Admittedly, I enjoy tuna on occassion when I am dining at a sushi restaurant.  Regardless, this photo still got me mad when I came across it on eater.  This is a 400 pound bluefin tuna being delivered at Bouley.  Market price is around $45/pound making this baby (and by baby i mean, juvenille as adults grow up to 12 feet and weigh as much as 1,500 pounds) is worth ~$18K by my calculations.  Seeing this photo reminded me of Charles Clover's "The End of the Line: How Overfishing is Changing the World and What we Eat"  I highly recommend the book as it opened my eyes about the state of the world's fisheries.  Here are two passages that I really enjoyed and found relevant:  

Nobody, I believe, should be knocking out a dozen servings a night of bluefin tuna, which is already in the anteroom to extinction. Least of all should anyone be treating the small and dwindling western Atlantic bluefin population as an unlimited resource. To put another way, how would you feel about a slice or two of mature endangered orangutan, served raw? If high-end restaurants did that I believe most movie stars would walk out rather than pose with the chef.

David Bouley was for many years New York's favorite chef, opening Montrachet, which rated three stars, in Tribeca in 1985 and the reliable Bouley in 1987. The latest version of Bouley has on its menu seared swordfish (though it doesn't say where these are from), Maine baby skate (can't he wait until they have spawned?), and Nova Scotia halibut (ICUN status: vulnerable). However much you admire Bouley for turning one of his restaurants into a canteen for Red Cross workers at ground zero in the wake of the Twin Towers atrocity, you do wonder if he has had time to catch up on other aspects of the news...
