Soft, oily flesh with a rich, pronounced flavor and high omega-3 content. Culturally essential across Northern Europe — pickled, smoked, salted, or prepared as Bismarck herring or rollmops.
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 Herring
The Atlantic herring is one of the most abundant fish species on Earth, forming massive schools of billions of individuals. It has played a crucial role in European history, fueling trade routes and even wars.
