Season by region

Where to find them

Marsh drains and bay shorelines, passes and jetties as fish head for the Gulf in fall (TPWD).

On the bottom along trough edges, close to shore, and near inlets.

What to look for

Sand edges and drop-offs where bait gets swept, mullet schools moving along the beach. Southern flounder have no distinct eyespots; summer flounder show five and Gulf flounder three.

What to throw

Bucktail or jighead with a 4 to 5 in paddle tail1/2 to 1 oz, 4 to 5 in tail. Slow hops along the bottom: lift, drop, let it touch, repeat.

Jighead with a scented soft-plastic shrimp or mullet (Gulp style)1/4 to 1/2 oz, 3 to 4 in. Slow drag and hop on the bottom with pauses; scent does the work.

Gold spoon (weedless style)1/2 to 3/4 oz, 2.5 to 3 in. Slow to medium wobble with occasional pauses near the bottom of the trough.

Bait

Live finger mullet (4 to 6 in), Mud minnows. Carolina rig, 1 to 2 oz egg sinker, 18 to 24 in of 20 to 30 lb fluorocarbon, 1/0 to 3/0 hook.

Leader

20 to 30 lb fluorocarbon, 18 to 24 in.

Common mistakes

• Setting the hook immediately on bait (give it a few seconds)
• Fishing too fast; drag it slowly along the bottom
• Losing the fish at the edge; net or slide it, do not lift

Landing

Do not lift a flounder by the line; slide it up on a wave.

Handling

• Sharp teeth

Use pliers; they can cut fingers or line.

Keep or release

Excellent eating (LSU). Texas closes flounder harvest November 1 to December 14 (TPWD Sea Rim sheet); see the regulations file.
