This review of the techno-economic performance of the main global fishing fleets discusses the outcomes from 20 country-level studies of fishing fleets from Africa, Asia, Europe, North and South America. It includes financial, socio-economic and technical information from 103 major (semi-) industrial fishing fleet segments, which are responsible for an estimated 39 percent of marine capture fisheries production worldwide. The analysis of vessel characteristics reveals substantial differences in fishing capacity (in terms of vessel length, tonnage and power) between fleet segments. An increase in the gross tonnage of average vessels was observed in fleet segments also covered in previous reviews. Substantial increases in average length overall and engine power were observed in several Asian fishing fleets. The age structure of the fishing fleets in most regions, except Asia, shows an upward trend. An analysis of the costs and earnings data showed that labour and running costs were the two main cost components for the majority of fleet segments. Ninety-two percent of 97 fleet segments reported a positive net cash flow in the year they were surveyed, in the 2016–2019 period. Net profit margins of 10 percent or more were realized by average fishing vessels in 73 percent of the fleet segments. Returns on investment (ROIs) of 10 percent or higher were realized by 61 percent of the fleet segments. The review also discusses developments in fishing technologies. These developments, along with a general increase in seafood prices, successful fisheries management in some areas, and improved fleet capacity management in Europe and North America, have all contributed to the ongoing, positive financial and economic performance of the main global fishing fleets in recent years.

This document elaborates the revised International Standard Statistical Classification of Fishing Gear (ISSCFG), as endorsed and adopted for implementation by the FAO Coordinating Working Party on Fishery Statistics (CWP) at its Twenty-fifth Session in February 2016 in Rome, Italy. The classification applies to commercial, subsistence and recreational fisheries in marine and freshwater fisheries. The document provides definitions and illustrations of the configuration and mode of operation of typical fishing gears. The primary purpose is to assist FAO Members, regional fishery bodies, as well as those working on fishery statistics and management, to correctly attribute and report fisheries catches made by different gear types. The document also contributes to the prevention, deterrence and elimination of illegal, unreported and unregulated (IUU) fishing by providing monitoring, control and surveillance personnel with information to identify the type of fishing gear with regard to licence and authorization to carry out fishing operations. Finally, the document also provides context and references for some contemporary conservation issues related to major fishing gear types; it can therefore be used as a reference text for students and researchers in fisheries and marine conservation.

This biennial report sets out a comprehensive review of world fisheries and aquaculture, as well as examining selected policy issues including capture-based aquaculture, labour standards, fisheries management and CITES, trade issues, depleted stocks recovery, deep-water fisheries, production forecasts to 2030, fisheries subsidies, and fishing capacity. Findings include that developments in world fisheries and aquaculture during recent years have continued to follow the trends that were already becoming apparent at the end of the 1990s, with capture fisheries production stagnating, aquaculture output expanding and growing concerns with regard to safeguarding the livelihoods of fishers and the sustainability of both commercial catches and the aquatic ecosystem from which they are extracted.

Several decades ago, the efforts of public administrations were concentrated on developing fisheries and aquaculture and ensuring growth in production and consumption. Then, in the 1980s, as many resources became fully or overexploited, the attention of policy-makers began to focus instead on fisheries management, in addition to development of aquaculture. Subsequent recognition of the many failures in management have now led FAO member countries and other relevant stakeholders to broaden the approach and governance, that is, the sum of the legal, social, economic and political arrangements used to manage fisheries and aquaculture in a sustainable manner is currently seen as a necessary context for management and is becoming the main concern. Aquaculture continues to expand, while marine capture fisheries - when summed together worldwide - seem to have reached a ceiling. Reflecting the growing importance of aquaculture, The State of World Fisheries and Aquaculture ends with a discussion of the challenges that aquaculture is facing as well as of the opportunities that are open to the sector. The discussion is based on a prospective analysis of the aquaculture sector worldwide, which was undertaken by FAO in the past two years.

The 2018 edition of The State of World Fisheries and Aquaculture emphasizes the sector’s role in achieving the 2030 Agenda for Sustainable Development and the Sustainable Development Goals, and measurement of progress towards these goals. It notes the particular contributions of inland and small-scale fisheries, and highlights the importance of rights-based governance for equitable and inclusive development. As in past editions, the publication begins with a global analysis of trends in fisheries and aquaculture production, stocks, processing and use, trade and consumption, based on the latest official statistics, along with a review of the status of the world’s fishing fleets and human engagement and governance in the sector. 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.
