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.

Northern Pike

Lean white flesh with a mild, slightly earthy flavor; notable for Y-shaped pin bones that require careful filleting. Excellent in fish cakes, fried, or baked with herbs.

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.

Northern Pike

The northern pike is an apex predator of freshwater lakes and rivers across the Northern Hemisphere. With its elongated body, duck-bill snout, and razor-sharp teeth, it ambushes prey with explosive bursts of speed.
