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.

Sockeye Salmon

Intense, deep-red flesh with a full, robust salmon flavor and high omega-3 content. Excellent grilled, smoked, or canned; its bold flavor stands up to strong seasonings and wood smoke.

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.

Sockeye Salmon

The sockeye salmon is famous for turning bright red during its upstream spawning migration. Its deep-red flesh is the richest in omega-3 fatty acids of all Pacific salmon species, making it the most valuable commercially.
