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