Tackle & technique

King mackerel
Kings roam from beaches and pier ends out to reefs, wrecks and ledges in 40 to 200 feet, usually feeding in the upper half of the water column. Slow-troll live menhaden, blue runners or cigar minnows on a light wire stinger rig, or pull spoons and ribbonfish past bait schools. Look for clean green water above 68 F with bait and birds on it.
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.
Red drum
Redfish feed on shallow grass flats, oyster bars and marsh edges, often in 1 to 4 feet of water, and drop into channels, deep holes and tidal creeks when the water turns very hot or cold. Work a live shrimp under a popping cork or a soft plastic along the grass line on a rising tide, then fish creek mouths and drains as the tide falls. Bull reds over 30 inches school in the surf, passes and jetties in late summer and fall, where cut mullet or a live crab on the bottom is the standard approach.
