Cuisine & Edibility

Arapaima

Large, firm white fillets with a mild, clean flavor and low fat; historically a staple protein in Amazonian communities. Often salted and dried; sustainable harvest is tightly regulated.

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.

Species Overview

Arapaima

The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.

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.
