About Cobia Fishing in Grand Isle
A powerful, curious fish often found near buoys, rays, and structure. Excellent eating and hard fighters.
Cobia are powerful, unique gamefish that look like nothing else in the ocean — a flat, broad head, single dorsal fin, and dark brown coloring with a distinctive black lateral stripe running from head to tail, with lighter stripes above and below. They are often found near buoys, rays, sea turtles, and other large objects, using them as shade and ambush cover. Cobia are curious fish that will approach boats, and sight-casting to cruising cobia is one of the most exciting experiences in inshore/nearshore fishing.
Scientific name: Rachycentron canadum

How to Catch Cobia in Grand Isle
Techniques & Bait
Sight-casting to cobia following rays or cruising near buoys is the premier technique — throw a live eel, large live crab, or large jig directly in front of a cruising fish. Live eels are the #1 bait. Large jigs (1-2 oz) in brown, white, or chartreuse bounced near structure work well. Chumming with cut baitfish over wrecks and reefs draws cobia up from the bottom. During the spring migration, anchoring near channel markers and buoys with live bait (pinfish, crabs) catches fish as they migrate along the coast.
Recommended Tackle
Medium-heavy spinning or conventional rod (7 ft), 5000-6000 reel, 20-30 lb braid, 40-60 lb fluorocarbon leader, 5/0-7/0 circle hooks. Cobia make blistering initial runs — make sure your drag is set properly.
Best Nearshore Fishing Spots in Grand Isle
Top spots where local captains target cobia 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.
