About Flounder Fishing in Port Mansfield
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 Port Mansfield
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 Port Mansfield
Top spots where local captains target flounder and other inshore species.
The Land Cut
The Land Cut is the narrow, dredged channel connecting the Upper and Lower Laguna Madre, running roughly 25 miles through some of the most pristine shallow-water habitat on the Texas coast. Redfish, speckled trout, and snook hold along the channel's grass-lined edges and in the adjacent shallow flats where the water clears to gin-clear conditions. Sight-casting to cruising redfish along the Land Cut spoil banks is one of the defining inshore fishing experiences in Texas.
East Cut Flats
The flats surrounding the East Cut jetties at Port Mansfield offer crystal-clear water over hard sand-and-grass bottom where redfish, speckled trout, and snook are sight-fished on light tackle. The East Cut's tidal exchange with the Gulf keeps the surrounding flats flushed with clean water and abundant bait, sustaining a world-class shallow-water fishery. Summer months bring snook into the mix, making Port Mansfield the northernmost reliable snook fishery on the Texas coast.
Laguna Madre Sand Flats
The endless sand flats of the Lower Laguna Madre surrounding Port Mansfield offer some of the clearest, shallowest sight-fishing water anywhere in the Gulf region. Redfish, speckled trout, and black drum feed over the white sand bottom, their shadows visible from great distances in the gin-clear water. This fishery demands stealth and precision casting but rewards skilled anglers with trophy fish and a sight-fishing experience rivaling any flats destination in the world.
Three Islands Area
The Three Islands area south of Port Mansfield features shallow grass flats surrounding a cluster of spoil islands that provide wind protection and concentrated fish-holding habitat. Redfish school around the island shorelines and on the surrounding flats, particularly during fall when large pods push onto the shallows to feed on mullet and shrimp. The islands serve as a natural waypoint and wind break that makes fishing possible even on days when open Laguna conditions are marginal.
