Red Snapper Lutjanus campechanus, is an important commercial and recreational fish species and there has been much interest in maintaining its status among a variety of scientific, social and economic levels. Stocks are influenced by varying environmental conditions, changing fishing effort and efficiency, anthropogenic effects, inter- and intraspecific interactions, bycatch from other fisheries, and habitat alterations. Red Snapper Biology in a Changing World explores these changing factors and their potential effects on Red Snapper in the Eastern Atlantic region including the Gulf of Mexico and Southeastern U.S. The book will provide a better understanding of Red Snapper population fluctuations that will subsequently allow for better management decisions and more informed user groups in their efforts to maintain a sustainable fishery. It explores the responses Red Snapper have made, and are making, relative to their life history attributes such as early life history and adult ecology, especially attributes associated with population distribution and abundance, movement patterns, fish health issues and management success. A compendium of many papers presented at the 147th annual meeting of the American Fisheries Society in Tampa, Florida, this volume also includes additional research completed as a result of the symposium. It will be essential reading for fisheries scientists and managers, ichthyologists, resource and environmental managers, and policymakers who are involved with coastal fisheries.

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.

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.

Biodiversity and Climate Change Adaptation in Tropical Islands provides comprehensive information on climate change, biodiversity, possible impacts, adaptation measures and policy challenges to help users rehabilitate and preserve the natural resources of tropical islands. While biodiversity and climate change of tropical islands has previously received less attention, it is ironically one of the most vulnerable regions in this regard. The core content of the work derives largely from the ideas and research output from various reputed scientists and experts who have recorded climate change impacts on aquatic and coastal life in tropical regions. Contributors have direct working experience with the tribes in some of the tropical islands. All of their expertise and information is compiled and presented in the work, including coverage related to climate change. This work highlights the ever-growing need to develop and apply strategies that optimize the use of natural resources, both on land and in water and judicious use of biodiversity. It functions as a critical resource on tropical island biodiversity for researchers, academicians, practitioners and policy makers in a variety of related disciplines. - Covers a huge range of biodiversity documentation, conservation measures and strategies that can be applied to various sectors, from forests to agriculture - Brings together expertise from researchers in the area who have direct experience in the regions described - Contains a wealth of field research related to biodiversity conservation and its applications from a variety of tropical islands
