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.

This exciting new book grew out of an international symposium held at FAO, Rome in July 2008, but it is not just a collection of papers from that symposium. Rather, the publication brings together work on social-ecological marine research that cuts across disciplines, identifies key common elements and approaches that promote resilience of marine social-ecological systems in the face of global changes, and points to next steps. The book comprises contributions on conceptual issues relating to social-ecological responses in marine systems to global changes; offers illustrative case studies of specific examples of social-ecological responses in marine systems to significant environmental changes manifested locally; develops a syntheses between natural and social scientists on the topic, and points the way forward with innovative approaches to the use of science and knowledge in management, policy and advice. World Fisheries is part of Wiley-Blackwell's prestigious Fish and Aquatic Resources Series, and encompasses chapters from many scientists at the top of their fields worldwide. Carefully drawn together and edited by four world experts in the area, World Fisheries is a landmark publication which is an essential purchase for all fisheries managers worldwide.

Co-published with the Food and Agriculture Organization of the United Nations. Fisheries management is the process that has evolved to try to ensure that fisheries operate in a manner that provides the immediate benefits in a sustainable manner. The widely accepted goal is that the full range of benefits should not only be available for this generation but for generations to come. Fisheries management has been successful in some cases but there have also been many, many cases of failure. This volume is intended to contribute to improving this unsatisfactory state by addressing the widespread need for information and guidance on the broad and often complex task of fisheries management. It is an updated and expanded edition of the first version of'A fishery manager's guidebook'which was published as a FAO Fisheries Technical Paper in 2002. The major part of this new edition is divided into five parts intended to cover the range of concerns, tools and techniques essential to the modern fisheries manager, whether that manager is an individual or a formal or informal group. Following the Introduction: Part I examines the primary dimensions of fisheries: biological, ecological, social and economic Part II looks at the legal and institutional characteristics of fisheries Part III explores the tools that fishery managers have to achieve the objectives expected from a fishery Part IV discusses the role of scientific information of indicators and reference points Part V moves into implementation of fisheries management and includes a chapter on special considerations in small-scale fisheries This landmark publication is aimed at fishery managers and scientists. All libraries in research establishments and universities where fisheries and aquatic sciences are studied and taught will need copies of this important volume. Fisheries around the world make essential contributions to human well-being including the provision of basic food supplies, employment, recreational opportunities, foreign currency and others, providing benefits to hundreds of millions of people. Despite these benefits, our record of managing fisheries so that the benefits can be sustained has been poor, at best, and most fisheries around the world are experiencing serious ecological, social or economic problems and usually all three. Today there is global concern about the state of fishery resources and aquatic ecosystems, their resilience to future stresses such as climate change and their ability to continue to provide benefits.

Coastal waters around the globe suffer from strain due to a wide range of human activities.

Pathology and Epidemiology of Aquatic Animal Diseases for Practitioners Comprehensive reference on the diseases and applied epidemiology of all aquatic animal taxa, including invertebrates and vertebrates Pathology and Epidemiology of Aquatic Animal Diseases for Practitioners provides information on the diseases and applied epidemiology of all aquatic animal taxa, including invertebrates and vertebrates, along with information on applied epidemiology, acknowledging the One Health concept, and discussion on probabilities of disease outbreaks occurring and assesses the economic costs of treating those outbreaks, if applicable. Divided into two sections, the book looks at the pathology of major aquatic taxa and their associated infectious diseases—parasitic, viral, and bacterial—and non-infectious diseases. Each includes an overview, their host range and transmission, signs and diagnosis, differentials, and treatment and management. These assets are accompanied by clinical signs-lesion differential charts. Sample topics discussed in Pathology and Epidemiology of Aquatic Animal Diseases include: Echinoderms, including crinoidea (crinoids, sea lilies, feather stars, and asteroidea), sea stars/starfish, and ophiuroidea (brittle stars and basket stars) Reptiles, including turtles (freshwater and marine), crocodilians, marine iguanas, and sea snakes Pinnipeds, including otariidae (eared seals), odobenidae (walruses), phocidae (earless seals), mustelidae (otters), and sirenia (manatees and dugongs) Tropical marine aquarium fish (damselfish, angelfish, gobies, wrasses, parrotfish, butterfly fish, and clownfish) and anemones. A highly useful reference for veterinary practitioners, academic staff, and researchers, Pathology and Epidemiology of Aquatic Animal Diseases is also suitable for those who are interested in aquatic veterinary medicine and serves as a companion to Fundamentals of Aquatic Veterinary Medicine, written by the same editorial team.
