Cuisine & Edibility
Bluegill
Mild, sweet white flesh with fine texture and very low fat; one of America's most popular panfish for the table. Ideal pan-fried whole with cornmeal crust or deep-fried in strips.

Species Overview
Bluegill
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.
Discus
The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.
