Book excerpt: This report provides an overview of the biological status of assessed stocks around the world and relates measures of stock status to the strength of fisheries management. Stock assessment outputs, consisting primarily of time series of abundance and fishing pressure relative to target reference points, were compiled for 548 marine fish and invertebrate stocks in the RAM Legacy Stock Assessment Database. Data summary methods included: global and regional mean trends of abundance and fishing pressure relative to target reference points; bivariate plots of relative abundance and fishing pressure; estimates of potential equilibrium yield foregone at current fishing pressure; and proportions of stocks in different biomass status categories. These measures of stock status were summarized at the global level as well as separated by 16 FAO Major Fishing Areas and ocean basin regions for comparison.

Download or read book The status of marine fishery stock assessments in the Asian region and the potential for a network of practitioners written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2023-12-12 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global fisheries sector in 2023 is now appreciably different compared to that of the 1970s, as are the dominant fish stocks that comprise most of the current global landings, their location and modes of their exploitation. The fisheries of South and Southeast Asia have also changed over this period and alongside their changing nature, there has been the continuous evolution of the tools and the requirements for calculating and presenting global sustainability information. This has transformed ability to assess fish stocks, use data-poor methodologies, assess multispecies fisheries and also take into account some of the complex interactions between target and non-target species and related ecosystem effects. The countries of the South and Southeast Asia region have not reported the status of stocks in a comprehensive manner to FAO and there is a need to understand how to access existing information and also build capacity to assess the fisheries of the region using appropriate tools. This review provides thematic papers on stock assessment approaches and their application to the region. The country analysis describes the data sources and assessment methods currently being applied in national fishery management areas and in smaller regions. The review contains recommendations on the needs for capacity building and how improved regional networking can provide support to the greater understanding and application of new or improved methods of stock assessment in the region.

Topics explored in Parts 2 to 4 include aquatic biodiversity; the ecosystem approach to fisheries and to aquaculture; climate change impacts and responses; the sector’s contribution to food security and human nutrition; and issues related to international trade, consumer protection and sustainable value chains. Global developments in combating illegal, unreported and unregulated fishing, selected ocean pollution concerns and FAO’s efforts to improve capture fishery data are also discussed. The issue concludes with the outlook for the sector, including projections to 2030. As always, The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to- date information to a wide audience, including policy-makers, managers, scientists, stakeholders and indeed all those interested in the fisheries and aquaculture sector.
Download or read book Improving Fish Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-02-27 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Selecting value chains for sustainable food value chain development written by Walker, C., DeMatteis, L., Lienert, A. and published by Food & Agriculture Org.. This book was released on 2021-11-19 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Value chain development can make significant contributions to achieving the Sustainable Development Goals (SDGs) because it is a powerful approach to address root causes and binding constraints that impede the sustainable development of food value chains. The first step in value chain development is selecting those value chains that, when upgraded, can have the biggest SDG impact. This publication provides practical guidelines on how to select value chains for which upgrading is feasible and impactful in terms of the potential for generating positive economic, social and environmental outcomes. The handbook describes a step-by-step process that helps to assess, compare and select value chains in a participatory and evidence-based manner. It presents a toolbox that can be customized to projects with different budgets, scopes and objectives. This publication forms part of a set of FAO handbooks on Sustainable Food Value Chain (SFVC) development, which together provide hands-on guidance for development practitioners, including international organizations, NGOs, regional bodies and national governments seeking to achieve sustainability objectives through agrifood value chain development projects.
