Mahi-Mahi
Mahi-mahi range across tropical and subtropical oceans worldwide — Atlantic, Pacific, and Indian — following warm currents and floating structure from the surface down.
One of the fastest-growing fish in the sea, they can put on roughly an inch a week and reach 30 pounds before most freshwater species hit double digits.
That combination of electric color, acrobatic runs, and table quality makes them one of the most pursued offshore targets on the planet.
Scientific Name: Coryphaena hippurus
Also known as Dolphinfish, Dorado, Common dolphinfish, Dolphin
- Electric greenish-blue back fading to gold and silver flanks with scattered dark and light spots — coloration that flashes brilliantly in the water but fades to uniform grey-silver within seconds of death.
- A single long dorsal fin runs nearly the full length of the back, from above the eye almost to the tail — no other common offshore pelagic shares this profile.
- Adult males (bulls) have a nearly vertical, squared-off forehead; females (cows) have a rounded, sloping head — the easiest field distinction between sexes.
- Commonly caught at 3 feet and 30 lbs; can reach 6 feet and 88 lbs. The IGFA all-tackle record is 87 lbs.
What to know
Habitat Distribution
- A wide-ranging pelagic species native to tropical, subtropical, and temperate waters across the Atlantic, Pacific, and Indian Oceans — one of the most globally distributed offshore fish.
- Surface-oriented, typically holding in the top 5–10 meters of the water column, though they can be found down to around 85 meters.
- Highly migratory, following warm-water currents — including the Gulf Stream in the Atlantic — into temperate latitudes during warmer months and retreating as temperatures drop.
Specific Spots
- Any floating object — sargassum weed lines, lobster pot buoys, floating timber, debris — concentrates baitfish and juvenile fish, which in turn hold mahi underneath and around the edges.
- Juveniles live almost exclusively in sargassum mats; working the edges and pockets of large weed lines is the most reliable way to find schooling fish.
- Active surface schools give themselves away with visible boils and baitfish spray — when you see birds working or bait scattering, the fish are already there.
Mahi-Mahi FAQ
Answers from onWater's species guide.
What are the best lures and bait for Mahi-Mahi?
Trolling with skirted lures, feather jigs, or swimming plugs rigged ahead of or behind ballyhoo covers the most water and is the standard way to locate fish in open ocean.
What flies work for Mahi-Mahi?
Large, flashy streamers, Lefty's Deceivers and epoxy baitfish patterns that imitate flying fish or small pelagic baitfish, are the core mahi fly. Size up (4–6 inches) and add plenty of flash; these fish key on movement and profile in open water.
What do Mahi-Mahi eat?
Small pelagic baitfish, flying fish, juvenile tuna, jacks, and triggerfish, make up the bulk of the diet, which is why large, fast-moving baitfish imitations (skirted trolling lures, Deceivers, Clouser Minnows) are the go-to starting point.
Where do Mahi-Mahi live?

Surface-oriented, typically holding in the top 5–10 meters of the water column, though they can be found down to around 85 meters.
