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.

黃鱸

Sweet, clean white flesh with very low fat and a delicate texture; among the most prized freshwater eating fish in the Great Lakes region. Best pan-fried or sautéed simply in butter.

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.

黃鱸

The yellow perch is a schooling fish found in lakes and slow rivers across North America. Its golden-yellow body with dark vertical bars is unmistakable. Its sweet, firm white flesh makes it one of the finest-tasting freshwater fish.
