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 Sailfish
Firm, mildly flavored flesh similar to marlin; primarily a catch-and-release sport fish. Edible when smoked or grilled but rarely targeted for food; sport anglers typically release it.
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 Sailfish
The sailfish is the fastest fish in the ocean, reaching speeds up to 110 km/h. Its enormous dorsal fin, or 'sail,' can be raised to herd baitfish. When hooked, it performs spectacular tail-walking displays across the water surface.
