Physical Identification Features
Size & Weight
Mahi-mahi typically range from 20-40 inches in length, with mature fish commonly reaching 30-35 inches. They usually weigh 10-30 pounds, with exceptional specimens exceeding 50 pounds.
General Appearance
Mahi-mahi have laterally compressed bodies with brilliant gold, green, and blue coloration that changes rapidly. Males develop distinctive high, rounded foreheads (bulls) while females have more rounded heads (cows).
Distinguishing Features
Key features include the brilliant coloration, high dorsal fin extending the length of the body, deeply forked tail, and sexual dimorphism with males developing prominent foreheads.
Habitat & Distribution
Natural Environment
Mahi-mahi inhabit warm offshore waters, typically in tropical and subtropical regions. They're often found around floating debris, sargassum weed lines, and temperature breaks in open ocean environments.
Geographic Distribution
Found in tropical and subtropical waters worldwide, including the Atlantic, Pacific, and Indian Oceans. They prefer water temperatures above 70°F and are highly migratory.
Seasonal Patterns
Mahi-mahi spawn year-round in tropical waters, with peak spawning during warmer months. They make extensive migrations following warm water and food sources.
Behavior & Diet
Feeding Habits
Mahi-mahi are opportunistic predators that feed on flying fish, squid, crustaceans, and other pelagic prey. They're aggressive feeders that hunt both individually and in schools.
Activity Patterns
Most active during daylight hours with peak feeding periods during dawn and dusk. Mahi-mahi are attracted to floating objects and often travel with other pelagic species like tuna.
Fishing Tips & Techniques
Effective Techniques
Effective techniques include trolling with ballyhoo, squid, or artificial lures, live bait fishing around debris, and casting to visible fish. Look for floating debris, weed lines, and diving birds.
Recommended Gear
Medium to medium-heavy action rods, spinning or conventional reels, and 15-30 lb test line. Use wire leaders for larger fish. Popular lures include skirted trolling lures, spoons, and live bait rigs.
Conservation Status
Mahi-mahi populations are generally considered stable due to their fast growth and high reproductive rate. They're managed through size limits and bag limits in most areas.
