Cuisine & Edibility
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.
European Sturgeon
Critically Endangered — consumption is illegal throughout its range. Historically prized for its delicate flesh and black caviar; now one of the world's most threatened fish species.
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 Sturgeon
The European sturgeon is a critically endangered anadromous fish that can live over 100 years. Once abundant in European rivers, it is now restricted to a small population in the Gironde estuary. Its eggs are harvested as beluga-grade caviar.
