The wonder of the marine world is in serious danger

Streamlined, musclebound, warm-blooded and with fins that retract into body slots like a switchblade so it can attain swimming speeds of more than 40 mph, the Atlantic Bluefin Tuna is a wonder of the marine world – the Clan Chief of the Scombridae, that can weigh up to 1,500 lb. It has long been prized by sport fishermen, from Charlie Chaplin to the dentist-turned-bestseller Zane Grey, and there is nothing tentative about a tunny strike. In 1927, after a four-hour battle with one eight-foot giant, Grey wrote: ‘If it were possible for a man to fall in love with a fish, that was what happened to me. I hung over him, spellbound and incredulous.’

Alas for the ABT (as they are known in the trade), they taste so good that they have been hunted for millennia.
