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.

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

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.

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.
