Mahi Mahi
Coryphaena hippurus
The fastest-growing fish in the ocean and one of the most colourful. Mahi gather under weed lines and floating debris, travel in schools, and strike trolled baits and cast lures with almost no hesitation.
Seasons · Peak
Identifying features
- Brilliant green, blue and gold colours that fade quickly after capture
- Blunt, steep forehead — high and squared on mature males (bulls)
- Long dorsal fin running from the head nearly to the tail
- Deeply forked tail and a thin, compressed body
- Look-alike: king mackerel is long and silvery with sharp teeth and no blunt forehead
Habits
- Fast, surface-oriented predator of flying fish and bait schools
- Travels in schools, often under floating weed or debris
- Feeds aggressively by day and rarely hesitates at a bait
- Migrates with warm currents; follows temperature breaks offshore
Distribution
Where to find them
- Sargassum weed lines and current rips offshore
- Floating logs, pallets and debris — even small pieces hold fish
- Colour changes and temperature breaks in blue water
- Around offshore buoys and bait schools, by boat only
Where they live
How to catch them
Trolling weed lines
Rig: Small skirted lure or rigged ballyhoo trolled at 6-8 knots
Bait/lure: Ballyhoo, small feathers in blue/white and pink
Key tip: Troll the clean edge of the weed line, not through the middle of it.
Casting to school fish
Rig: Spinning rod with a small jig or a hook baited with a chunk
Bait/lure: Cut bonito or squid chunks, small bucktails
Key tip: Keep one hooked fish in the water beside the boat — the school stays with it.
