I read it 10 yrs ago and was impressed. Most or all recreational fisherman want to improve upon their productivity. A novice fisherman can learn where, when, how, and with what (s)he should do to improve productivity. For example: What do gamefish see? What is color to a fish? What causes fish to pursue your offering?
An excellent science based textbook although some information is a little dated given it's 30 years old. A good foundation for any fisherman. It's freshwater focused, but contains information that could also apply to saltwater fishing.
