About Flounder Fishing in Dauphin Island
A prized flatfish found along sandy bottoms and structure. Excellent table fare and fun to catch on light tackle.
Flounder are unique flatfish that lie camouflaged on sandy or muddy bottoms, ambushing prey from below. Gulf flounder and Southern flounder are the primary species in southern waters, while Summer Flounder (fluke) dominates from the Carolinas northward. Both eyes migrate to the top (left) side as juveniles, creating their distinctive flat profile. The "eyed" side is brown-green with irregular spots and blotches that change to match the surrounding bottom — a remarkable camouflage ability.
Scientific name: Paralichthys albiguttata

How to Catch Flounder in Dauphin Island
Techniques & Bait
Drifting live bull minnows (finger mullet or mud minnows) on a Carolina rig or knocker rig along sandy channel edges and drop-offs is the most productive method. Bounce a 1/4-3/8 oz jighead with a live minnow or Gulp! swimming mullet along the bottom near structure transitions (sand to mud, channel edges). "Flounder gigging" at night with underwater lights is popular in shallow bays. In passes and inlets, fishing the outgoing tide with live bait near the bottom produces the largest fish.
Recommended Tackle
Medium-light spinning rod (7 ft), 2500 reel, 10-15 lb braid, 20 lb fluorocarbon leader, 1/4-1/2 oz jig heads or Carolina rig with 1/0-3/0 wide-gap hooks. Patience is key — flounder often mouth the bait before committing, so wait for the second thump before setting the hook.
Best Inshore Fishing Spots in Dauphin Island
Top spots where local captains target flounder and other inshore species.
Mobile Bay
Mobile Bay is one of the largest estuaries on the Gulf Coast, with vast grass flats, oyster reefs, and river-fed marshes holding redfish, spotted seatrout, flounder, and sheepshead. The bay is famous for its "Jubilee" phenomenon when marine life pushes to shore en masse. The western shore along Dauphin Island and the eastern shore near Fairhope offer distinctly different inshore fishing experiences.
Pass aux Herons
Pass aux Herons is the shallow waterway between Dauphin Island and the mainland, serving as a vital tidal connection for Mobile Bay. Redfish, flounder, and spotted seatrout patrol the pass's grass flats and oyster bars on moving tides. The pass sees less boat traffic than the main bay, providing quieter fishing conditions and less-pressured fish.
Dauphin Island West End
The west end of Dauphin Island features a mix of beach, marsh, and tidal flats accessible by foot or kayak. Redfish, flounder, and pompano feed along the surf zone and in the sheltered back-bay waters. The island's western tip at Sand Island provides shore access to deeper water where Spanish mackerel and ladyfish are caught on light tackle.
Bayou La Batre Channel
The Bayou La Batre shipping channel on the mainland side opposite Dauphin Island cuts through productive marsh and oyster habitat. Redfish, spotted seatrout, and sheepshead hold along the channel edges and around shrimp boat docks. The area's working waterfront provides a uniquely authentic fishing experience on Alabama's Gulf Coast.
