Marsh Mayhem, Surf Slingers, and Last Chance Snapper - Your South Louisiana Fishing Rundown

Artificial Lure here, giving y’all the September 17th fishing rundown for the inshore and nearshore Gulf out of south Louisiana—your boots-on-the-bow report for marsh, bay, and a touch of blue. Sun got up around 6:48 this morning and will duck behind the cane about 7:03 tonight. Skies are mostly clear with a muggy high near the mid-80s, and light southeast winds picking up through the day—that’ll keep the skeeters honest but shouldn't put a damper on the bite. Expect a bit of haze, as humidity’s true to form. Heavy dew at sunrise, so your deck shoes might get slick but that’s just par for the marsh. Tides are perfect for serious action today. According to Tides4Fishing, the tidal coefficient is at 59—a healthy average that puts some water on the move without making the marsh a washing machine. There’s a decent mid-morning incoming, meaning bait’s pushing into interior ponds and the current’s sweeping around all those points in the bayous. With the moon setting right after dawn and a nice evening rise, peak fish feeding should overlap perfectly with daybreak and late afternoon. September’s the heart of the transition. Inshore, redfish are rampaging—just last week, Nicole Chavers wrangled a 42-inch bull red on half a crab near Lafitte, proving the big ones are prowling the passes and edges of Barataria and Timbalier Bay. Live or cut crab, big shrimp, or mullet chunks are top natural baits for bulls right now. If you’re like me and love tossing hardware, paddle-tail plastics—especially in shad and chartreuse under a Pro-Cure slather—are deadly around grass lines and oyster mounds. Gold spoons are always money on a bright day, especially near Fourchon and the edges of Grand Isle’s surf. Speckled trout are in transition: some nice slabs came from Elmer’s Island and the Ship Shoal rigs, as Maurice Terrebonne showed off a beauty caught on live pogies under a Carolina rig. Early fall calls for mixing it up: topwater plugs at dawn (bone or chrome), then switch to shrimp-tipped Vudu or Matrix Shad under popping corks as the sun climbs. If you find birds working over shrimp or pogie slicks anywhere outside Bayou Dularge or Lake Pelto, stop and make a few casts—September birds are a dead giveaway for trout, as written up recently by Louisiana Sportsman. Out at the last gasp of snapper season, those heading out of Venice and Fourchon have been getting red snapper and mangrove snapper right up to the wire, with the feds closing red snapper September 15, according to RodnReelGirls. Mangroves are piling up on nearshore rigs and reefs—try cut pogie or squid for quick limits. Best bets today: - Fourchon surf and Queen Bess Island breaks for reds on gold spoons and cut crab. - Isle Dernières chain and the mouth of Terrebonne Bay for trout—topwater at sunrise, Matrix Shad or live croakers under corks when the sun’s high. - Venice east passes for late-migrating bulls and the last shot at snapper close-in.
