Book excerpt: This no-nonsense guide was written by a professional trout fisheries biologist. It is a convenient size for keeping in your fly vest. Brian Chan explains the seasons of lakes, their anatomy, entomology/food source profiles, lake fishing strategies, pattern selection, knots, releasing fish. Includes color insect and fly plates and many illustrations (knots, insect emergence dates, insects, lake diagrams, etc). We are introducing this book to the United States. It has been extremely popular in British Columbia and should be equally so in the United States.
