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.
Northern Pike
Lean white flesh with a mild, slightly earthy flavor; notable for Y-shaped pin bones that require careful filleting. Excellent in fish cakes, fried, or baked with herbs.
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.
Northern Pike
The northern pike is an apex predator of freshwater lakes and rivers across the Northern Hemisphere. With its elongated body, duck-bill snout, and razor-sharp teeth, it ambushes prey with explosive bursts of speed.
