SUSTAINABLE FISHERY SYSTEMS

An up-to-date and interdisciplinary guide to sustainable fisheries

Fisheries, whether small-scale or large-scale, are filled with complexity and uncertainty. Making the right decisions to successfully manage fisheries for sustainability and resilience requires a systems approach - including both natural and human elements, and their many interactions. To understand fisheries, and how they change over time, a diverse range of fishery knowledge must be brought together.

Sustainable Fishery Systems, 2nd edition meets these needs. The new edition provides essential information that can be readily applied within government, community, industrial, academic and research settings.

Sustainable Fishery Systems, 2nd edition retains the first edition’s emphasis on themes such as sustainability, resilience, uncertainty, complexity, and conflict, and expands its treatment of topics that have, since the first edition’s publication, become crucial to consider in the field of fisheries. As a result, readers will find: - Updated and expanded coverage of topics including coastal conservation, ecosystem-based management, co-management, community-based management, and more - New chapters covering connections between fisheries and marine protected areas, biodiversity conservation, climate and fisheries, and multi-sectoral management - A more detailed introduction to the “systems” perspective of fisheries, reflecting the substantial growth in that subject’s importance, and covering in detail the natural, human and governance aspects of fisheries.

Sustainable Fishery Systems, 2nd edition is an indispensable interdisciplinary resource for educators, researchers, government agencies, and fisheries managers.
