Alan Alda in Scientific American Frontiers

Deep Crisis (#1306)

It's no accident that the ocean inhabitants we humans like to eat are the ones with the most uncertain futures. We follow efforts by biologists to figure out what's going on with salmon, once abundant on both East and West coasts of North America and now in catastrophic decline; and with the ocean-ranging giant bluefin tuna, which scientists have recently succeeded in tracking on its epic journeys between Europe and America.
