Cuisine & Edibility

Atlantic Cod

Iconic mild white flesh, low fat, and a flaky texture; the backbone of fish-and-chips and salt cod traditions worldwide. Currently Vulnerable; sustainable sourcing is strongly recommended.

Common Goldfish

Not consumed — a classic ornamental aquarium and pond fish; its vivid color and hardy nature make it one of the world's most popular decorative species.

Species Overview

Atlantic Cod

The Atlantic cod is one of the most historically important commercial fish species. Its mild, flaky white flesh has been a staple food in Europe for centuries. Overfishing caused the collapse of the Grand Banks fishery in 1992.

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.
