One of the great misconceptions amongst fly fishing writers and indeed everyday fly anglers is that fish see the way humans see. Not only are fish eyes constructed different than human eyes, and for different intended purposes, but fish eyes are wired to fish brains differently. Further, how light acts in water is substantially different than the way it acts in air. There are also other key senses complexes through which fish perceive their food and environment in very different ways. One of these complexes, the Acoustico-Lateralis System, does not even exist in humans. At times these other senses may be even more important in fish feeding behaviors than sight.
As an aquatic biologist, environmental engineer, and avid fly angler Richard combines the above observations with the major environmental factors that affect the aquatic environments fish live in. From this he creates truly unique fly fishing perspectives and approaches not only for salmon, but for fly fishing in general.
