European Eel

Rich, fatty flesh with a distinctive earthy flavor; classically smoked, jellied (in Britain), or grilled kabayaki-style. Critically Endangered — consumption strongly discouraged; population down 90%.

Species Overview

Common Goldfish

The goldfish was one of the first fish to be domesticated, with selective breeding in China dating back over 1,000 years. Despite common misconceptions, goldfish can live 10-15 years with proper care and require far more space than a small bowl.

European Eel

The European eel undertakes one of nature's most remarkable migrations, traveling 5,000 km from European rivers to the Sargasso Sea to spawn and die. Despite centuries of study, its breeding grounds were only recently confirmed.
