Mahi-Mahi Fishing Guide

Mahi-mahi (Coryphaena hippurus) are among the most spectacular and colorful fish in the ocean — alive, they display an electric display of blues, greens, and golds that fades to yellow-gray within minutes of death. They are extraordinarily fast-growing fish, reaching sexual maturity in 4–5 months and growing over 2 pounds per week under ideal conditions. The blunt, rounded forehead of males (bulls) distinguishes them from females (cows), which have a more streamlined head profile. Mahi are strongly associated with floating objects — sargassum weed lines, floating debris, crab trap buoys, and FADs (fish aggregating devices) — where they congregate to prey on the small fish and crustaceans living beneath. The world record is 87 pounds, but typical fish run 5–25 pounds, with fish over 40 pounds ('slammers') being notable trophies.

Mahi-Mahi is a saltwater species.

Habitat

Tropical and subtropical offshore waters of all major oceans, between the 68°F isotherms; in US waters, most abundant off South Florida, the Gulf of Mexico, Hawaii, and the Gulf Stream corridor from Florida to North Carolina. Pelagic and surface-oriented, found in the top 300 feet; concentrated at temperature breaks, color changes, and floating debris lines.

Diet

Flying fish, squid, small tuna, and crustaceans living beneath floating weed lines and debris. Mahi are aggressive, opportunistic feeders that attack virtually any fast-moving lure or bait — their willingness to eat combined with their acrobatic fight and table quality make them one of the most sought offshore species.
