Alien species invade aquatic ecosystems through both intentional and accidental means. The voluntary introduction, if performed at all, is usually monitored by professionals who have made a risk assessment. Accidental incursion is more difficult to control and poses a potentially grave threat if left unchecked or undetected.
Nonindigenous Fresh Water Organisms focuses on this infringement in North American aquatic ecosystems. The 31 chapters measure the devastating ecological, and sometimes economic, impact caused by the encroachment of immigrant species. The book includes case studies such as the Zebra mussel, which arrived in the Laurentian Great Lakes via the ballast of a foreign ship.
There is a section for each pathway of introduction, which includes a chapter devoted to its North American history and an analysis of the potential harm caused by further intrusion. The final portion of the book is devoted to a prediction methodology for the success or failure of an introduction. The chapter on risk assessment is especially useful for the planning of a voluntary introduction.

CHOICE Review

There is increasing concern over introduction of nonnative organisms into surface waters. Thus, the subject is timely, and overall this book is an excellent overview of the problem, and well worth the purchase price. However, it was written by a panel of authors, so individual chapters vary a great deal in quality. Most chapters are very good (chapters 1, 13, 29, and 30, for example). But chapters 9, 15, and 21 do nothing more than review life history traits of nonnative molluscs. For a science book, there are too many errors in scientific fact. For example, life cycles of the trematodes Paragonimus westermani and Schistosoma mansoni are wrong. Likewise, the cestode Bothriocephalus is incorrectly placed in the Cestodaria. Annoying typographical errors should have been caught in proof. However, it is a must for any library maintaining holdings in zoology, aquatic ecology, limnology, fish, or fisheries.
