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.
- 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.
- Common snook
- Snook ambush bait around mangrove shorelines, bridge and dock lights, jetties and the mouths of passes and inlets, generally in 2 to 15 feet of water. Fish moving water, especially the outgoing tide, with a live pilchard, pinfish or shrimp, or a jerkbait or soft plastic swum past the structure. In summer they spawn along beaches and inlets, and in winter they crowd into rivers, canals and deep backcountry creeks where the water stays warmer.
