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
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
Geography, politics, and other factors have allowed Cuba to preserve the region's most pristine coast and offshore marine environment. Deep Cuba recounts Bill Belleville's month-long journey around the island in the company of American and Cuban marine biologists and a Discovery Channel film crew. It was the first, and so far only, United States submersible research expedition in Cuban waters. From coral reefs to mangrove swamps to a submerged volcanic mountain, the voyagers encountered sublimely wild places unseen before by anyone from the United States—or even by many Cubans. Belleville conveys the tempo of the scientists' workday, during which the routine gathering of data and specimens could be punctuated by trips in a state-of-the-art submersible, the discovery of new species, or a tropical storm. Throughout the trip, as well, all on board had to work through differences that arose from the expedition's contrary goals: to produce a commercially viable seagoing adventure film and to conduct controlled, methodical scientific investigations. Belleville paces his coverage of the expedition with absorbing stories about the history and culture of the island's peoples, from the indigenous Taino to its current inhabitants of African and European heritage. Deep Cuba even includes a candid portrait of Castro himself. An avid diver, sport fisherman, and naturalist, El Comandante paid a visit aboard the research vessel. Deep Cuba is an engaging mix of nature and travel writing, along with scientific reportage that is keenly attuned to current crises in research funding. Revealed here is a magnificent marine world with crucial ecological links to the Caribbean Basin and the southeastern United States.

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
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).
