Cuisine & Edibility

Black Crappie

Sweet, tender white flesh with fine flakes and very low fat; considered among the best-tasting panfish. Delicious pan-fried with light seasoning or battered and deep-fried.

Discus

Not consumed — a prized ornamental aquarium fish known as the 'king of the aquarium' for its disc-shaped body and brilliant colors.

Species Overview

Black Crappie

The black crappie is a popular panfish found throughout North American lakes and reservoirs. Known for its delicate, sweet-tasting flesh, it is most actively caught during spring spawning when it moves to shallow water near cover.

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.
