Book Description
This is the sixteenth issue in the FAO series of worldwide annotated and illustrated catalogues of major groups of organisms that enter marine fisheries. It contains the 159 species in 15 genera known from the serranid subfamily Epinephelinae, including one species new to science. There is an introductory section with general remarks on habitat and fisheries of the family, a glossary of technical terms, an illustrated key to each genus and all species, and a detailed account for all species. Species accounts include an illustration of each species, scientific and vernacular names, and information on habitat, biology, fisheries, size, relevant literature, and distribution.

Book Description
Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.

Book Description
Coral reefs are among Earth's most diverse, productive, and beautiful ecosystems, but until recently, their ecology and the means to manage them have been poorly understood and documented. In response to the inadequate information base for coral reefs, this book reviews the ecological and conservation status of coral reefs of the Western Indian Ocean, bringing together presentations of the region's leading scientists and managers working on coral reefs. Coral Reefs of the Indian Ocean: Their Ecology and Conservation starts with a general overview of the biogeography of the region and a historical account of attempts to conserve this ecosystem. It goes on to describe the state of the reefs in each of the countries with coral reefs, and it concludes with a series of management case studies. The book also summarizes most of the existing ecological information on reefs in this region and efforts at management, making it useful for students, teachers, and investigators interested in tropical or marine ecology, conservation biology and management, and environmental sciences.

Book Description
The three sections of this book provide an up-to-date review of the most important studies regarding groupers throughout the world. Section I, Biology, includes classification and phylogenic relationships, geographical distribution and life history. Section II, Ecology, describes how life history characteristics determine patterns of occurrence and abundance in space and time and how this affects population structure and connectivity. Section III, Conservation, covers the major threats faced by groupers, providing case studies and what the future holds for groupers.
