Species Overview

Crapet arlequin

The bluegill is the most common sunfish in North America and often the first fish a young angler catches. Its deep body, dark ear flap, and iridescent blue-green colors make it easy to identify. A fierce predator of insects despite its small size.

Esturgeon commun
