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.
Atlantic Salmon
Rich, buttery flesh with high omega-3 fat content and a distinctly full flavor. Versatile in the kitchen — superb grilled, poached, smoked, or served raw as sashimi.
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.
Atlantic Salmon
The Atlantic salmon is an anadromous species that migrates from the ocean to freshwater rivers to spawn. Renowned among fly fishers, it is also one of the most important farmed fish species globally.
