Whether termed exotics, transplants, or aliens, nonindigenous species are those that enter an ecosystem beyond their historic range. This book is based on an extensive and ongoing electronic database of over 500 nonindigenous fish taxa (species, hybrids, and unidentified forms) in U.S. inland open waters, and is comprised primarily of summary accounts of each taxa. Also, the book summarizes the historical trends and spatial patterns of fish introductions nationwide and gives an overview of the database itself, which is a major subset of a larger research database of other nonindigenous aquatic species.
