mahimahi

The mahi-mahi, Coryphaena hippurus, also known as the dolphinfish, is a surface-dwelling fish found in warm temperate and tropical oceans worldwide. It is part of the family Coryphaenidae and is commonly encountered around floating objects, weed lines, and in open-water habitats. The species is known for rapid growth and a short lifespan.

Physically, the mahi-mahi has a laterally compressed body with an elongated dorsal fin that extends along much of its back. When alive, it displays vivid iridescent colors—bright blues and greens—that fade after capture. Males and females reach up to about 1.5 meters in length and can weigh around 20–30 kilograms, though larger individuals have been reported. The fish is a fast, pelagic predator that feeds on squid, small fish, and crustaceans. It spawns multiple times per year in warm waters, with eggs that drift in the open ocean.

Fisheries and culinary use: The mahi-mahi is a popular target for commercial and recreational fishers due to its speed and fighting ability. It is commonly caught by trolling, handlines, and longlines. The flesh is light, firm, and white to pale pink, with a mild, sweet flavor and a high-fat content for a white fish, making it suitable for grilling, baking, and sashimi in some markets. Proper handling and freshness are important, as the flesh spoils relatively quickly in warm conditions.

Naming and notes: The name “mahi-mahi” is Hawaiian for “strong-strong,” reflecting the fish’s vigorous fight when hooked. In many markets the species is sold as mahi-mahi or dolphinfish, with regional preferences for labeling and preparation. Conservation measures in various regions aim to manage stocks and bycatch through regional management and quotas.
