How to Know the Freshwater Fishes: Pictured-Keys for Identifying all of the Freshwater Fishes of the United States

How to Know the Freshwater Fishes, first published in 1957 as part of the "How to Know" Nature Series, provides keys, descriptions, and (for nearly all species) a line-drawing of all the freshwater fish found in the United States. Although some scientific names in this first edition of the book are now out-dated, the keys, illustrations and descriptions make this guide a valuable reference for those wanting to identify and learn more about North American fish.
