This classic saltwater fly is probably the most popular saltwater pattern in the world. The Black Clouser Deep Minnow is effective on nearly every predatory saltwater species. It is especially useful for stripers, bluefish, bonefish, redfish, snook, seatrout, and many others. It has also become a very popular freshwater streamer pattern. Every fly fisher should carry an array of sizes and colors of Clouser Minnows to be ready for anything.
