This report updates previous studies that measured in economic terms the extent of biological losses attributable to overfishing globally. The new estimates assess these 'sunken billions' at $83 billion annually. The report further shows that a clear path can lead to the recovery of these considerable losses, including through significant reduction in global fishing overcapacity. A breakdown between regions is also included, showing that the effort needed to achieve this reform will not be felt equally throughout the world. While the cost of such reform will likely be high, the expected benefits include an increase in biomass by a factor of 2.7, increase in annual harvests by 13 percent, and a 30-fold increase in annual net benefits accrued to the fisheries sector (from $3 billion to $86 billion annually). This urgent call for action is reinforced by the impacts of climate change on fish stocks and fisheries worldwide.

This report indicates that climate change will significantly affect the availability and trade of fish products, especially for those countries most dependent on the sector, and calls for effective adaptation and mitigation actions encompassing food production.

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.

Potentially harmful contact between fisheries and marine vulnerable species represents a global conservation issue and efforts to mitigate the negative repercussions of these interactions belong in strategies for ensuring the sustainability of fisheries. This literature review offers a survey of mitigation measures and techniques that have been developed and tested around the world, aiming to address both the incidental catch of highly mobile species – specifically, cetaceans, seabirds, sharks and rays, and sea turtles – and depredation caused by dolphins. Based on research detailed in over 300 documents, including peer-reviewed publications, reports from international organizations and papers available on the internet, most of the mitigation techniques illustrated are still under development, with only a few already adopted through legislation. The selected mitigation measures are grouped by main types of fishing gear – gillnets and trammel nets, longlines and lines, trawls, purse seines, traps and pots – and further subdivided according to which of the four main groups of vulnerable species – cetaceans, seabirds, sharks and rays, or sea turtles – they are designed to protect. Preventive and curative approaches covering both technical measures (gear modifications, strategies, as well as acoustic, visual, magnetic and chemosensory deterrents) and management measures are described.

This book focuses on how marine systems respond to natural and anthropogenic perturbations (ENSO, overfishing, pollution, tourism, invasive species, climate-change). Authors explain in their chapters how this information can guide management and conservation actions to help orient and better manage, restore and sustain the ecosystems services and goods that are derived from the ocean, while considering the complex issues that affect the delicate nature of the Islands. This book will contribute to a new understanding of the Galapagos Islands and marine ecosystems.​

The 2nd international tagging and tracking symposium was held in San Sebastian, Spain, in October 2007, seven years after the first symposium was held in Hawaii in 2000 (Sibert and Nielsen 2001). In the intervening seven years, there have been major advances in both the capability and reliability of electronic tags and analytical approaches for geolocation of tagged animals in marine habitats. Advances such as increased data storage capacity, sensor development, and tag miniaturization have allowed researchers to track a much wider array of marine animals, not just large and charismatic species. Importantly, data returned by these tags are now being used in population analyses and movement simulations that can be directly utilized in stock assessments and other management applications. Papers in this volume are divided into three sections, the first describing insights into behavior achieved using acoustic, archival, and novel tags, the second reporting on advances in methods of geolocation, while the final section includes contributions where tag data have been used in management of marine species. Accurate documentation of animal movements and behaviors in critical marine habitats are impossible to obtain with other technologies. The management and conservation of marine species are critical in today’s changing ocean environment and as electronic tags become more accurate and functional for a diversity of organisms their application continues to grow, setting new standards in science and technology.

The fishing industry benefits the people and economies of the Pacific in various ways but the full value of these benefits is not reflected in the region's statistics. Records may be maintained but they are not complete, or accurate, or comparable. The research summarized in this report reaffirms the importance of this sector to the economies and societies of the Pacific island countries. The research reveals that the full value of fisheries is likely to have eluded statisticians, and therefore fisheries authorities, government decision makers, and donors. But its value has never escaped the fisher, fish trader, and fish processor. The difference in appreciation between public and private individuals must raise the question of whether fisheries are receiving adequate attention from the public sector---including the necessary management and protection, appropriate research, development, extension and training, and sufficient investment.

"Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.
