Fly fishing is a method of angling that uses a lightweight lure called a fly to catch fish. Unlike traditional fishing, where bait is used, fly fishing involves casting the fly with a specialized rod and line. The fly is designed to mimic the appearance and movement of insects or other small creatures that fish naturally eat. This technique is often practiced in freshwater environments, such as rivers and lakes, where species like trout and bass are commonly targeted. Fly fishing requires skill in casting and an understanding of fish behavior, making it both a challenging and rewarding outdoor activity.
