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.
Zander
Lean, firm white flesh with a delicate, mild flavor and nearly no fat; boneless fillets are easy to work with. The most prized freshwater eating fish in Central and Eastern Europe.
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.
Zander
The zander is the European equivalent of the walleye and one of the most prized freshwater predators in Europe. Its excellent low-light vision makes it a crepuscular hunter. Its delicate white flesh is considered among the finest of freshwater fish.
