Fly fishing
Fly fishing is an angling method that uses a light-weight lure -- called an artificial fly -- to catch fish. The fly is cast using a fly rod, reel, and specialized weighted line. The light weight requires casting techniques significantly different from other forms of casting. The flies may resemble natural invertebrates, baitfish, or other food organisms.
Fly fishing can be done in fresh or salt water. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon, steelhead)
, such as wading flats for bonefish or redfish or surf fishing for striped bass and other assorted fish. Typically, most trout fly fisherman need to practice new skills to catch saltwater fish on a fly rod. Ocean fish are usually harder to catch. They can be extremely spooky, and much larger. Trout fisherman need to practice with at least an 8 weight fly rod and accurately cast the line 30–90 feet if they are going to have success—particularly in the flat areas fishing for bonefish, redfish, permit, tarpon
