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.
Walleye
Considered one of the best-tasting freshwater fish; sweet, flaky white flesh with very low fat. Ideal pan-fried, battered, or baked — a North American culinary favorite.
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.
Walleye
The walleye is the largest member of the perch family and the most sought-after freshwater food fish in North America. Its reflective eyes give it exceptional low-light vision, making dawn and dusk prime feeding times.
