Tackle & technique
- Mahi-mahi
- 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.
- Atlantic croaker
- Croaker feed on mud and sand bottom along channel edges, oyster bars, piers and deeper holes in bays and sounds, mostly in 5 to 30 feet of water. A two-hook bottom rig with small hooks and shrimp, bloodworm or squid catches them from piers, the surf and small boats. Fish the hours around high tide and into the evening.
- Spot
- Spot school over mud and sand in bays, tidal creeks and channels and around piers and bridges, generally in less than 25 feet of water. Fish a two-hook bottom rig with small hooks and bits of bloodworm or shrimp, and move until you find a school. In fall the biggest fish run out of the sounds past piers and inlets, and the bite can go all day.
