The Most Spectacular
Game Fish in the Pacific

Aloha, and welcome to mahi mahi fishing Kauai style. Mahi Mahi — also called Dorado, or dolphin fish on the US mainland — is one of the most spectacular game fish in the Pacific, glowing electric gold, green, and blue when they're alive and fading to silver within minutes of leaving the water. Kauai's offshore ledges are loaded with them.

Mahi Mahi fishing in Kauai is one of the most reliable big-game experiences we offer on the Emma Nalani, our 41-foot Bertram six-pack sport fishing yacht. Every mahi mahi charter Kauai runs starts at our dock at Nawiliwili Small Boat Harbor, where the ocean drops a thousand feet a quarter mile from shore — and that's exactly where mahi live.

  • Mahi Mahi are one of the fastest-growing fish in the ocean, reaching 30+ lbs in a single year
  • Kauai catches typically run 10 to 40 lbs, with bulls (males) over 50 lbs not uncommon
  • They travel in schools, often in pairs, and frequently gather under floating debris, weedlines, and bird activity
  • Mahi Mahi hit hard, fight wild, and put on aerial displays that make them a crowd favorite
  • The all-tackle IGFA world record stands at 87 lbs (caught off Costa Rica)
30 lbs in one year
Mahi Mahi fishing in Kauai delivers on every angler's checklist — visual strikes, hard fights, jumping fish, and sashimi-grade dinner all rolled into one trip. That's why we call it one of the best all-around Kauai fishing experiences we run.

When and Where to Catch
Mahi Mahi in Kauai

Mahi Mahi fishing in Kauai runs year-round, with peak season falling in spring and summer when water temperatures are at their warmest. Mahi are opportunistic pelagics that follow warm water, bait, and floating structure — so the best fishing sometimes happens on a random week when a school finds a weedline off the coast.

Offshore Structure & Flotsam

Mahi love anything floating. Debris, weedlines, buoys, logs, and even a single palm frond can hold an entire school underneath.

🐦
Under Working Birds

Frigate birds and terns diving on bait schools often sit directly over mahi. A working bird is one of the most reliable tells on the water.

🌊
The 40-Fathom Ledge and Beyond

Accessible on any of our trip types, from the half-day on up. The geometry of Kauai's shelf puts us in mahi water fast.

The Short-Trip Fish

Mahi are a classic Kauai short-trip fish. The best mahi mahi fishing charter Kauai option for most guests is a 4-hour half-day charter — which is often all you need to put multiple mahi in the box. When to catch mahi mahi in Kauai mostly comes down to getting on the water on the right week, which is why deep sea mahi mahi fishing Kauai Hawaii style works so well on shorter trips too.

How We Fish for Mahi
on the Emma Nalani

Mahi Mahi fishing on the Emma Nalani typically starts with trolling skirted lures and rigged ballyhoo at 6 to 9 knots behind the boat. Once a mahi is hooked, our crew often leaves it in the water briefly — because mahi travel in schools and their schoolmates will often swim right up to the boat.

That's when you'll see anglers hooking multiple mahi in quick succession, a phenomenon known on the dock as a "mahi blitz."

  • Medium-heavy trolling rods with Penn International Gold 2-speed reels, rigged with 50 to 80 lb line
  • Skirted lures, rigged ballyhoo, and cedar plugs running behind the boat
  • Outriggers to spread the spread and cover more water
  • Light tackle on the troll, ready to switch to casting if we find a school stacked under flotsam

Mahi Mahi are aggressive eaters — the strike is violent, the first run is wild, and the aerial jumps are what make these fish one of the most photographed catches on any Kauai fishing charter. Even novice anglers tend to land mahi successfully, which is part of why a half-day or three-quarter-day fishing charter is the perfect window to hunt them.
