Fegely reports--with an eye to sports fishermen but a general reference approach for whomever--on the behavior, size and distribution, and individual features of about 60 North American freshwater fish, grouped not according to family but by ""ecological or behavioral characteristics""; thus we have chapters on ancient fish, endangered fish, panfish, game fish (defined as ""any of our larger fish that are sporty enough to put up a battle on the end of the line""), and others. General comments on how fish breathe, swim, ""hear,"" mate, etc., precede the listing-which is compact, conveniently labeled, and as up-to-date as the snail darter's recent victory over the dam builders.
