Mahi-Mahi

The name confusion

The fish has several names, all referring to the same species:

• Mahi-mahi — Hawaiian name, now standard in restaurants and most retail.
• Dolphinfish or just “dolphin” — historical English name, now mostly avoided to prevent confusion with dolphin mammals.
• Dorado — Spanish-speaking countries.
• Calitos — some Caribbean uses.

The “mahi-mahi” branding (Hawaiian for “strong-strong”) deliberately replaced “dolphinfish” in the 1980s after diners began objecting to ordering anything called “dolphin.”

Fast-growing fish

Mahi-mahi grow at extraordinary rates — reaching maturity at 4–5 months and full adult size (1–2 m, 7–15 kg) within a year. Most live 4–5 years total. The fast generation time makes the species relatively resilient to fishing pressure, and most mahi-mahi fisheries are considered well-managed (Marine Stewardship Council certified in some regions).

Visual spectacle

Living mahi-mahi are stunning — iridescent blue-green-yellow flanks with golden bellies, the colors flickering as the fish moves. Adult males develop a distinctive blunt forehead (the “bull”); females have rounded heads.

The vibrant colors fade rapidly after death — the fish loses much of its color within minutes of being landed. Photographs of fresh-caught mahi-mahi rarely capture the living fish’s full coloration.

In the kitchen

Mahi-mahi flesh is firm, mild, slightly sweet, with low oil content. It holds up well to direct grilling, blackened seasoning, fish tacos, and ceviche — but it’s lean enough to dry out if overcooked. Treat like a tuna steak: cook quickly, leave the center slightly translucent.
