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.

Estuaries of South Africa presents an authoritative and comprehensive review of the current status of that country's estuarine research and management. Contributors provide information on a wide range of topics, including geological, physical and chemical processes; diversity and productivity of plant and animal communities; interactions among estuarine organisms; and system properties, ecological modeling and current management issues. This broad scope is complemented by a comparative perspective, resulting in a volume that provides a unique contribution to the subject of estuarine ecology. This volume is relevant to all those working in this field throughout the world.

This book examines the economic costs and benefits of the ecological restoration of estuaries, utilizing case studies from South Africa. Estuaries are important ecosystems from both an ecological and human perspective. Yet, in many parts of the world they are often degraded environments, facing threats from climate change, invasive species, fire and wastewater pollution. While the environmental benefits of restoring degraded environments are well discussed, this book specifically examines the economic benefits of doing so. It applies a cost-benefit analysis, which focuses on a range of key ecosystem services, including human health, fishing value, recreational value and property value. The book utlizes three detailed studies of the Swartkops estuary, the Great Brak estuary and the Knysna estuary in South Africa, but also draws out lessons that can be applied to coastal environments across the world. Overall, this book demonstrates that ecological restoration does pay and that the value of additional ecosystem services gained through restoration far exceeds the costs associated with this restoration process. This book will be of great interest to students and scholars of environmental management and restoration, ecological economics, ecosystem services and environmental conservation.

This book provides recent environmental, ecological and hydrodynamic information for the major estuaries and the coastal marine systems of the Western Indian Ocean Region. It covers various functions and values of the region’s estuarine ecosystems and their respective habitats, including the land/ocean interactions that define and impact ecosystem services. The Western Indian Ocean region covered by this volume consists of the continental coastal states of Kenya, Mozambique, South Africa and Tanzania and the island states of Madagascar, Mauritius, Seychelles and Comoros.

Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
