Mahi Mahi

Coryphaena hippurus · Coryphaenidae

Also known as: Mahimahi, Dolphinfish, Dolphin, Dorado

One of the fastest-growing fish in the ocean and among the most spectacular to look at. NOAA notes the brilliant colouring fades almost immediately after harvest.

Typical size
Most rod-caught fish are 5-25 lb
Max size
NOAA records them up to almost 7 feet and 88 pounds. They live up to 5 years and can exceed 4 feet in their first year.
Water
Saltwater
Best season
Warm months, following blue water and weed lines closer to shore.

Identification

Electric greenish-blue back, gold or sparkling silver lower body, and sides mixing dark and light spots. Males have a square, blunt head; females a rounded one.

Habitat & Range

Tropical and subtropical water near the surface, frequently around floating weed lines and debris. Juveniles school; larger males prefer open ocean.

The Atlantic, Gulf and Caribbean, caught from Massachusetts to Texas.

Diet & Feeding

A wide range, including small pelagic fish, juvenile tuna, invertebrates, billfish, jacks, pompano, and the pelagic larvae of nearshore bottom-living species.

Spawning & Reproduction

NOAA reports mahi mahi reach maturity at just 4 to 5 months old and are believed to spawn every 2 to 3 days through the spawning season, releasing 33,000 to 66,000 eggs each time. Because spawning is near-continuous rather than seasonal, no discrete spawning window is published here.

How to Catch

Keep one hooked fish in the water beside the boat and the rest of the school will often stay with it, giving everyone aboard a shot. Their extreme growth rate and five-year life mean populations turn over unusually fast.

Best techniques

  • Trolling weed lines and debris
  • Casting to visible fish
  • Live-baiting

Lures & baits

  • Trolled ballyhoo
  • Skirted lures
  • Live pilchards
  • Bucktail jigs

Best season: Warm months, following blue water and weed lines closer to shore.
