The nymph is one of troutfishing's most important flies. Mastery of the nymph requires not just selecting a fly that looks a little like the trout's food, but also adopting the correct retrieve. To deceive a stillwater trout which has settled into a natural feeding pattern, good presentation is essential. In this book, Gordon Fraser, who gave his name to the Fraser nymphs, explains how this can be achieved. Illustrated with photographs, line drawings and a colour section covering nearly 30 nymphs, Mastering the Nymph is a guide for the serious troutfisher.
