Book Description
In many ways, this book is the culmination of more than four decades of my exp- ration of the taxonomy, biogeography and ecology of New Zealand’s quite small freshwater fish fauna. I began this firstly as a fisheries ecologist with the New Zealand Marine Department (then responsible for the nation’s fisheries research and mana- ment), and then with my PhD at the Museum of Comparative Zoology at Harvard University, Cambridge, MA, USA in the early–mid 1960s. Since then, employed by a series of agencies that have successively been assigned a role in fisheries research in New Zealand, I have been able to explore very widely the natural history of that fauna. Studies of the fishes of other warm to cold temperate southern lands have followed, particularly southern Australia, New Caledonia, Patagonian South America, the Falkland Islands, and South Africa and, in many ways, have provided the rather broader context within which the New Zealand fauna is embedded in terms of geography, phylogeny, and evolutionary history, and knowing this context makes the patterns within New Zealand all the clearer. An additional stream in these studies, in substantial measure driven by the beh- ioural ecology of these fishes round the Southern Hemisphere, has been exploration of the role of diadromy (regular migrations between marine and freshwater biomes) in fisheries ecology and biogeography, and eventually of diadromous fishes wor- wide.

Book Description
Diver, undersea explorer and passionate conservationist Wade Doak has lived near the Tutukaka coast with wife Jan since 1968. Well known for his pioneering dives at the Poor Knights Islands off the coast of Whangarei, Wade has gradually shifted his focus over the years from the sea to the land. He and Jan have spent years exploring the shoreline and estuaries, walking cliff-top paths, studying the mangroves and roaming the forest. Wade's engaging text tells a remarkable story, illustrated with an incredible photographic archive of trees, shrubs, vines, orchids, ferns, birds, and attendant wildlife, displaying an area rich in diversity. With intensive pest control, the Doaks have witnessed a dramatic recovery of the native flora and fauna. In 'their coastal slice' the natural world has returned with a profusion of birdsong in the forest. This book is a plea for the conservation and protection of New Zealand's wildernesses, reiterating the challenge made by Sir Paul Callaghan: can we eradicate pests throughout our island nation? On a small scale, Wade and Jan Doak show that yes, it can be done.

Book Description
This book describes the fish which exhibit diadromy, their life history strategies and the implications for fisheries. The book should therefore represent an important volume for workers in fish biology, animal physiology and behaviour, and fisheries.

Book Description
Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.

Book Description
With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Book Description
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.

Book Description
Since the publication of The Migrations of Fish by Prof. Alexander Meek in 1916, a number of books have been published on this subject. However, most of these books only cover one type of migratory mechanisms. This book aims to overcome this drawback by presenting a comprehensive coverage of all life history strategies-potadromy, anadromy, catadrom
