Permit off Sanibel and Captiva show up on nearshore wrecks, passes and reef structure rather than the shallow flats they’re famous for further south. In Southwest Florida’s Gulf waters, outside the Special Permit Zone that covers the Biscayne Bay area, FWC sets a minimum size of 11 inches fork length and a bag of 6 per harvester, open year round.
FWC splits permit regulations into two sets. A Special Permit Zone around Biscayne National Park carries its own tighter rules, and FWC points anglers to the park regulations for those. Sanibel and Captiva sit well outside that zone, in the Gulf, where FWC lists the rule for all other state waters as a minimum size of 11 inches fork length, a bag of 6 per harvester, and an open season year round. Hook and line, cast net and beach or haul seine are the allowed gear; multiple hooks with natural bait and snatching are prohibited.
Anyone reading a permit regulation meant for the Biscayne area and applying it to a Sanibel or Captiva trip will get both the size limit and the season wrong. Confirm which zone applies before keeping a fish.
Permit around here relate to structure with current, not open flats. Nearshore wrecks and rock piles off Sanibel and Captiva hold permit schooling over hard bottom, and passes moving water on a tide, Blind Pass between the two islands, Captiva Pass, and Redfish Pass further north, concentrate bait that draws permit in to feed.
Bridge pilings and channel markers with strong current running past them are also worth working, since permit often relate to any hard structure that breaks current and holds crustaceans.
Permit are a warm-water fish, and the Gulf-side population off Sanibel and Captiva is most active through the warmer months, spring into fall, when water temperatures stay consistently up. A strong moving tide over a wreck or through a pass produces better than slack water, the same principle that governs most structure-oriented Gulf fishing here.
Live crabs, small blue crabs in particular, are the standard permit bait and worth the effort to find or buy before a trip targeting them specifically. Fished on a fish-finder rig or free-lined near a wreck or pass, a live crab drifted naturally with the current is hard for a permit to refuse.
Shrimp and small live baitfish work as a secondary option when crabs aren’t available, though they generally produce less consistently than crab does for this species specifically.
Permit holding on a wreck or over a pass often feed with their heads down, tailing over the bottom the way a redfish does on a flat, which makes a bait presented right on the bottom near the structure more effective than one drifted higher in the water column. Anchoring or positioning slightly up-current of a wreck, then letting a live crab drift back naturally into the strike zone, mimics how a permit actually encounters food there.
Patience matters more with permit than with most inshore species. A school holding over a wreck may refuse several presentations before one angler’s bait gets eaten, and moving off a known holding spot too quickly after a slow start often means leaving fish that would have eventually committed.
Permit fight hard for their size and hold near structure that can cut you off fast, so tackle should lean toward the heavier end of inshore gear. A 7 foot medium-heavy spinning rod, 20 to 30 pound braid, and a 40 pound fluorocarbon leader gives enough strength to turn a fish away from a wreck or piling before it wraps you up.
Using Biscayne-area figures for a Sanibel or Captiva trip is the mistake that costs the most, since the size limit, bag and season all differ from the Gulf rule that actually applies here. Check which zone you’re fishing before assuming last year’s numbers or another region’s numbers still hold.
Light leader is the other common issue. Permit relate tightly to structure, and an undersized leader gets cut on a wreck or piling before the fight ever really starts.
A Florida saltwater fishing license is required to target permit off Sanibel or Captiva. See our Southwest Florida fishing license guide for what residents and visitors need, and the regulations page for the current figures across every species on this site. Our shore and pier fishing guide covers what’s realistically catchable without a boat around Sanibel, and the season and regulation calendar tracks Gulf-region rules for the species we cover most.
