Book Description
A useful tool for understanding the broad-ranging effects of changing environmental conditions in aquatic ecosystems, Theory and Application in Fish Feeding Ecology links theoretical and practical aspects of fish foraging research. Fish feeding experts share their recent research, filling the gaps between contemporary information and theoretical issues. The twenty essays in this volume examine foraging theory, habitat gradients and landscape ecology, disturbance, and invasive species. Theory and Application in Fish Feeding Ecology integrates recently uncovered information with current techniques to address the many problems involved in the management of fishery resources.

Book Description
Fish are one of the most important global food sources, supplying a significant share of the world’s protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity—insights that classic age-based theory can’t provide—and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.

Book Description
Feeding Ecology of Fish establishes a comprehensive framework for the variable ecological patterns exemplified by feeding fishes. The author, a former president of the American Fisheries Society, devotes special attention to synthesizing empirical studies in categorizing feeding patterns. This book shows how remarkably adaptable fish can be with regard to selecting food, often from trophic levels not usually occupied. Relying on a thorough literature survey, Feeding Ecology of Fish will be an invaluable reference for both fishery scientists and ecological theorists. - Organization by trophic level - Emphasis on empirical studies - Broad coverage of a diverse field

Book Description
Nearly a decade ago I began planning this book with the goal of summarizing the existing body of knowledge on ecology of freshwater fishes in a way similar to that of H. B. N. Hynes' comprehensive treatise Ecology of Running Waters for streams. The time seemed appropriate, as there had been several recent volumes that synthesized much information on a range of topics important in fish ecology, from biogeographic to local scales. For example, the "Fish Atlas" (Lee et aI. , 1980) had provided range maps and basic entry to the original literature for all freshwater fishes in North America, and in 1986 Hocutt and Wiley's Zoogeography of North American Fishes provided a detailed synthesis of virtually everything known about distributional ecology of fishes on that continent. Tim Berra (1981) had summarized in convenient map form the worldwide distribution of all freshwater fish families, and Joe Nelson's 1976 and 1984 editions of Fishes of the World had appeared. To complement these "big picture" views of fish distributions, the volume on Community and Evolutionary Ecology of North American Freshwater Fishes, edited by David Heins and myself (Matthews and Heins, 1987), had provided an opportunity for more than 30 individuals or groups to summarize their work on stream fishes (albeit mostly for warmwater systems).

Book Description
GUTSHOP '84 was the fourth in a series of workshops on various aspects of fish feeding (Table 1). Initially, the organizers merely invited regional (Pacific Northwest) fisheries scientists to share, and possibly develop mutual solutions to, the many technical problems associated with trying to obtain meaningful, quantitative information from fish stomach contents, and the subsequent statistical treatment and interpretation of the multivariate data. Since then, although not explicitly based upon any internal cycle, these scientists and increasingly more and more dispersed colleagues continued to congregate for workshop deliberations every two or three years. From the 49 attendees at the first workshop, the number of participants had grown to 65 at GUTSHOP '78, and 107 at GUTSHOP '81. By the third workshop, we were drawing scientists from across the U. S. and Canada, and from as far away as Norway. The topical content of the workshops has also evolved from the predominantly technical aspects of fish collection and stomach contents processing techniques, statistical analysis, and data manipulation and presentation to considerations of theoretical ecology, bioenergetics, and behavior.

Book Description
This book sets out to bridge the order scales among pike researchers, populations, communities, management, and fisheries. It emphasizes the progress of pike research during the last two decades, during which the order-bridging approach emerged. This framework underpins the text and the message, to convey its importance to pike research and to fish research in general. In addition, a considerable part of the book is devoted to management implications and highlights aspects of human dimensions in recreational fisheries.

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.
