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.

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.

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.

Quantifying Diets of Wildlife and Fish presents different techniques available to study animal diets. Ecologists determine animal diets to build natural history knowledge, test hypotheses in ecological theory and make informed management decisions for important ecosystems. Many researchers use techniques traditionally applied to the animals they study, rather than techniques with the greatest potential for the aims of each project. In an effort to encourage researchers to consider new approaches, this book focuses on the techniques, rather than on particular groups of organisms or specific environments. With contributions from leading ecologists, chapters explore experimental design, observational techniques (including new technologies), stomach contents and faecal analysis, eDNA, tracers and stable isotopes. They also cover the latest multivariate methods of analyses suitable for describing animal diets and feeding relationships, as well as testing hypotheses relevant to ecological theory, environmental management and biological conservation. The expert knowledge provided will encourage readers to look beyond the boundaries of their specialties, assist in testing important hypotheses and provide insights into management problems. The examples in this book cover a range of vertebrates and invertebrates, as well as different environments, to open these methods up for novice ecologists and stimulate lateral thinking in more experienced researchers.

This volume provides a current synthesis of theoretical and empirical food web research. Whether they are binary systems or weighted networks, food webs are of particular interest to ecologists in providing a macroscopic view of ecosystems. They describe interactions between species and their environment, and subsequent advances in the understanding of their structure, function, and dynamics are of vital importance to ecosystem management and conservation. Aquatic Food Webs provides a synthesis of the current issues in food web theory and its applications, covering issues of structure, function, scaling, complexity, and stability in the contexts of conservation, fisheries, and climate. Although the focus of this volume is upon aquatic food webs (where many of the recent advances have been made), any ecologist with an interest in food web theory and its applications will find the issues addressed in this book of value and use. This advanced textbook is suitable for graduate level students as well as professional researchers in community, ecosystem, and theoretical ecology, in aquatic ecology, and in conservation biology.

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.

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).

Kerr and Dickie propose the development of a new ecological theory, one that can lead to a more effective remedy for the drastic effects of heavy fishing on natural communities of organisms in both marine and freshwater environments. By plotting the densities of the biomass of all organisms in a given community by body-size classes, the authors provide empirical evidence of what they term "the biomass body-size spectrum" in the world's oceans. After examining this evidence, they propose an underlying theory of predator-prey energy transfer: larger species eat smaller species, providing energy exchange across all species within an ecosystem. Providing the first comprehensive synthesis of the energy flow within the biomass spectrum, this book demonstrates not only a new understanding of the self-organizing properties of ecological production systems but also the potential of the biomass spectrum methodology for offering practical remedies when these natural systems are exploited by humans.
