The Crystal Schminnow is an effective fly for any species that's looking for a shrimp or minnow because it approximates everything without specifically imitating anything. Saltwater species like snook, seatrout, baby tarpon, bluefish, mackerel, redfish, and even false albacore or tuna willingly eat this fly. Freshwater predators like largemouth bass, peacock bass, shad, crappie, and others will take it with little reservation as well.
The Clouser has likely caught more species than any other fly, from bluewater species to bluegill. It can easily be adapted to your needs by modifying the size, sink rate, material and color in any way you want.
The Boehm's Gurgler has proven to be a winner for surface-feeding baby tarpon, but it can be equally effective when used for snook, seatrout, redfish, jacks, and highly aggressive bluefish. Freshwater species like largemouth and peacock bass can't resist a well presented gurgler.
The Fleeing Crab is a great pattern to use for crab eating fish of all types including redfish, permit, bonefish, and black drum. Pompano on the flats are a possibility as they scour the bottom in search of crabs or even sand fleas.
The Seaducer is a simple yet versatile and productive fly pattern that will catch a wide variety of species in both fresh and salt. Snook, tarpon, redfish, seatrout, sharks, largemouth and peacock bass and many others will investigate and eat this fly.
