"If, as a fly fisherman, you wish to understand your quarry and its instinct with more insight you must understand fish vision, for this is the primary sense fish use to hunt their prey. Such knowledge will allow the fisherman greater understanding of how the the fish sees its world and consequently how he should modify his fishing tactics. This book will give the fly fisher a greater insight into the visual environment of the trout by presenting facts and theories not found in other publications on this subject. Although the text is based on scientific aspects of fish vision it is written with the intention of making the subject readily understood by the layman. The book is comprehensively illustrated with coloured diagrams aimed at making the text more easily digested. After reading this book any fly fisherman should be able to fish with a new understanding of his quarry and so increase his chances of the delights of more tight lines!"
