On the water

WhenSpring through fall, but THE event is the fall flounder run (Oct-Nov): flounder migrate from the bays out through passes/jetties to spawn, stacking at cuts, jetties, San Luis Pass and the dike - best on strong outgoing tide. Note the Nov 1-Dec 14 statewide closure caps the tail of the run.WhereSandy/muddy bottoms near structure and current edges: bayou and channel mouths, drains and cuts, the jetties and rock, the Texas City Dike, San Luis Pass, marsh drains, pier and bulkhead pilings, and drop-offs along the Intracoastal.HowSlow-drag baits on bottom right along structure and drop-offs; hop a jig/soft plastic slowly on the bottom; drift live mud minnows/finger mullet on a Carolina rig near cuts. Give a slow sweep - flounder grab and hold, so pause before setting the hook. Gigging at night is a Galveston tradition (subject to the closure).BehaviorLie-in-wait ambush predators that bury in sand and inhale bait passing overhead. They pin along current-swept structure during the migration, intercepting shrimp and finger mullet funneled through the cuts.The fightModest - dead-weight resistance and stubborn head-shakes; a big doormat can flare in current. The soft take is the real challenge, not the fight.

Baits that work

Tackle

Rod & reel7' medium/medium-light spinning or baitcaster with a sensitive tip, 2500-3000 reel.Line10-15 lb braid (sensitivity to feel the soft bite).Leader15-20 lb fluorocarbon, 18-24".Terminal1/8-3/8 oz jigheads; 1/0-3/0 kahle or wide-gap hooks for live bait; 1/4-3/4 oz egg sinker.RigCarolina/fish-finder rig with a light egg sinker; jighead with soft plastic dragged on bottom; drop-shot near pilings.

The bait clock

☀ DawnMud minnow or Gulp! shrimp on 1/4 oz jighead
Work drains and points early as bait exits marshes on the falling tide.
☼ MiddayGulp! swimming mullet bounced slowly on bottom
Flounder are ambush feeders that bite all day; slow-dragged scented plastics cover drop-offs.
☾ DuskLive finger mullet on Carolina rig
An easy meal drifted past channel edges as flounder reposition on the evening tide change.
★ NightGigging with lights in calm shallows (not rod-and-reel)
Night flounder harvest in Galveston is a gigging fishery; hook-and-line bite is poor after dark.

[{'months': [10, 11], 'note': 'Fall run to the Gulf: passes and jetties stack fish; mud minnows/finger mullet excel (Nov harvest rules apply).'}]

Tide stage and bottom structure matter far more than time of day for flounder.

Don’t confuse it with

Gulf Flounder

Southern flounder are the usual target — mottled without distinct eye-spots. A Gulf flounder shows three prominent dark ocellated spots in a triangle. Same limit, but know what you've got.

Keep or release

Handling & releaseHardy on the bottom, but often deep-hook because they hold bait; use wide-gap/circle hooks and set slow to improve release. Undersized and closure-period fish must be released - get them back quickly.On the tablePrized flatfish - thin, white, delicate and sweet fillets, mild with fine flake. Great whole-stuffed/baked, pan-fried, or fried. Among the best-eating inshore fish on the Texas coast.As baitA gamefish/table fish, not used as bait. Its own preferred baits are mud minnows and finger mullet.
