Nymph fishing is an extremely effective way to fish. These flies are fished below the water surface traditionally as a dropper below a dry fly or independently fished under a strike indicator. In order to get these flies down to the fish the aid of a weight or split shot can help. These patterns resemble aquatic insects that make up 90% of trout's food source. Nymph fishing is not only effective on with trout but is also commonly used for bass, crappie, sunfish, bluegill, steelhead and more. They are also effectively fished in rivers, lakes, streams or anywhere fish swim.
