There's a great article from the Sunday New York Times Magazine by Paul Greenberg, The Catch, about Chilean Sea Bass (aka Patagonian toothfish) and the over fishing of our oceans. It's an interesting, and rather depressing, examination of attempts to protect and restore fish stocks in the face of increasing consumer demand and illegal fishing activity. It's long, but well worth reading, though it may make you feel bad about eating fish after you're through.
