Cuisine & Edibility
Chinook Salmon
The largest Pacific salmon; exceptionally rich, fatty flesh with deep orange-red color and a full, buttery flavor. Superb grilled, smoked, or cured; the benchmark of Pacific salmon quality.
Discus
Not consumed — a prized ornamental aquarium fish known as the 'king of the aquarium' for its disc-shaped body and brilliant colors.
Species Overview
Chinook Salmon
The chinook salmon, also known as king salmon, is the largest of the Pacific salmon species. It undertakes epic migrations from the ocean to its natal river to spawn once before dying, providing nutrients to the entire watershed ecosystem.
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.
