Naturalized Fishes of the World - Tapa blanda

Fish are an important part of a region's biological diversity and a human resource throughout the world. They are valuable for food and/or as a sporting asset. The human interest in fish has inevitably led to the widespread practice of introducing various species to waters outside their normal range. This unique book describes when, where, why, how, and by whom the alien inland fishes now living in a wild state throughout the world were introduced. It also exploreshow they subsequently became naturalized and what, if any, effects they have had in their new environment.

Christopher Lever has had a lifelong interest in natural history, and first began to specialize in the study of naturalized animals nearly 40 years ago. He has written books and numerous articles and papers, as well as broadcasting on radio and television. An ardent conservationist, he is chairman, council member or trustee of many nature conservation organizations and, appropriately, is a member of the World Conservation Union (IUCN) Species Survival Commission's Re-introduction Specialist Group.
