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.

Mahi-mahi

Firm, slightly sweet flesh with large, moist flakes and low fat. Excellent grilled, blackened Cajun-style, or in tacos; one of the most popular sport fish for the table.

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.

Mahi-mahi

The mahi-mahi, also known as dorado or dolphinfish, is among the most colorful pelagic fish in the ocean. Its iridescent blue, green, and gold body fades rapidly after death. It is a fast-growing species, rarely living beyond five years.
