Ken Schultz's : Guide_to_Saltwater

These books are primarily intended for the angler, placing major emphasis on gamefish species (nearly 260) sought in the fresh- and saltwaters of
Canada, the United States, and Mexico, and on the prey species that most
gamefish use for forage. Although many hundreds of species are included
here, such compact books lack room for detailed information about many of
the lesser species; however, they are well represented in the information that
exists under certain groupings. For example, there are more than 300
species of “minnows” in North America, and much of what is said about
them as a group in the freshwater guide pertains to the majority of individuals. Profiles are provided, nonetheless, of some of the more prominent
members of this group.
The same is true for some larger, more well-known groups of fish, like
sharks. There are at least 370 species of sharks worldwide and dozens in
North America. The saltwater guide provides an overview of this group, as
well as specific information about the most prominent North American
members. And, of course, color illustrations help identify the individual
species profiled.
