Fly fishing is both an art and a science. Laying out a perfect cast in exactly the right place, and tying a fly that is the perfect imitation of the real one are examples of the art side. Knowing where the fish are and what fly to use is part of the science side. Here are some tips on using the right fly.
One of the simplest ways of determining what fly to use is to look along the banks of the river. The bugs that live along the bank will eventually fall in the river and be eaten. When looking for bugs look on the ground, in the bushes, and in the trees.
Fish are sensitive to shape, color and size, so using a fly that is an exact imitation of the real bug is important. Having a wide selection of flies in your box is the key to success. Some people even bring their vice and fly tying materials with them. Then after observing what bugs are around, they tie a few to mimic what they have found. It is important to start with the right fish hook size to insure the bug is the correct size.
Fish will eat beetles, ants, grasshoppers, and almost any little thing that crawls, hops or flies. They also eat aquatic bugs. To figure out what aquatic bugs the fish are eating you will need a fine seine and seine the river in a few places. By seining the river, you find all the bugs living there and the shells of the bugs that have hatched. Armed with this information, you’re ready to go to your fly box for your vice.
Another good way to learn exactly how to seine and what you are looking for is to watch a fishing video on the subject. A good video is a fast way to learn. There are even some online fishing games that may help you learn.
