Tackle & technique

Crevalle jack
Jacks roam in schools through inlets, passes, bays, river mouths and along beaches, pushing bait to the surface, and big fish also hold on nearshore reefs and wrecks. Watch for birds and surface blowups, then cast a popper, a spoon or a bucktail into the school and retrieve fast. Bring heavy spinning tackle, because a jack over 15 pounds runs hard and fights for a long time.
Gray triggerfish
Gray triggerfish hover a few feet over reefs, wrecks and ledges, usually in 60 to 200 feet, and often show up while snapper fishing. Use small, strong circle hooks with small pieces of squid or cut bait on a short bottom rig, because they nibble and strip big baits. Keep the bait just off the bottom and reel steadily at the first solid pull.
Red snapper
Red snapper school over rigs, wrecks, artificial reefs and natural ledges, mostly in 60 to 250 feet. Anchor or drift over the structure, chum, and drop cut or live cigar minnows, sardines or squid on circle hooks, using as little weight as the current allows. Federal rules require circle hooks with natural bait in the Gulf and a descending device or venting tool on board.
