Permit (*Trachinotus falcatus*) are considered by many anglers to be one of the ultimate challenges in saltwater fly fishing. Powerful, intelligent and notoriously selective, they have earned a reputation for refusing even perfectly presented flies. Landing a permit is often regarded as one of fly fishing's greatest achievements.
Permit are found throughout many tropical saltwater destinations, including Belize, Mexico, Cuba, the Florida Keys and parts of the Caribbean. They inhabit shallow sand flats, coral edges, turtle grass and lagoons, often moving with the tide as they search for food.
Unlike bonefish, which feed primarily on shrimp and worms, permit specialise in feeding on crabs. Blue crabs, swimming crabs and other crustaceans form the majority of their diet, although they will also take shrimp and other marine invertebrates. Understanding exactly what permit are feeding on is one of the keys to success.
Most permit are targeted by sight. Anglers carefully search the flats for cruising fish, tailing fish or the distinctive shape of a permit moving across shallow water. They are often encountered individually or in small groups and can disappear as quickly as they appear, making concentration essential throughout the day.
Presentation is everything. Permit possess exceptional eyesight and can be extremely suspicious of unnatural movement. The fly should normally land well ahead of the fish before being allowed to sink naturally onto the seabed. Small, subtle strips are then used to imitate a crab attempting to escape. Retrieving too quickly or landing the fly too close will often cause the fish to spook immediately.
Crab patterns dominate permit fly boxes. Well-balanced flies that land softly, sink correctly and fish hook point upwards are the standard choice. As with bonefish, selecting the correct fly weight for the depth of water is often more important than the exact pattern itself.
An 8-weight or 9-weight fly rod is suitable for most permit fishing, although 10-weight outfits are often preferred where larger fish or stronger winds are expected. Tropical floating fly lines are almost universally used, paired with strong fluorocarbon leaders capable of coping with powerful fish around coral and other structure. Saltwater reels require smooth, reliable drags and sufficient backing to cope with long, fast runs.
At Peaks Fly Fishing, we believe permit tackle should be selected with accuracy in mind. The ability to place a crab fly precisely, often at relatively short notice and in windy conditions, is far more important than maximum casting distance. A balanced rod and tropical fly line make accurate presentations easier and reduce fatigue during long days on the flats.
Hooking a permit is only half the battle. Their first run is exceptionally powerful, and they are famous for making repeated long runs while using shallow water, coral and changing direction to their advantage. Even experienced saltwater anglers are often surprised by their strength.
Permit are often described as the fish that teaches humility. It is perfectly normal to spend several days seeing fish, making good presentations and still not land one. Patience, persistence and confidence are all part of successful permit fishing, and every encounter provides valuable experience.
For many travelling fly anglers, permit represent the pinnacle of flats fishing. They demand careful observation, accurate casting, thoughtful presentation and a balanced outfit that performs exactly when needed. Landing just one is enough to keep many anglers dreaming of their next tropical adventure for years to come.
