About the Mahi-Mahi

A spectacular pelagic species with brilliant colors. Mahi-Mahi are fast, acrobatic, and excellent eating. Found in open water around floating debris, weed lines, and offshore structure. Off Kona, the blue water starts close to shore.

How we hunt them

Mahi-Mahi are found around floating debris and weed lines offshore. They are curious and will often circle a diver. Use a long gun with a reel. They’re fast, so lead the shot slightly. Spring and summer are the best months, when warm blue water pushes in close to the Kona coast.
