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
Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a ‘must read’ for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.

Book Description
Increasing interest in oceanography and marine biology and its relevance to global environmental issues continues to create a demand for authoritative reviews summarizing recent research. Now in its 51st volume, Oceanography and Marine Biology has addressed this demand for more than 50 years. This annual review considers the basics of marine research, special topics, and emerging new areas. Regarding the marine sciences as a unified field, the text features contributors who are actively engaged in biological, chemical, geological, and physical aspects of marine science. Including color inserts and extensive reference lists, this series is essential for researchers and students in all fields of marine science.

Book Description
Groupers are fascinating charismatic fishes commonly found in reef habitats around the world that sustain a global multimillionaire fishery. They are an important top predator species and therefore of paramount ecological importance for reef systems' resilience. The book, Biology and Ecology of Groupers is an up-to-date review of the main bio-ecological topics involving worldwide groupers species oriented to the academic community and managers. It covers aspects of classification and phylogenetic relationships, geographical distribution, and life history related characteristics (Section I), including the major threats of groupers populations, case studies of successful management and comments about the future of groupers in our changing world (Section II).

Book Description
The local diversity and global richness of coral reef fishes, along with the diversity manifested in their morphology, behaviour and ecology, provides fascinating and diverse opportunities for study. Reflecting the very latest research in a broad and ever-growing field, this comprehensive guide is a must-read for anyone interested in the ecology of fishes on coral reefs. Featuring contributions from leaders in the field, the 36 chapters cover the full spectrum of current research. They are presented in five parts, considering coral reef fishes in the context of ecology, patterns and processes, human intervention and impacts, conservation, and past and current debates. Beautifully illustrated in full-colour, this book is designed to summarise and help build upon current knowledge and to facilitate further research. It is an ideal resource for those new to the field as well as for experienced researchers.

Book Description
A marine biologist’s “funny and entertaining” look at the mating rituals of undersea creatures (Miami Herald). Forget the Kama Sutra. When it comes to inventive sex acts, just look to the sea. There we find the elaborate mating rituals of armored lobsters; giant right whales engaging in a lively threesome while holding their breath; full moon sex parties of groupers and daily mating blitzes by blue-headed wrasse. Deep-sea squid perform inverted 69s, while hermaphrodite sea slugs link up in giant sex loops. From doubly endowed sharks to the maze-like vaginas of some whales, Sex in the Sea is a journey unlike any other to explore the staggering ways life begets life beneath the waves. Beyond a deliciously voyeuristic excursion, the book also connects the timeless topic of sex with the timely issue of sustainable oceans—revealing how overfishing, climate change, and pollution are disrupting the creative procreation that drives the wild abundance of life in the sea, and how we can promote successful sex in the sea. “Hardt’s writing is often spectacular at describing the rituals and courtships of underwater reproduction.” —The New Republic “Weird [and] excellent.” —GQ “An oceanographic Kinsey Report.” —O, The Oprah Magazine “[Readers] will find much to learn in this well-written and delightful study.” —Library Journal (starred review)

Book Description
This study brings together the work of many researchers to arrive at suggestions for solving the environmental problems caused by the long-running live-fish trade in Southeast Asia. With strong demand coming from mainland China, this trade has caused rampant over-fishing in Asia and consequent damage to outside subsistence or commercial fisheries. This work discusses the role of regional organizations in regulating the trade as well as ways to decrease nontarget fish mortality in an industry that often employs cyanide solution as a fishing tool.
