BEHAVIOR OF MARINE FISHES BEHAVIOR OF MARINE FISHES: Capture Processes and Conservation Challenges Understanding fish behavior in relation to capture processes in marine fisheries is of fundamental importance to reducing bycatch and discards, and to enhancing marine fisheries conservation efforts. A thorough understanding of this allows commercial fishers to more effectively capture target species while reducing the catch of unwanted species. Behavior of Marine Fishes: Capture Processes and Conservation Challenges provides the reader with principles, patterns, and characteristics on fish behavior and fish capture processes using several types of important commercial fishing gears. The book also highlights conservation challenges facing the marine capture fisheries in efforts to maintain sustainable use of marine resources and to reduce negative impacts to the marine ecosystem. This volume, with contributions from leading applied fish behaviorists and fishing gear technologists from around the world, will be a valuable reference for researchers, fishing gear technologists, fisheries managers, students, and conservationists. SPECIAL FEATURES: Synthesis of current research and valuable knowledge that will help reduce bycatch and discards in commercial fisheries Review of basic fish behavioral principles and patterns and their relation to capture methods and conservation efforts Contributions from leading international applied fish behaviorists and fishing gear technologists

Electricity in Fish Research and Management, 2nd Edition provides a comprehensive discussion of the uses of both electricity and electrical principles in fishery management and research. It covers electric fishing (including theory, equipment, data analysis and practical factors affecting efficiency), fish barriers, fish counters and fish welfare issues. The book concentrates on Electric Fishing (or Electrofishing); an internationally accepted and widely used procedure for sampling fish. Over the past 50 years electric fishing has become a standard method for fishery studies and management e.g. establishing population densities and abundance. However, due to the potential hazards of the method (both to operators and fish) there is a continuing need to develop and promote best practice guidelines. The author has studied fish ecology for 40 years and understands the need for information that reaches out to all levels of understanding in the field. Previous books on this subject have either been collections of scientific papers and/or technical reports or very simple instruction manuals. In this book theory and practice is explained using non-technical language and simple equations. It brings depth as well as breadth in both information and principles behind the methods and should be an invaluable tool to both fisheries managers and researchers. Although the book is aimed at undergraduates, the clear explanation of the factors means that the book is suitable for all levels of practitioners.

Throughout history most people have associated northern North America with wilderness – with abundant fish and game, snow-capped mountains, and endless forest and prairie. Canada’s contemporary picture gallery, however, contains more disturbing images – deforested mountains, empty fisheries, and melting ice caps. Adopting both a chronological and thematic approach, Laurel MacDowell examines human interactions with the land, and the origins of our current environmental crisis, from first peoples to the Kyoto Protocol. This richly illustrated exploration of the past from an environmental perspective will change the way Canadians and others around the world think about – and look at – Canada.

Red Snapper Lutjanus campechanus, is an important commercial and recreational fish species and there has been much interest in maintaining its status among a variety of scientific, social and economic levels. Stocks are influenced by varying environmental conditions, changing fishing effort and efficiency, anthropogenic effects, inter- and intraspecific interactions, bycatch from other fisheries, and habitat alterations. Red Snapper Biology in a Changing World explores these changing factors and their potential effects on Red Snapper in the Eastern Atlantic region including the Gulf of Mexico and Southeastern U.S. The book will provide a better understanding of Red Snapper population fluctuations that will subsequently allow for better management decisions and more informed user groups in their efforts to maintain a sustainable fishery. It explores the responses Red Snapper have made, and are making, relative to their life history attributes such as early life history and adult ecology, especially attributes associated with population distribution and abundance, movement patterns, fish health issues and management success. A compendium of many papers presented at the 147th annual meeting of the American Fisheries Society in Tampa, Florida, this volume also includes additional research completed as a result of the symposium. It will be essential reading for fisheries scientists and managers, ichthyologists, resource and environmental managers, and policymakers who are involved with coastal fisheries.

Biology of Stress in Fish: Fish Physiology provides a general understanding on the topic of stress biology, including most of the recent advances in the field. The book starts with a general discussion of stress, providing answers to issues such as its definition, the nature of the physiological stress response, and the factors that affect the stress response. It also considers the biotic and abiotic factors that cause variation in the stress response, how the stress response is generated and controlled, its effect on physiological and organismic function and performance, and applied assessment of stress, animal welfare, and stress as related to model species. - Provides the definitive reference on stress in fish as written by world-renowned experts in the field - Includes the most recent advances and up-to-date thinking about the causes of stress in fish, their implications, and how to minimize the negative effects - Considers the biotic and abiotic factors that cause variation in the stress response

Revolution in the Seas: Ending Overfishing and Building Pesco-ecology, Sustainable Agro-Ecology of Fishing provides an in-depth analysis of the dynamics between humans and disrupting marine ecosystems by extracting its wild animals. It highlights practical changes that can be implemented to prevent overfishing and create a new way of fishing, the pesco-ecology that benefits marine life, coastal communities, and human consumers alike. Written by a leader in fisheries science and conservation, this book begins by diagnosing the issue of overexploitation, showing the dynamics and consequences on living marine resources and ecosystems. It then goes on to demonstrate how recent scientific discoveries, including tropic network functionality, are changing humans’ approach to fishing sustainably. The final sections are devoted to ecological, economic, and social solutions. Revolution in the Seas: Ending Overfishing and Building Pesco-ecology and Sustainable Agro-Ecology of Fishing is a vital resource for fisheries scientists, managers, academics and students in marine biology or fisheries studies. All stakeholders and citizens involved in building a sustainable relationship between humans and the sea will also benefit from this book’s revolutionary content. Translated to English for global accessibility Analyzes systems and protocols that have led to overexploitation Examines innovations and key rules for implementing a new way of fishing and rethinking sustainability
