March 2025 — Louisiana: Cobia appear at nearshore rigs, spring redfish building. March is a early spring month with water in the 62-70°F range — COBIA peak migration; trout and redfish transitioning to flats. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics.
What’s Biting — March 2025
Primary targets this month: Redfish, Speckled Trout, Sheepshead, Black Drum.
Redfish
Redfish in the Delacroix marsh, the Hopedale marsh, the Venice area (Pass-a-Loutre, Tiger Pass), Calcasieu Lake (sight-fishing trophy reds), and the Empire/Buras area — Louisiana is the world’s premier redfish fishery. Cut bait, gold spoons, and soft plastics on light jigheads.
Speckled Trout
Trout holding in Calcasieu Lake (Big Lake), Lake Pontchartrain, the Delacroix marsh, Vermilion Bay, and Cocodrie — gator trout fishery (5+ lb fish common in Big Lake). Live shrimp under a popping cork, soft plastic jigs in natural colors (root beer, new penny, opening night).
Sheepshead
Sheepshead are stacked for the winter/early-spring spawn. Target the offshore platforms, the passes, the marsh dock pilings, and the inshore wrecks. Fresh fiddler crabs and live shrimp on a #1 or #1/0 octopus hook with minimal weight. Bites are subtle — set on the slightest tap. Vertical jigging tight to structure produces best.
Black Drum
Black drum (bull drum 30+ lb) on the marshes, the bayou edges, and the passes — schoolies in the marsh and bulls in the deeper passes. Cut blue crab, fresh shrimp, or peeler crab on a 5/0-7/0 circle hook with enough weight to hold bottom. Slow, deliberate fishery — set the rod and wait for the rod to bend.
Water Conditions & Patterns
Water temperatures are running 62-70°F. Cobia peak migration; trout and redfish transitioning to flats. Louisiana’s marshes are heavily wind-driven; tide range is minimal but moving water still concentrates fish at marsh creek mouths and pass openings. Falling water on a falling tide is the prime redfish window. Offshore rigs fish all tides — current direction matters more than tide.
Check the NOAA marine forecast and tide charts before launching. Wind direction often matters more than wind speed for inshore fishing — clean water beats churned water nine times out of ten.
Tactics & Tackle for This Month
- Cobia readiness. Keep a heavy spinning rod (8000-class, 40-50 lb braid, 60-80 lb fluoro) ready with a bucktail or live eel — cobia don’t announce themselves.
- Sight-fishing weather. Plan trips around calm seas and sun overhead. Polarized lenses essential.
- Bait migration. Spanish, kings, and predators follow bait pods — watch for diving birds and surface activity.
March Outlook
Spring transitions accelerate — water warming, fish moving onto flats, migrations intensifying.
Regulations Reminder
Redfish: 18-27″ slot, one per angler per day (verify FWC zone-specific rules). Seatrout/Speckled Trout: FL: 15-19″ slot, 3 per day (verify zone). TX: 15-25″ slot, 3 per day. LA: 12″ minimum, 15 per day (verify current). Sheepshead: 12″ minimum, 8 per day (FL). Black Drum: 14-24″ slot or 16″ minimum depending on state; 1-5 per day. Always verify current state regulations before each trip — slots, bag limits, and seasons change.
