More than two decades since the first publication of his influential and highly sought-after guide to matching New England insect hatches, Thomas Ames Jr. has expanded its scope to include trout and salmon fisheries throughout the eastern United States. This updated volume examines how hatch-matching patterns and techniques have evolved in the 21st Century to meet the changing and challenging conditions of our Eastern rivers and streams. The Pocket Guide to Eastern Hatches provides easy-to follow pattern recipes, detailed descriptions, and illuminating photographs of both the natural insects and their artificial imitations.
