Book Description
Water is becoming increasingly scarce. If recent usage trends continue, shortages are inevitable. Aquanomics discusses some of the instruments and policies that may be implemented to postpone, or even avoid, the onset of water crises. These policies include establishing secure and transferable private water rights and extending these rights to uses that traditionally have not been allowed, including altering in-stream flows and ecosystem functions. The editors argue that such policies will help maximize water quantity and quality as water becomes scarcer and more valuable. Aquanomics contains many examples of how this is being accomplished, particularly in the formation of water markets and market-like exchanges of water rights.Many observers see calamity ahead unless water supplies are harnessed and effectively conserved, and unless water quality can be improved. It is also clear that declining water quality is a serious problem in much of the world, as increasing human activities induce high levels of water degradation. Those who voice these concerns, argue the contributors to this volume, fail to consider the forces for improvement inherent in market political-economic systems that can address water issues. The contributors see water quality in economically advanced countries as improving, and they believe this establishes the validity of market-based approaches.

Book Description
This extensive work focuses on an important group of temperate freshwater fish, approaching the topic from the perspectives of both biology and aquaculture. It compiles the latest research on fish belonging to the Percidae family and describes in detail all biological aspects relevant to the culture of different species, including ecology, reproductive physiology, feeding and nutrition, genetics, immunology, stress physiology and behavior. It also considers commercial fish production and fish farming topics, such as protocols for induction of gonad maturation, spawning, incubation and larval rearing. Expert contributors not only provide a critical peer review of scientific literature but also original research data, and identify effective practical techniques. The book features chapters on systematics, ecology and evolution, on development, metabolism and husbandry of early life stages and on growth, metabolism, behavior and husbandry of juvenile and grow-out stages. Furthermore, the authors consider genetic improvement and domestication, as well as diseases and health management, crucial to the readers' understanding of these fish and how they can be cultured. Both researchers of percid fish biology and aquaculture professionals who are considering intensive and pond culture of percid fishes will value this timely and comprehensive handbook.)

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
Lake Erie’s south-shore tributaries, known as Steelhead Alley, offer some of the finest flyfishing opportunities for some of the biggest and most beautiful fish in the United States, which is why Wilderness Adventures Press is releasing the brand new Flyfisher’s Guide to Steelhead Alley, by Daren Niemi. Battles won and lost with these silver warriors are recounted time and again around dinner tables or campfires, over beer or whiskey. The fish have almost a mythical stature, uncommon amongst other gamefish, so much so that they seem to occupy the space between truth and legend. The author has over three decades of experience on these spectacular fisheries, and he shares his catalog of knowledge in this comprehensive new book. From the Vermillion River in Ohio to Elk Creek in Pennsylvania up through Cattaraugus Creek near Buffalo, New York, he covers the whens, wheres, and hows to get readers into the fish of a lifetime. Niemi also covers the gear, fish habits and habitat, timing, reading the water, techniques and much more. This book comes with Wilderness Adventures Press’ precise and detailed full-color maps, with GPS coordinates for all access points, boat ramps, and parking areas, along with access roads, public land and more. As Lefty once said: “If someone can’t find locations from these maps they need to stay home.” There is no better source for this information than the all-new Flyfisher’s Guide to Steelhead Alley.

Book Description
This volume focuses on the US-Canadian experience with the shared fishery resources of the Laurentian Great Lakes, a vast and complex ecosystem that holds 20 percent of the world's surface fresh water supply and a wide array of fish and fisheries. Written by scientists from federal, state, and provincial management agencies, contributions address current knowledge of the ecological, sociological, and policy issues that face the region's fishery managers and policy makers in both countries. Lacks a subject index.

Book Description
One of the Great Lakes region’s most precious natural resources is its fishery, with its intricate web of aquatic life, the environments it inhabits, and the people who use and enjoy these areas. The Great Lakes fishery supports not only an important commercial fishing industry but also tourism in eight different states and two countries, attracting millions of recreational anglers each year. As valuable as the fishery is, it is equally fragile. Since the 1950s, state, provincial, and federal agencies have coordinated efforts to manage the fishery and protect it from a range of threats, from the spread of invasive species to nutrient pollution to habitat destruction. Now in its fourth edition, The Life of the Lakes examines the complex portrait of the Great Lakes fishery, including the history of the fishery’s exploitation and management, the current health of the Lakes, and the outlook for the future. Featuring more graphics, photos, and illustrations than ever, all printed in full color, the new edition of this engaging book is a perfect resource for general readers, teachers, and students looking for an easy-to-follow guide to the Great Lakes fishery. This book is published in collaboration with Michigan Sea Grant (www.michiganseagrant.org), a cooperative program of the University of Michigan and Michigan State University.
