The species of hake, making up the genus Merluccius, are commercially important and currently largely over exploited, with many stocks badly depleted and showing only limited signs of recovery. From the end of the 1990s, concepts such as sustainability, ecosystem-based approaches to fisheries management, a code for the responsible conduct for fisheries, governance and others have emerged or have been considered by politicians, stakeholders and society. Moreover, new tools for stock assessment have been developed. But many hake stocks of the genus Merluccius show no sign of restoration. Hakes: Biology and Exploitation brings together a wealth of important information on the biology and exploitation of hake and hoki stocks around the world. Each chapter provides an overview of the fisheries of each species in an ecological and environmental context, looking at stock distribution, characteristics of the environment, life history, reproduction, diet, growth, mortality, pricing and markets of each geographical region and the hake species found there. With chapters written by regional experts on hake species and included within Wiley-Blackwell’s prestigious Fish and Aquatic Resources Series, Hakes: Biology and Exploitation provides up-to-date and comparative information, including new approaches to fisheries management, for all those involved in fisheries management, aquatic ecology and biological sciences.

This book provides an overview of innovative and new directions being chartered in South African tourism geographies. Within the context of global change the volume explores different facets and different geographies of tourism. Key themes under scrutiny include the sharing economy, the changing accommodation service sector, touring poverty, tourism and innovation, tourism and climate change, threats to sustainability, inclusive tourism and a number of studies which challenge the present-mindedness of much tourism geographical scholarship. The 18 chapters range across urban and rural landscapes in South Africa with sectoral studies which include adventure tourism, coastal tourism, cruise tourism, nature-based tourism, sports tourism and wine tourism. Finally, the volume raises a number of policy and planning issues in the global South in particular relating to sustainability, local economic development and poverty reduction. Outlining the impact of tourism expansion in South Africa and suggesting future research directions, this stimulating book is a valuable resource for geographers as well as researchers and students in the field of tourism studies.

Penguins, among the most delightful creatures in the world, are also among the most vulnerable. The fragile status of most penguin populations today mirrors the troubled condition of the southern oceans, as well as larger marine conservation problems: climate change, pollution, and fisheries mismanagement. This timely book presents the most current knowledge on each of the eighteen penguin species-from the majestic emperor penguins of the Antarctic to the tiny blue penguins of New Zealand and Australia, from the northern rockhopper penguins of the South Atlantic and Indian Oceans to the Galapagos penguins of the equator-written by the leading experts in the field. Included for each species: o Life history o Distribution, population sizes and trends o International Union for the Conservation of Nature (IUCN) status o Threats to survival o Legal protection The book also provides information on current conservation efforts, outlines the most important actions to be taken to increase each population's resilience, and recommends further research needed to protect penguins and the living creatures that share their environment. Beautifully illustrated with full-color photographs of each species in their natural habitat and detailed charts and graphs, Penguins will be an invaluable tool for researchers, conservation groups, and policy makers. It will also enchant anyone interested in the lives or the plight of these fascinating animals. Watch the trailer: http://www.youtube.com/watch?v=0s0BbIU6cqE&feature=plcp

As we search urgently for a strategy of sustainable natural resource management, an international debate is brewing over destructive modern fishery methods. Namibia's Fisheries is a timely contribution to this discussion as it examines Namibia's Benguela upwelling system, an area that supports traditional and modern forms of fishery. This volume analyzes the Namibian experience in fishery management, featuring essays by researchers, Namibian fishery managers, and international specialists that cover a range of ecological and social issues. Namibia's Fisheries will be a valuable resource for researchers, conservationists, and students of fishery management.

Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
