About the Mahi-Mahi

Mahi-Mahi (Coryphaena hippurus). Found in Offshore Weed Lines. Average length 36 in, weight 25.0 lbs. World record: 87.0 lbs (Papagayo Gulf, Costa Rica).

The Mahi-Mahi is one of the most recognizable saltwater species in North American waters, classified scientifically as <em>Coryphaena hippurus</em>. It belongs to the Offshore group, most commonly found in offshore weed lines environments. Anglers target this species for both sport and table fare, and it appears across a broad range of water bodies throughout the United States.

A typical Mahi-Mahi runs 36 inches in length and weighs around 25 pounds, though fish in prime habitat regularly exceed these averages. The all-tackle world record stands at 87 lbs, set at Papagayo Gulf, Costa Rica, making it a legitimate target for anglers chasing personal bests. Conservation status varies by region — check local regulations before keeping fish, as some waters have slot limits or catch-and-release requirements in place.

Habitat & Range

Primary habitat: Offshore Weed Lines.

The Mahi-Mahi thrives across a wide range of saltwater environments throughout North America. Seasonal movements are driven by water temperature — fish tend to move into shallower water during spring and fall feeding periods, and push deeper or seek cover during the heat of summer and cold of winter. Understanding these patterns is critical to locating fish consistently across the season.

How to Fish for Mahi-Mahi

Best bait: Ballyhoo.

Technique: Trolling.

Match your presentation to the season and conditions. In clear water, downsize your bait and slow your retrieve. In stained or muddy water, switch to high-contrast colors and add vibration. Early morning and evening are the most productive windows during summer months. During spawning season, fish become highly territorial and will strike out of aggression as well as hunger.

World Record

The all-tackle world record Mahi-Mahi weighed 87 lbs, caught at Papagayo Gulf, Costa Rica. This record represents the upper end of what this species achieves under ideal conditions. Most anglers targeting personal bests focus on proven trophy waters with the right combination of habitat, forage base, and light fishing pressure.

State Regulations

Regulations vary by state and water body. Before fishing for Mahi-Mahi, verify current size limits, bag limits, and open seasons with your state fish and wildlife agency. Check your state's fishing license requirements and season dates at the FishLog Fishing License guide.
