This report signals a new approach to ocean monitoring and management that lays a solid base using the principles of ecology and sustainable development while transcending traditional geopolitical and disciplinary divisions. LMEs are relatively large regions, often including the territorial waters of more than one nation, thus making coordination of monitoring and management highly desirable.

In this volume marine experts from countries of East Africa and southern Asia describe the conditions of marine resources of the large marine ecosystems of the Indian Ocean. Countries of the region represent over a quarter of the world's population, most of whom are existing at or below the poverty level. The potentials for economic growth through the development of coastal tourism, mariculture, fisheries, mineral extraction, and oil and gas production are examined by the authors in relation to the need for ensuring the long-term sustainability of marine resources. Case studies of resource assessments presented by several authors illustrate the magnitude of risk from continuing degradation of resources under the prevailing unmanaged conditions extending over much of coastal areas of East Africa and southern Asia. The authors explore the application of multidisciplinary ecosystem-based assessment and management strategies to the future economic development of the large marine ecosystems of the region. With the initiation of science-based management practcies, the ecosystems of the area can provide an important source of economic growth, improved food security, and nutritional benefits to the populations of stakeholders in coastal areas bordering the Indian Ocean

The character and materials of sedimentation in estuaries and lagoons along the 570 km Natal Coast are described and analyzed. Sites examined include the Greater St. Lucia lagoon system with its 9 major contributing rivers, Richards Bay with its 2 main contributing rivers, and 28 rivers that discharge directly into the Indian Ocean without passing through an intermediate lagoonal filtering system other than their own estuaries. Discussion is based on field and remote sensing investigations and borehole data, and is supported by pertinent maps and cross-sections. The nature and processes of sedimentation along the Natal coast are representative of events along more than 2000 km of African coast from central Mozambique to eastern Cape Province.

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.

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.

St Lucia is the world's oldest protected estuary and Africa's largest estuarine system. It is also the centerpiece of South Africa's first UNESCO World Heritage Site, the iSimangaliso Wetland Park, and has been a Ramsar Wetland of International Importance since 1986. Knowledge of its biodiversity, geological origins, hydrology, hydrodynamics and the long history of management is unique in the world. However, the impact of global change has culminated in unprecedented challenges for the conservation and management of the St Lucia system, leading to the recent initiation of a project in support of its rehabilitation and long-term sustainability. This timely volume provides a unique source of information on the functioning and management of the estuary for researchers, students and environmental managers. The insights and experiences described build on over 60 years of study and management at the site and will serve as a valuable model for similar estuaries around the world.

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.
