Mahi Mahi Fishing: Complete US Guide
The mahi mahi (also called dolphinfish or dorado) is one of the most spectacular offshore gamefish in American waters. With its electric blue, green, and gold coloring, blistering speed, and aerial acrobatics, the mahi is a thrill on every hookup. These fast-growing pelagic fish travel in schools under floating debris, weed lines, and FADs (fish aggregating devices), making them relatively accessible for offshore anglers. Add in world-class table fare, and mahi are the complete package.

Step-by-Step
How to Catch Mahi Mahi
A practical guide for weekend anglers, from choosing your method to landing your catch.
- 1
Find the floating stuff
Mahi congregate under floating debris: weed lines, boards, pallets, buoys, and FADs. Run offshore and scan the horizon for anything floating. Where there is structure, there are usually mahi. Current edges and temperature breaks also concentrate fish.

Troll rigged ballyhoo
The classic mahi technique is trolling rigged ballyhoo under a sea witch or chin-weighted rig at 5–8 knots. Run lines at various distances: short rigger, long rigger, and flat lines. Most charter boats ($800–$1,500 per trip) use this method.
- 3
Keep the school near the boat
When you hook a mahi, leave the fish in the water while others cast to the school. Mahi are social, and the school will stay near a hooked fish. Have spinning rods rigged with jigs or live bait ready to pitch for multiple hookups.

Cast poppers and jigs for schoolies
School-size mahi (2–10 lb) are a blast on light spinning tackle. Cast small poppers, bucktail jigs, or live pilchards to fish under weed lines and flotsam. A medium spinning rod with 20 lb braid handles them perfectly.

Frequently Asked Questions About Mahi Mahi Fishing
Typically 10–50+ miles offshore, depending on where the current edge and warm water are. In South Florida, the Gulf Stream runs close to shore, so mahi can be found as close as 3–5 miles out. In the Carolinas, you may need to run 30–50 miles.
A charter is the easiest way to get into offshore fishing. Half-day trips run $600–$1,000 and full days $1,000–$1,500+ depending on the port. If you own or rent a center console (20+ ft), you can target mahi independently with the right safety gear and electronics.
Mahi is one of the finest eating fish in the ocean with firm, white, mildly sweet flesh that is incredibly versatile. Grilled mahi tacos, blackened mahi, and pan-seared with mango salsa are all outstanding. Fresh mahi from the boat is a world apart from store-bought.
Mahi are one of the fastest-growing fish in the sea. They can reach 40+ lb in just 2 years. This rapid growth rate makes them relatively sustainable to harvest, which is why bag limits are generous (typically 10 per person per day in federal waters).
The mahi season in South Florida runs from April through September, with May and June being the peak months for numbers and size. The spring run often produces the biggest fish, including 30–50 lb bulls.
Mahi are attracted to bright colors. Chartreuse, pink, blue/white, and green/yellow are the top trolling lure colors. For casting jigs and flies, anything bright and flashy works. Match the size to the baitfish in the area.
