How and where it feeds

Water temperature
Feeds from 68°F to 86°F, best between 74°F and 82°F.
Water depth
100 to 10000 ft of water.
Structure
Bluewater, open water, ledge, canyon and bank, in that order of preference.
Tide and current
Prefers moving water, with light current.Tide stage is not a factor offshore. Mahi gather on floating sargassum weedlines, debris, buoys, FADs and current edges, so floating structure and warm clean water matter far more than tide.
Light
Some lift around dawn and dusk.
Pressure
Little response to pressure changes.
Wind and sea limits
20 kt of wind and 6 ft of sea. The Waterlands engine scores hours down as conditions pass them.

Tackle and technique

Mahi feed near the surface along weedlines, floating debris, buoys and current edges offshore, in water from the low 70s to the low 80s. Troll ballyhoo or small skirted lures along the weed, and when a school comes up behind the boat keep one hooked fish in the water while you pitch cut bait or jigs to the rest. Look for birds working over weed and flotsam.

Methods
trolling, sight casting, pitching bait to schools, chumming
Lures
skirted ballyhoo rigs, small feathers, plastic squid, bucktail jigs, spoons
Bait
ballyhoo, cut squid, sardine or pilchard chunks, cut bonito
