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 important and exciting title represents the first authoritative volume focussed on pelagic (open ocean) sharks as a group. Virtually every pelagic shark expert in the world has contributed to this landmark publication which includes the latest data and knowledge on pelagic shark biology, fisheries, management, and conservation. Pelagic sharks face unprecedented levels of exploitation in all the world's oceans through both direct fisheries and by-catch, and effective management for these species is contingent upon solid science and data, which this book brings together for the first time. All those involved in shark biology will need to have a copy of this book.

The Indian Ocean and its Role in the Global Climate System provides an overview of our contemporary understanding of the Indian Ocean (geology, atmosphere, ocean, hydrology, biogeochemistry) and its role in the climate system. It describes the monsoon systems, Indian Ocean circulation and connections with other ocean basins. Climatic phenomena in the Indian Ocean are detailed across a range of timescales (seasonal, interannual to multi-decadal). Biogeochemical and ecosystem variability is also described. The book will provide a summary of different tools (e.g., observations, modeling, paleoclimate records) that are used for understanding Indian Ocean variability and trends. Recent trends and future projections of the Indian Ocean, including warming, extreme events, ocean acidification and deoxygenation will be detailed. The Indian Ocean is unique and different from other tropical ocean basins due to its geography. It is traditionally under-observed and understudied, yet plays a fundamental role for regional and global climate. The vagaries of the Asian monsoon affect over a billion people and a third of the global population live in the vicinity of the Indian Ocean. It is also particularly vulnerable to climate change, with robust warming and trends in heat and freshwater observed in recent decades. Advances have recently been made in our understanding of the Indian Ocean's circulation, interactions with adjacent ocean basins, and its role in regional and global climate. Nonetheless, significant gaps remain in understanding, observing, modeling, and predicting Indian Ocean variability and change across a range of timescales. As such, this book is the perfect compendium to any researcher, student, teacher/lecturer in the fields of oceanography, atmospheric science, paleoclimate, environmental science, meteorology and geology, as well as policy managers and water resource managers. - Provides interdisciplinary content with a comprehensive overview for students and practitioners from a wide range of disciplines as well as for stakeholders - Presents a broad overview and background on the current state of knowledge of the variability, change, and regional impacts of the Indian Ocean - Includes links to animations, slideshows, and other educational resources

Protection and sound management of coastal and marine areas are acknowledged as important mechanisms for alleviating poverty in the developing tropics. Tanzania has had considerable practical experience with a diversity of models that rely on private sector partnerships, community co-management regimes, and government-led initiatives for marine protection. 'Blueprint 2050' outlines a vision of what a protected area system could look like in 50 years. It draws on state-of-the-art ecosystem, socioeconomic, financial, and institutional background studies to paint a picture that emphasizes community-based adaptive co-management within a flexible system of eight protected area networks, one of which is the Exclusive Economic Zone. 'Blueprint 2050 is an impressive piece of professional work which addresses the plight of the many communities whose livelihoods depend on Tanzania's marine resources. Environmental conservation, sustainability, efficiency, good governance, and a pro-poor policy stance come out as key issues in pursuit of Tanzania's millennium development goals by these communities.' -- Hon Raphael OS Mollel, Senior Permanent Secretary Vice President's Office, United Republic of Tanzania 'It is my sincere hope that Blueprint 2050 will serve the intended purpose of promoting the devlopment of marine protected areas based on our current policies and legislation.' -- Hon Madam Rahma M Mshangama, Principal Secretary Ministry of Agriculture Natural Resources, Environment and Co-operatives (MANREC), Zanzibar
