More than two decades since the first publication of his influential and highly sought-after Hatch Guide For New England Streams, author Thomas Ames Jr. has expanded the scope to include trout and salmon fisheries throughout the eastern United States. This new and updated volume titled The Pocket Guide to Eastern Hatches 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; and provides easy-to-follow pattern recipes, detailed descriptions, and illuminating photographs of both the natural insects and their artificial imitations.
