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.

Smallmouth Bass

Clean, white, mildly flavored flesh with low fat; considered slightly firmer and more flavorful than largemouth bass. Excellent pan-fried or baked; a respected table fish in the Great Lakes region.

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.

Smallmouth Bass

The smallmouth bass is widely considered the best-fighting freshwater fish pound-for-pound. Found in clear, rocky streams and lakes, it is more athletic and acrobatic than its larger cousin, the largemouth bass.
