The primary purpose of this guide is to simplify the identification of flatfish found along the Pacific coast of North America. It is intended for those who do not have the experience or the time to use a scientific key for identification. The guide is useful for commercial fishermen, fish processors, and fisheries managers. Recreational fishermen can use the photographs and illustrations to identify the species they see. Divers who don't collect fish for later identification will also find the book helpful. Printed on water-resistant paper to withstand hard use and wet conditions.
