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.

Common Carp

Dense, moderately fatty flesh with an earthy flavor; improves greatly when sourced from clean, cold water. Central European staple — traditionally braised, fried, or prepared as gefilte fish.

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.

Common Carp

The common carp is one of the most widely introduced freshwater fish globally. Originally domesticated in East Asia over 2,000 years ago, it is a sacred fish in many cultures and the primary target species in European coarse fishing.
