Fishing for Tuna

The Atlantic bluefin tuna, Thunnus thynnus, is one of the most valuable animals in the world. Its commercial value in the Asian sushi and sashimi markets can be as high as $60,000 each for giant tuna. Recreational fishermen on the Atlantic coast pay top dollar for offshore charter boats seeking bluefins. Frequenting the offshore sand ridges and canyons of the continental shelf and slope, these fish are often found wherever there is mixing of cold and warm currents. Off Maryland’s coast, this can be thirty or forty miles offshore.
