Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.

The Bering Sea, which lies between the United States and Russia, is one of the most productive ecosystems in the world and has prolific fishing grounds. Yet there have been significant unexplained population fluctuations in marine mammals and birds in the region. The book examines the Bering Sea ecosystem's dynamics and the relationship between man and the ecosystem, in order to identify potential reasons for the population fluctuations as well as identify ways the Sea's living resources can be better managed by government.

Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

This publication gives an updated review of the quantity of discards in the world's marine fisheries, using information from a broad range of fisheries in all continents. A number of policy issues are discussed including a 'no discards' approach to fisheries management, the need for balance between bycatch reduction and bycatch utilisation initiatives, and concerns arising from incidental catches of marine mammals, birds and reptiles. The report also highlights the need for more robust methods of estimating discards, and the development of bycatch management plans.

Food Safety is an increasingly important issue. Numerous foodcrises have occurred internationally in recent years (the use ofthe dye Sudan Red I; the presence of acrylamide in various friedand baked foods; mislabelled or unlabelled genetically modifiedfoods; and the outbreak of variant Creutzfeldt-Jakob disease)originating in both primary agricultural production and in the foodmanufacturing industries. Public concern at these and other eventshas led government agencies to implement a variety of legislativeactions covering many aspects of the food chain. This book presents and compares the HACCP and ISO 22000:2005food safety management systems. These systems were introduced toimprove and build upon existing systems in an attempt to addressthe kinds of failures which can lead to food crises. Numerouspractical examples illustrating the application of ISO 22000 to themanufacture of food products of animal origin are presented in thisextensively-referenced volume. After an opening chapter whichintroduces ISO 22000 and compares it with the well-establishedHACCP food safety management system, a summary of internationallegislation relating to safety in foods of animal origin ispresented. The main part of the book is divided into chapters whichare devoted to the principle groups of animal-derived foodproducts: dairy, meat, poultry, eggs and seafood. Chapters are alsoincluded on catering and likely future directions. The book is aimed at food industry managers and consultants;government officials responsible for food safety monitoring;researchers and advanced students interested in food safety.
