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.

Brown Trout

The brown trout is native to European rivers and has been introduced worldwide. Renowned for its wariness and intelligence, it is the ultimate quarry for fly fishers. Larger specimens become nocturnal, feeding primarily on smaller fish.
