Southern Flounder

Season in Louisiana

LSU: mature flounder stage in the lower estuary in fall and migrate to the Gulf mid-October to mid-November; very few large fish inshore until February or March. Winter flounder at drain mouths and rocks (Felsher). (Our inference)

Season by region

Where to find them

Drain mouths on a falling tide and around rocks in winter (Felsher); lower estuary before the fall migration (LSU).

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). See Louisiana rules.
