Fish And Fisheries In Tropical Estuaries

Tropical estuaries are among the most modified and threatened of aquatic environments, supporting innumerable fisheries essential to the regions in which they occur. This book synthesizes the wealth of data available in this area, much of it being brought together by Stephen Blaber for the first time. It will provide readers with a comprehensive understanding of the fishes, the environments in which they live, and the management of biologically healthy estuaries and sustainable fisheries.

Das zweibändige Werk Fish and Fisheries in Estuaries: A Global Perspective enthält eine Darstellung des aktuellen Wissensstandes über Fische in Ästuaren. In Beiträgen von mehr als fünfzig international anerkannten Forschern und Experten für Ichthyologie in Ästuaren präsentiert dieses wegweisende Übersichtswerk die Themen Fischbestände und funktionelle Gruppen, Rekrutierung und Produktion in Ästuaren, Ernährungsökologie und trophische Dynamik, Erhaltung von Fischen in Ästuaren und viele mehr. In dreizehn ausführlichen Kapiteln werden die wichtigsten Aspekte zu Fischen und Fischerei in Ästuaren rund um die Welt beschrieben. Es wird die Biologie der Fische in Ästuargewässern und ihre Verbindung zu den dortigen Ökosystemen betrachtet, und es wird analysiert, wie sich die menschengemachte Industrialisierung und globale Ereignisse wie der Klimawandel auf einheimische und andere Arten auswirken. Weitere Themen sind die Vielfalt der Lebensräume, das Verhalten von Fischen bei der Nahrungssuche, Instrumente und Modelle der Umwelttechnik, Gefahren und Risiken für Fische und Fischerei in Ästuaren sowie die Gesundheit der Umwelt in Ästuaren. Dieses maßgebliche Referenzwerk enthält detaillierte Informationen über die Biologie und Ökologie von Fischen und Fischerei in Ästuaren und bietet außerdem: * Eine Betrachtung aktueller Ansätze und künftiger Forschungsrichtungen, die darauf abzielen, ein Gleichgewicht zwischen der Nutzung und der Erhaltung von Fischen in Ästuaren zu erreichen * Eine Erörterung der Umweltqualitätsziele sowie der nachhaltigen Fischerei und Bewirtschaftung der Ästuare * Eine Untersuchung, wie sich die zunehmende Nutzung von Ressourcen wie Nahrung, Raum und Wasser durch den Menschen auf die Fischerei in den Ästuaren auswirkt * Zahlreiche internationale Fallstudien zum Fischereimanagement, zu bedrohten Arten, zur Sanierung von Ästuaren, zur Fortpflanzung und Ontogenese und weiteren Themen * Eine Darstellung der Studien- und Probenahmeverfahren, der Feldausrüstung sowie der Verarbeitung, Analyse und Interpretation der Daten Das Werk Fish and Fisheries in Estuaries: A Global Perspective ist ein unverzichtbares Hilfsmittel und eine Referenzquelle für Fischbiologen, Fischereiwissenschaftler, Ökologen und Umweltwissenschaftler, Gewässerökologen, Naturschutzbiologen sowie Studierende der höheren Semester und Dozenten im Bereich Fischbiologie und Fischerei.

Research on the large array of tropical estuarine fishes has increased markedly in recent years and hence scientific knowledge about most aspects of these important fishes' biology and ecology is now catching up with that of their temperate equivalents. This landmark book draws together a vast wealth of information on tropical estuarine fishes and provides a vital reference point for all aspects of their study. The book's comprehensive contents include thorough coverage of the types and distribution of these fishes, their diversity and the environmental conditions and communities in which they live. Full details of their biology and ecology are an integral part of this book, as are details of these fishes' dependence on estuaries, man's interaction with the estuarine fish community and the conservation of estuarine species and the often threatened habitats upon which they depend. The author, Stephen Blaber, has a vast wealth of experience in the subject areas covered by this book and has produced a stimulating and extremely valuable volume that will be of huge importance for all those concerned with these fishes. He is based at CSIRO Marine Research, Cleveland, Queensland, Australia. Readership should include: fish biologists; fisheries scientists; aquatic scientists including those concerned with brackish, marine and freshwater environments; ecologists; environmental scientists and population biologists. Students studying for qualifications in fish biology and fisheries, particularly where there is a tropical element to their course will find this book of great value as a reference. Copies of the book should be available on the shelves of all libraries in research establishments and universities where biological sciences, fish biology, fisheries science or aquatic sciences are studied and taught.

The tropical estuarine systems of Mexico and Central America are an important part of the region ́s coastlines; for example Mexico alone possesses more than 770 thousand hectares of mangroves, as well as the largest estuarine mangrove complex on the American Pacific (Marismas Nacionales), yet is one of the poorest studied areas in the world. This is the first book that deals extensively with fisheries management issues in this region from physical-chemistry, ecological and socioeconomic views, providing an understanding on the function and the effects of human activities on these areas, with works undertaken by local scientist.

For the inhabitants of many of the world's major towns and cities, estuaries provide their first and nearest glimpse of a natural habitat. Despite the attempts of man to pollute or reclaim it, the estuarine ecosystem continues to provide a fascinating insight into a natural world where energy is transformed from sunlight into plant material, and then through the steps of a food chain is converted into a rich food supply for birds and fish. The book provides a concise readable introduction to estuarine ecology. First published in 1981, it soon established itself as the principle textbook of choice in the UK & NW Europe. This new edition builds upon the strengths of the earlier editions but has been thoroughly revised throughout. The new co-author brings a human impact dimension to the revised book. It is written for advanced undergraduate and graduate students (particularly taught masters) who have had a general ecology course, but no further training in estuarine science. It will be useful to both professional researchers and practical managers in marine ecology and environmental science who seek a compact but comprehensive introduction to estuarine ecology.

Many species of fish occupying inland waters reside in watershedsthat were or still are surrounded by forests and are dependent inmajor ways upon such cover. The interactions between fishes andforests are complex, multifaceted, dynamic processes involving mostinland surface waters, forests, subsurface waters, geology andsoils, climate and its changes, and the biotic components of therelevant ecosystems. These interactions also include the aspects offorestry tied to human development, economics, population growthand even philosophies. Fishes and Forestry is truly a landmark publication. Theeditors, Professors Northcote and Hartman, have drawn together andcarefully edited chapters written by 56 scientists from around theworld, covering a vast wealth of information never before appearingwithin the covers of one book. Following an introductory chapter,this exceptional work is broadly divided into sections covering:the ecology of forests, streams, lakes and estuaries; fish biologyand ecology; forestry activities and their effects on aquaticsystems and fishes; 14 chapters covering examples of fish-forestryinteractions from around the world and a final section coveringmeans of effecting better fish-forestry interactions. Fishes and Forestry is an essential purchase for allthose involved in inland fisheries, forestry and their interaction,including fisheries scientists, fish biologists, ecologists,environmental scientists and forestry scientists. Libraries in alluniversities and research establishments where these subjects arestudied and taught should have several copies on their shelves.

Interfaces between media, whether air-water or sediment-water interfaces or organisms themselves, pose considerable problems to marine organisms attempting to live at these boundaries. In the present volume, a number of authors address various aspects of these two topics. Locations under scrutiny range from intertidal areas to the deep sea, while both macro-and meiofaunal organisms are investigated. Distribution patterns and effects of variable temperatures, pressures, and salinities are analysed. Aspects of fouling induction and prevention are also addressed. This book is intended as a progress report from the 33rd European Marine Biology Symposium held in Wilhelmshaven, Germany, in September 1998.
