About King Mackerel Fishing in Grand Isle
Also called Kingfish. A fast, hard-fighting fish found near reefs and wrecks. Popular for smoking.
King Mackerel — called "Kingfish" or "Kings" — are fast, hard-fighting predators found from the Gulf to the mid-Atlantic. These streamlined fish are built for speed, with a silver body, iridescent blue-green back, and a deeply forked tail. The lateral line dips sharply downward below the second dorsal fin, distinguishing kings from similar species. They are voracious feeders that attack bait at incredible speed, making hookups explosive.
Scientific name: Scomberomorus cavalla

How to Catch King Mackerel in Grand Isle
Techniques & Bait
Slow-trolling live bait is the classic technique — rigging large live blue runners, goggle-eyes, or threadfin herring on stinger rigs (a lead hook through the nose and a trailing treble near the tail) and slow-trolling near reef edges, wrecks, and temperature breaks. Dead bait (cigar minnows, ribbonfish) rigged on king mackerel "stinger" rigs trolled with a duster or sea witch produce well. Casting live bait to visible surface-feeding schools is exciting. Fast-trolling with spoons (Drone, Clark) and planers covers water efficiently.
Recommended Tackle
Medium-heavy spinning or conventional rod (7 ft), 5000+ reel, 20-30 lb braid, long wire leader (single-strand #5-#7 or multi-strand wire — kings have razor teeth that cut fluorocarbon).
Best Nearshore Fishing Spots in Grand Isle
Top spots where local captains target king mackerel and other nearshore species.
Grand Isle Fishing Pier
The Grand Isle State Park fishing pier extends into the Gulf from the island's eastern end, providing shore access to nearshore Gulf species. Spanish mackerel, pompano, redfish, whiting, and jack crevalle are caught from the pier during seasonal runs. The pier is one of the most productive shore-fishing locations on the Louisiana coast.
Grand Isle Nearshore Platforms
Numerous oil and gas platforms stand within 3-15 miles of Grand Isle in 30-70 feet of water, acting as massive artificial reefs. Red snapper, mangrove snapper, cobia, sheepshead, and triggerfish stack up around the platform legs year-round. The density of platforms in Louisiana's nearshore waters provides more fish-holding structure than nearly any other coastal area.
Barataria Pass Jetties
The rock jetties at Barataria Pass create excellent nearshore structure where the pass current meets the Gulf. Sheepshead, redfish, flounder, cobia, and Spanish mackerel congregate along the jetty rocks on tidal changes. The jetties are accessible from shore on Grand Isle's east end and are a favorite spot for both visiting and local anglers.
Grand Isle Surf Zone
Grand Isle's south-facing Gulf beach offers productive surf fishing for pompano, whiting, redfish, and bull reds during fall and winter. The beach's gentle slope and shell-bottom breaks create feeding zones where fish cruise the trough between sandbars. Surf fishing Grand Isle during the fall rodeo season is a Louisiana Gulf Coast tradition.
