The global scale of alien species invasions is becoming more and more evident in the beginning ofthe new millennium. Though the problem ofbiological invasions became a rapidly growing research area, there are large gaps still, both geographically and the matically, to be filled in the near future. This book is the first attempt to provide an overall picture of aquatic species invasions in Europe. Its geographical scope stretches from Irish waters in the west to Volga River and the Caspian Sea in the east, and from Mediterranean in the south up to the Arctic coast of Europe. Not all parts of the continent could be equally covered, as in some countries species invasions are not studied yet. The book tends to represent the array of all major European aquatic systems on the broadest geographical and ecological scope possible from fully saline seas, semi-enclosed brackish water bodies and coastallagoons to freshwater lakes, major river systems and waterways. The key objectives include the present status and impacts caused by non-native aquatic species in European waters. Please note that lengthy species lists submitted for publication and additional informa tion were put on the Internet, as the electronical version of these tables benefits from computer assisted search for data (http://www. ku. lt/nemo/EuroAquaInvaders. htm). Altogether more than 100 scientists from 24 countries have joined to synthesize the available information on bioinvasions. However, the book does not claim to be fully comprehensive.

The use of alien species is a proven means to increase production and value from aquatic ecosystems. In the Mekong/Lanchang basin, alien species such as tilapia (Orechromis spp.) play an important role in providing cheap and readily available protein to rural and poor sectors. However, alien species are now recognized as one of the most significant threats to aquatic biodiversity. Several steps are necessary for effective use and control of alien species, but one of the most important was identified to be following codes of practice similar to that developed by the International Council for the Exploration of the Sea.

Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.

There are over 1300 species of cyprinids in Asia, and these are utilized by people for food (capture fisheries and aquaculture) and as ornamental species. This publication focuses on cyprinid species that are bred in hatcheries and used in aquaculture and restocking activities. Introduced and threatened species of cyprinids in Asia are also discussed. We are well aware that we have not covered many other cyprinid species that are utilized by people in Asia in various ways: wild species in capture fisheries, self-recruiting species in aquaculture ponds and other water bodies, and aquarist species.

Non-indigenous species (NIS) are common in the United States landscape. While some are beneficial, others are harmful and can cause significant economic, environmental, and health damage. This study, requested by the U.S. House Merchant Marine and Fisheries Committee, examined State and Federal policies related to these harmful NIS. The report is presented in 10 chapters. Chapter 1 identifies the issues and options related to the topic and a summary of the findings from the individual chapters that follow. Chapters 2 "The Consequences of NIS" and 3 "The Changing Numbers, Causes, and Rates of Introductions" examine basic aspects of NIS, their effects, how many there are, and how they get here. Technologies to deal with harmful NIS, including decision-making methods and techniques for preventing and managing problem species, are covered in chapters 4 "The Application of Decisionmaking Methods" and 5 "Technologies for Preventing and Managing Problems." Chapters 6, "A Primer on Federal Policy," 7 "State and Local Approaches from a National Perspective," and 8 "Two Case Studies: Non-Indigenous Species in Hawaii and Florida" assess what various institutions at the Federal, State, and local levels do, or fail to do, about NIS. Chapters 9 and 10 place NIS in a broader context by examining their relationships to genetically engineered organisms, to international law to other prominent environmental issues, and to choices regarding the future of the nation's biological resources. Appendixes include: lists of boxes, figures, and tables in the document; list of authors, workshop participants, reviewers, and survey respondents for the study; and list of references by chapter. Additional sections contain an index to common and scientific names of species, and a general index. (MDH)
