Cuisine & Edibility
Atlantic Bluefin Tuna
The pinnacle of raw fish dining — intensely rich, fatty tuna-o-toro with deep red color and buttery, umami-forward flavor. Commands the highest prices globally in Japanese sushi markets.
Spotted Seatrout
Soft, delicate white flesh with a mild, sweet flavor; low fat and best eaten fresh. A Gulf Coast favorite — excellent pan-fried, baked with Cajun spices, or used in fish tacos.
Species Overview
Atlantic Bluefin Tuna
The Atlantic bluefin tuna is one of the largest bony fish, capable of crossing the Atlantic in under 60 days. A single specimen has sold for over $3 million at Tokyo's fish market. It can maintain a body temperature above the surrounding water.
Spotted Seatrout
The spotted seatrout, despite its name, is a member of the drum family, not the trout family. It inhabits grass flats and estuaries along the Atlantic and Gulf coasts. Males produce a distinctive drumming sound to attract females.
