Profiling Permit Fish From Flats to Wrecks

Permit fish (Trachinotus falcatus) are deep-bodied, silver jacks of the western Atlantic, known for long, dark, sickle-shaped dorsal and anal fins, blackish pectoral fins, and a patch of orange-yellow on the belly in front of the anal fin. The species reaches about 48 inches in fork length, with a maximum published weight around 79 pounds, though most fish anglers see are smaller. The IGFA all-tackle world record is 60 pounds, caught off Ilha do Mel, Brazil.

Permit range from Massachusetts to southeastern Brazil, including the Bahamas and much of the West Indies, and they are a signature fish of South Florida and the Keys. Adults use channels and holes, sandy flats, reefs, and at times mud bottom, from the shallows out to about 120 feet. They eat crabs, shrimp, mollusks, and small fish, and they are famously hard to fool.

This unique fish can grow to a maximum size of around 50 inches in length and up to 35 pounds in weight. The largest permit fish are typically caught in the Caribbean and the Gulf of Mexico. The fish is a highly sought after gamefish due to its size, strength and impressive fighting ability. It is commonly found in shallow waters, around coral reefs and mangroves, and in estuaries and lagoons. It feeds on small crustaceans, mollusks and small fish.

How Do You Catch Giant Permit on Light Tackle?

In our course on fishing for giant permit in Florida, Capt. Scott Fawcett covers tackle that balances a delicate presentation with the power to stop a big fish, sight casting to moving schools, bait selection for wary fish, reading water conditions to see and hook permit on the flats, and fighting fish near coral and rock. View the short trailer below.

What Are the Best Techniques for Permit Fishing?

Permit are strong, fast fish that make long, hard runs, and on light tackle a big one can take a long time to land. How you fish for them depends on where they are.

Sight fishing the flats is the classic approach. Permit push onto shallow sand and grass flats to feed, often tailing as they root along the bottom for crabs. Spinning gear with a live crab, cast ahead of the fish so it lands without spooking it, is the most dependable way to get a bite in shallow water.

Fly fishing for permit is one of the hardest challenges in saltwater angling. Crab patterns are the standard, presented to tailing or cruising fish on the flats. Expect refusals. Permit inspect a fly closely and turn away from anything that looks or moves wrong.

Fishing reefs and wrecks puts you on permit in deeper water, especially when they gather to spawn. Live crabs and jigs fished around the structure are the usual approach. Sharks follow these aggregations closely, so the fight needs to be short.

What Family Does the Permit Fish Belong To?

Permit are members of the jack family, Carangidae, in the genus Trachinotus, the same genus as the Florida pompano. Like other jacks, they are built for power and speed, with a deep, compressed body and a strongly forked tail.

Smaller permit tolerate brackish water, and in summer, juveniles form large schools in the surf zone along sandy beaches. Adults are usually found alone or in small schools on the flats, but they gather in much larger numbers to spawn.

When and Where Do Permit Fish Migrate?

The best-documented movement is the spawning gathering. In the Florida Keys, permit aggregate on natural and artificial reefs around the full moons from March through June, according to research led by Florida International University and supported by Bonefish & Tarpon Trust. Survey counts have ranged from a single fish to several hundred at the sites studied, and sharks, including bull, Caribbean reef, and great hammerhead sharks, have been seen at most of them. Permit spawn offshore, away from the flats where most anglers find them the rest of the year.

Those spawning months are the reason for Florida's seasonal protection. In the Special Permit Zone, which covers Biscayne Bay and the Florida Keys, permit harvest is closed April 1 through July 31.

Beyond spawning, permit shift between the flats, channels, and deeper reefs with water temperature, tide, and food. Movement patterns vary from place to place, so local knowledge of a given fishery matters more than any general rule.

How Do Permit Fish Hunt and Feed?

Permit are bottom feeders. On the flats they cruise and root along the bottom for crabs, shrimp, and clams, often tipping down to feed with their tails breaking the surface, the "tailing" fish that flats anglers look for. On reefs and wrecks they feed around the structure on the same kinds of prey, along with small fish.

They are also wary. Permit have sharp eyesight and spook at a boat's shadow, a line slapping the water, or a bait that lands too close. Most flats permit are lost before the cast ever happens, to noise, a bad approach, or a crab dropped on their heads.

What Artificial Lures Work Best for Permit?

Lures for permit imitate what permit eat, which mostly means crabs and shrimp. Crab imitations and small jigs are the standard, fished slowly along the bottom so they look like prey trying to hide.

Natural colors, such as tan, olive, and brown, match the bottom and the forage on the flats. Size the lure to the crabs and shrimp the fish are eating where you are fishing. On reefs and wrecks, jigs heavy enough to reach the fish in current are the usual choice.

What's the Best Live and Dead Bait for Permit?

Live crabs are the top permit bait, with shrimp a close second. Crabs about the size of a silver dollar to the palm of your hand match what permit eat on the flats, and a lively crab that swims down toward the bottom draws strikes that a dead one may not.

Fresh dead crab and shrimp can still catch permit when presented on the bottom where the fish are feeding, but live bait is the better bet on wary fish.

One rule to know: Florida prohibits harvesting permit with multiple hooks used with live or dead natural bait, so rig natural baits on a single hook.

What Size Hooks Should You Use for Permit Fishing?

Match the hook to the crab or shrimp. Small, strong hooks in roughly the 1/0 to 4/0 range cover most permit baits, sized so the bait can still swim and the point stays exposed. Circle hooks reduce gut-hooking, which matters on a fish that is often released, and a circle hook lets a permit take the bait and turn before you come tight.

Whatever hook you choose, use a single hook, keep it sharp, and use a strong enough hook to hold a big fish through a long fight on light tackle.

Permit Fishing Regulations in Florida

FWC manages permit differently inside and outside the Special Permit Zone. The zone covers state and adjacent federal waters south of Cape Florida on the Atlantic side, Biscayne Bay south of the Rickenbacker Causeway, and federal waters south of 25°09' N near Cape Sable on the Gulf of Mexico side. In practice, that means Biscayne Bay and the Florida Keys.

Inside the Special Permit Zone, the minimum size is 22 inches fork length, with 1 fish per person and no more than 2 per vessel, and harvest is closed April 1 through July 31. Outside the zone, there is a slot of 11 to 22 inches fork length with a 2-fish daily bag, and one fish over 22 inches may be kept as part of that bag, with no more than 2 fish over 22 inches per vessel. Harvest with multiple hooks and natural bait, and snatching, are prohibited everywhere. Gear is limited to hook and line in state waters, with spearing also allowed in federal waters, and Biscayne National Park has its own rules.

One closure every Keys permit angler needs to know: since 2021, FWC has closed Western Dry Rocks, a one-square-mile area about 10 miles southwest of Key West that protects a multi-species spawning aggregation site, to all fishing and possession of fish from April 1 through July 31. Boats may pass through only with fish stowed and gear secured.

These rules change, so check FWC's permit regulations for the current limits and the exact zone boundaries before you fish. Many permit anglers release every fish, and a quick release with the fish kept in the water gives it the best chance, especially when sharks are around.

Put Your Permit Knowledge into Action

Permit reward the angler who understands them: where they feed, what they eat, how they react to a boat and a bait, and when they gather to spawn. On the flats that means a quiet approach, a crab placed ahead of a tailing fish, and the patience to wait for the right shot. On reefs and wrecks it means fishing the structure and keeping fights short when the sharks show up.

To see it done, watch Capt. Scott Fawcett work giant permit on the South Florida flats in our permit fishing course.
