Permit are regular visitors to the saltwater flats at La Salinas and Rio Negro, where they like to hunt for food in shallower water around two-and-a-half to five feet deep. It is in this environment that they become an important target for fly fishermen seeking to catch what is arguably the world's most difficult fish to catch on a fly. The 'grand slam (bonefish, tarpon and permit caught in the same day on fly)' is the dream of all serious fly fishermen and because permit are quite common in Cuba, it does offer visitors a realistic chance of achieving their dream. Permit are tough to catch on a fly, usually a crab imitation but surprisingly easy to catch on real crab baits. Once hooked, they are a powerful fish that race around the flats, rubbing their jaw across the bottom in a bid to shed the hook. A real tough cookie in every sense of the word, they represent the cream of Cuban flats fishing.
