Master the art of catching dolphin fish—aka mahimahi—with these proven techniques.

---

The dolphin fish is commonly called “mahi mahi,” their Hawaiian name, to avoid confusion with dolphin mammals. They are one of the most popular fish in the ocean because they fight hard, they have gorgeous coloration, and they make excellent table fare. What’s not to like?

Mahi are found world-wide in temperate offshore waters and grow quickly. They only live four- or five-years tops, and they are voracious feeders, so they can be easy to catch. But they sometimes refuse almost everything you throw at them, so here are a few tips to help find mahi offshore and get them to bite.

Look for Floating Debris Targeting Mahi Mahi

It’s common knowledge that mahi are often found under debris floating on the surface: weed lines, patches of weed, a floating tree limb, or even a floating bucket. Check out anything and everything you find floating in blue water, and always assume a fish or two might be there.

You can do this by simply stopping and looking, or if you don’t see them milling around under the flotsam, take a cast or two to make sure. Mahi love yellow bucktail jigs and they will also fall for a cut chunk of ballyhoo.

If you do pull up to some floating debris and see the tell-tale blue and green mahi colors below, have a Ziplock bag full of pre-cut ballyhoo chunks ready. Toss a few chunks and you can often trigger a feeding frenzy.

Then cast chunks on hooks and you can begin picking them off. Remember to always leave one hooked fish in the water until someone else hooks a second fish, then you can boat the first one. The school will stay with the hooked fish, almost always enabling you to catch a few before they lose interest.

Light Tackle for School Mahi

School-size mahi tend to run smaller, typically under 10 pounds, so light tackle works well for them. Eight-to 12-pound test spinning rods and reels are perfect for these school fish. Think 3500 to 4500 size reels with matching rods with a fast tip so you can cast to them.

No Debris? Use the Run-and-Gun Method

But what if there is no floating debris offshore? You can always troll for the fish using trolling feathers or rigged ballyhoo. But many savvy anglers prefer the “Run-and-Gun” method of locating mahi. That entails running around in the boat searching for signs of fish and then casting to them. Birds are the most common way these anglers find the mahi.

Frigate birds, often called “Man-O-War” birds, circle high in the air offshore using their keen eyesight to spot feeding fish below. When you see a frigate bird diving, always head straight to where they dove. That will often be mahi driving bait fish to the surface, where you can cast to them.

Targeting Bigger Fish

You’ll find the larger mahi under the birds, often as singles, pairs or a small school. Approach where you saw the birds diving carefully, making sure you get within casting distance but not too close where you risk driving the fish down. You’ll often see them on the surface chasing bait fish, and casting into that melee almost always results in a hookup.

If the bigger fish are there (you’ll see them) opt for stouter tackle. 12-pound test should be the minimum and 20-pound may not be too strong. Use appropriate rods like 4500 to 6500 size with matching rods.
