March 2025 — Naples / Marco Island: Cobia following rays through Pine Island Sound. March is a early spring month with water in the 62–70°F range — cobia migration in full effect; inshore species moving from winter holes to flats. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics for this month.
What’s Biting — March 2025
Primary targets this month: Cobia, Snook, Redfish.
Cobia
Peak cobia migration. Sight-fishing along the beach, around Gordon Pass, Capri Pass, nearshore reefs (5MR, ARC), and stone crab buoys in 30–60 feet, and following stingrays in clear water is the move. You need calm seas (1–2 ft) and sun overhead to spot fish. Run the beach 1/4 to 1/2 mile off the sand looking for dark torpedoes — single fish, pairs, or pods of 4–6. Cast 4–6″ bucktails (chartreuse, white, pink), large soft plastic eels, or live eels and pinfish. Cobia will often follow the boat after first refusal, so make a second cast.
Snook
Snook are in the mangrove shorelines of the Ten Thousand Islands, Marco River, Rookery Bay, Naples Bay docks, Gordon Pass jetties, and Doctor’s Pass. Live pilchards, scaled sardines, and finger mullet are top live baits. Artificial: white DOA Bait Buster, MirrOdine, and walking topwaters at first and last light. Always check current FWC snook season dates — slot is 28–33″ Atlantic, 28–33″ Gulf, with seasonal closures.
Redfish
Redfish are in the back bays of the Ten Thousand Islands, Rookery Bay, Coon Key, Goodland flats, and the shorelines south of Marco Island. Cut bait, gold spoons, and soft plastics on light jigheads all produce. Match the tide and look for activity on shorelines with clean water.
Water Conditions & Patterns
Water temperatures are running 62–70°F. Cobia migration in full effect; inshore species moving from winter holes to flats. Ten Thousand Islands fishing is heavily tide-driven — the backcountry rivers fish best on the first two hours of outgoing tide as bait flushes out. Beach tarpon are typically most active two hours either side of high tide.
Check the NOAA marine forecast and tide charts before launching. Wind direction matters more than wind speed for inshore fishing — east winds tend to push clean water in, while strong westerlies can muddy the bays.
Tactics & Tackle for This Month
- Cobia readiness. Keep a heavy spinning rod (8000-class reel, 40–50 lb braid, 60–80 lb fluoro leader) 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 (amber or copper for clarity) are essential.
- Bait migration. Spanish, kings, and predators follow bait pods — keep an eye on diving birds and surface activity.
March Outlook
Cobia migration intensifies through the month and peaks in April. Inshore species (snook, redfish, seatrout) shift from winter holes onto warming flats.
Regulations Reminder
Snook: 28–33″ slot (Atlantic), 28–33″ slot (Gulf), one fish per angler per day; seasonal closures apply (typically Dec 15–Jan 31 and Jun 1–Aug 31 on Gulf; Dec 15–Jan 31 and Jun 1–Aug 31 on Atlantic — verify current FWC dates). Snook stamp required. Redfish: 18–27″ slot, one per angler per day (verify current FWC zone-specific rules). Cobia: 36″ fork length, one per harvester, two per vessel in state waters (Florida — verify current rules). Always verify the current FWC regulations at myfwc.com before your trip — sizes, bag limits, and season dates change.
