic management unit, of course on the NATIONAL level, as the namsake states, so we must influence it, from the grassroots foundation of our society, to vigilently petition the right thing to do. And gaining traction at ICCAT at the International level, seems to be a very high priority, if we have any hopes to consserve our planet from those that have those greedy eyes, and the means to achive success at achieving the greed.
I agree that the collapse of a fishery is certainly a great regulating equilizer. But as I see it there are a lot of people out there that still want to eat Bluefin tuna regardless of whether there is a collapsed fishery or not.
So we need to be sure that we protect ourselves from ourselves. At this point, it is clear that the Bluefin tuna do not even have a vote. We simply we to eat them. But I sure would not be to happy to see them go extinct on my watch. (Somehow, I seem to think of Dr. Bill Hogarth saying those exact same words at some point in time within his office.)
So this is great discussion and some good ideas may evolve from them. Perhaps in a twist of words: THOUGHTS FOR SUSTAINED FOOD.
