This book provides cutting-edge scientific idea and novel concepts on the ecosystem-based approach to fisheries management. It begins by reviewing the scientific fundamentals and problems currently faced by conventional fisheries science, based on population dynamics. In turn, it reviews the theoretical basis of ecosystem dynamics, including selected ecosystem indicators. Surplus production and balanced harvests are discussed in the ecosystem dynamics context. Several ecosystem-holistic indicators are described, but particular emphasis is placed on two: the noxicline (gain in entropy due to loss of biomass) and resilience, which are expressed as ecosystem (holistic) points of reference for defining allowable harvest rates. Both biological (population) and ecosystem (holistic) points of reference are subsequently analyzed in the context of fisheries management and conservation. An adaptability concept is also discussed as a management policy for facing climate change. In closing, the concepts presented are applied to six study cases involving a range of different ecosystems and fisheries.

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.

"By examining a suite of over 90 indicators for nine major U.S. fishery ecosystem jurisdictions, Link and Marshak systematically track the progress the U.S. has made toward advancing ecosystem-based fisheries management (EBFM) and making it an operational reality. Covering a range of socioeconomic, governance, environmental forcing, major pressures, systems ecology, and fisheries criteria, they evaluate progress toward EBFM in the U.S., covering a wide range of longitude, latitude, and parts of major ocean basins, representing over 10% of the world’s ocean surface area. They view progress toward the implementation of EBFM as synonymous with improved management of living marine resources in general, and highlight lessons learned from a national perspective. Although US-centric, the lessons learned are applicable for all parts of the global ocean. Though much work remains, significant progress has been made to better address many of the challenges facing the sustainable management of our living marine resources"--Publisher's description.

The purpose of the dissertation research was to improve understanding of factors contributing to or preventing progress on ecosystem-based fisheries management (EBFM) implementation for the Mid-Atlantic Fishery Management Council (MAFMC) and the New England Fishery Management Council (NEFMC), focusing on Council member and stakeholder beliefs, attitudes, and understanding. The Coorientation Model and the Planning Table were used to guide inquiry into the research objectives. The Coorientation Model was used to measure the degree of understanding between Council members and stakeholders. The concept of the Planning Table addressed whose interests were voiced, acknowledged, and incorporated into planning decisions. Council meetings were observed and 66 individuals were interviewed, including Council members, Council staff members, and Scientific and Statistical Committee (SSC) members in the New England (NE) and Mid-Atlantic (MA) regions, about EBFM. Additionally, more than 5,600 surveys were sent to commercial fishermen, recreational anglers, non-governmental organization leaders, SSC members and MAFMC and NEFMC members in the NE and MA regions about EBFM and over 1,000 responses were received. Neither low agreement nor low understanding between Council members and stakeholders appeared to be a barrier to NEFMC or MAFMC transition to EBFM. Council members and stakeholders responded that there are needs for social science information for EBFM and that although Council members and stakeholders perceive major barriers to EBFM, Council members and stakeholders do not perceive that these challenges are insurmountable. The study highlights specific barriers, social science needs, time lines and recommendations that MAFMC and NEFMC decision makers could focus on to facilitate the transition from single species fisheries management to EBFM. Specifically, decision makers and stakeholders recommend the development of a pilot plan for EBFM. Overall, managers and stakeholders in both the NE and MA regions generally agreed that EBFM is a holistic approach to fisheries management which includes biological, environmental, and human factors, and that the Councils should gradually transition to a management plan that reflects EBFM.

Showing how big-picture patterns can help overcome the failures of conventional management, this book is ideal for students, researchers and professionals involved with marine fisheries. It explores not only the current practice of the 'ecosystem approach' to fisheries management but also its critical importance to even larger perspectives. The first section gives a valuable overview of how more and more of the complexity of real-world systems is being recognized and involved in the management of fisheries around the world. The second section then demonstrates how important aspects of real-world systems, involving population dynamics, evolution and behavior, remain to be taken into account completely. This section also shows how we must change the way we think about our involvement in, and the complexity of, marine ecosystems. The final chapters consider how, with the use of carefully chosen macroecological patterns, we can take important steps towards more holistic management of marine fisheries.

Ecosystems are complex and dynamic natural units that produce goods and services beyond those of benefit to fisheries. Because fisheries have a direct impact on the ecosystem, which is also impacted by other human activities, they need to be managed in an ecosystem context. The meaning of the terms "ecosystem management", "ecosystem-based management", "ecosystem approach to fisheries" (EAF), etc., are still not universally defined and progressively evolving. The justification of EAF is evident in the characteristics of an exploited ecosystem and the impacts resulting from fisheries and other activities. The rich set of international agreements of relevance to EAF contains a large number of principles and conceptual objectives. Both provide a fundamental guidance and a significant challenge for the implementation of EAF. The available international instruments also provide the institutional foundations for EAF. The FAO Code of Conduct for Responsible Fisheries is particularly important in this respect and contains provisions for practically all aspects of the approach. One major difficulty in defining EAF lies precisely in turning the available concepts and principles into operational objectives from which an EAF management plan would more easily be developed. The paper discusses these together with the types of action needed to achieve them. Experience in EAF implementation is still limited but some issues are already apparent,e.g. in added complexity, insufficient capacity, slow implementation, need for a pragmatic approach, etc. It is argued, in conclusion, that the future of EAF and fisheries depends on the way in which the two fundamental concepts of fisheries management and ecosystem management, and their respective stakeholders, will join efforts or collide.

"Sustainable use of aquatic ecosystems is high on regional, national and international agendas and central to the implementation of international agreements on biological diversity, responsible fisheries and fish stock management. Since 2001, when political commitments were made to implement the ecosystem approach, countries have begun to incorporate ecosystem considerations into their fisheries management and have met with varied success." "The Ecosystem Approach to Fisheries covers both theoretical andapplied aspects of sustainable management, with a particular emphasis on reviewing concepts and addressing implementation issues in the form of case studies from around the world. Personal experiences are considered from diverse backgrounds and discuss the constraints encountered, strategies identified and best practices to facilitate further implementation."--BOOK JACKET.

Conventional management approaches cannot meet the challenges faced by ocean and coastal ecosystems today. Consequently, national and international bodies have called for a shift toward more comprehensive ecosystem-based marine management. Synthesizing a vast amount of current knowledge, Ecosystem-Based Management for the Oceans is a comprehensive guide to utilizing this promising new approach. At its core, ecosystem-based management (EBM) is about acknowledging connections. Instead of focusing on the impacts of single activities on the delivery of individual ecosystem services, EBM focuses on the array of services that we receive from marine systems, the interactive and cumulative effects of multiple human activities on these coupled ecological and social systems, and the importance of working towards common goals across sectors. Ecosystem-Based Management for the Oceans provides a conceptual framework for students and professionals who want to understand and utilize this powerful approach. And it employs case studies that draw on the experiences of EBM practitioners to demonstrate how EBM principles can be applied to real-world problems. The book emphasizes the importance of understanding the factors that contribute to social and ecological resilience —the extent to which a system can maintain its structure, function, and identity in the face of disturbance. Utilizing the resilience framework, professionals can better predict how systems will respond to a variety of disturbances, as well as to a range of management alternatives. Ecosystem-Based Management for the Oceans presents the latest science of resilience, while it provides tools for the design and implementation of responsive EBM solutions.

Ecosystem-based fishery management inherently involves confronting tradeoffs and requires taking a holistic approach to evaluating and developing fisheries management strategies that look beyond single-species harvest management. The goal of this study was to identify ecological tradeoffs that arise through predator-prey interactions, tradeoffs between conflicting management objectives, and tradeoffs associated with marine protected areas. To accomplish this, I developed a trophic-dynamic ecosystem model of the West Florida Shelf with particular emphasis on the reef fish component (groupers and snappers) of the fish community, using Ecopath with Ecosim and Ecospace.
