This publication gives an updated review of the quantity of discards in the world's marine fisheries, using information from a broad range of fisheries in all continents. A number of policy issues are discussed including a 'no discards' approach to fisheries management, the need for balance between bycatch reduction and bycatch utilisation initiatives, and concerns arising from incidental catches of marine mammals, birds and reptiles. The report also highlights the need for more robust methods of estimating discards, and the development of bycatch management plans.

This third update of FAO’s global discard estimate adopted the ‘fishery-by-fishery’ approach employed in the second discards assessment published in 2005. The update included publicly available discard data in the last 20 years to establish a baseline of a time series of global marine fisheries discards. This is essential for monitoring the status and trends of discard management, which is the first step of the ecosystem approach to fisheries management cycle. In addition, the study developed a new fisheries data table incorporating landings data from the FAO Global Capture Production dataset (FishStat J) from 2010 to 2014, which allocated the landings to over 2 000 fisheries worldwide. The current study estimated that the annual discards from global marine capture fisheries between 2010 and 2014 was 9.1 million tonnes (95% CI: 6.7 – 16.1 million tonnes). About 46 percent (4.2 million tonnes) of total annual discards were from bottom trawls that included otter trawls, shrimp trawls, pair bottom trawls, twin otter trawls and beam trawls. The study included a synthesis of estimates of bycatch and discards of endangered, threatened and protected (ETP) species. Substantial advances have been made in quantifying fisheries interactions with such species so as to make informed decisions on their protection. However, many challenges remain, especially for small-scale fisheries. The development of standardized data collection techniques, risk-based sampling and sharing of data across agencies and regions will help to identify management priorities and allow implementation and enforcement of mitigation measures. A review of previous research showed that discard practices were often related to a wide range of factors, so it is difficult to assess the effectiveness of fishery management actions on the amount and practice of discards. Many regulations are inconsistently enforced, and their implementation is often less strict than intended. Piecemeal approaches in many bycatch and discards management measures can result in unintended cross-taxa conflicts, where regulations designed to reduce bycatch and/or discards of one species or species group may increase bycatch and/or discards of another. Examination of approaches to accounting for and mitigating against pre-catch, post-capture and ghost fishing mortalities demonstrates that an understanding of the relative importance of factors affecting indirect fishing mortality is necessary for estimating total fishing-induced mortality and for designing and implementing mitigation measures.

The increase in commercial fisheries production over the last 50 years has been accompanied by an increase in the level of incidental catch and discarding of a number of species. Approximately one quarter of the marine commercial catch destined for human consumption is discarded at sea. This has raised the concern of a number of groups in society, including environmentalists, humanitarians and fishers themselves. In this paper, the economic incentives to discard fish are examined. The effects of different managemenet policies on these incentives are also investigated. The concept of an optimal level of discarding is discussed taking into account the externalities that can be created by discarding. Finally, the effectiveness of various measures to reduce the level of discarding is reviewed. these including technical, administrative and economic measures.

The project “Sustainable management of bycatch in Latin America and Caribbean trawl fisheries” was financed by GEF, implemented and executed by FAO. With an overall evaluation rating of Highly Satisfactory, the assessment has identified notable results in strengthening regional collaboration, improving legal frameworks and co-management mechanisms; successful trials of bycatch reduction devices; and building capacity, including of women. The global environment objective (GEO) and the project development objective (PDO) were partially achieved, reflecting the over-ambitiousness of the design. However, the enabling environment created, and the transformational results will contribute towards achievement of these objectives in the long-term. Strategic partnerships and the high level of stakeholder engagement including the private sector contributed to successful delivery. Recommendations include actions to be taken by the project partners and stakeholders to build on the project results to achieve sustainable, long-term impact; thematic areas for follow-up projects; more realistic project objectives and improvement in institutional arrangements and administrative procedures for future projects; sustaining partnerships; enhancing livelihoods and empowerment of women fish workers; and better communication and knowledge management.

The authors estimate that between 17.9 and 39.5 million tons (average 27.0 million) of fish are discarded each year in commercial fisheries. These estimates are based on a review of over 800 papers. The highest quantities of discards are from the Northwest Pacific while tropical shrimp trawl fisheries generate a higher proportion of discards than any other fishery type, accounting for one third of the global total. Of four major gear groups, shrimp trawls stand alone at the top of the list; bottom trawls, long-lines and pot fisheries come next. The third group consists of Japanese high-seas drift net fisheries, Danish seines and purse seines for capelin. Relatively low levels result from pelagic trawls, small pelagic purse seines and some of high seas drift nets. The authors point to inadequate data to determine the biological, ecological, economic and cultural impacts of discards although economic losses run to billions of dollars. However, it appears most likely that socio-cultural attitudes towards marine resources will guide international discard policies. Techniques to reduce bycatch levels including traditional net selectivity, fishing gear development and time/area restrictions, are discussed. Effort reduction, incentive programmes and individual transferable quotas (that make the vessel responsible for bycatch reduction) are seen as promising avenues for the future. However, quick solutions to the problem are unlikely and much more information is required. The publication includes a diskette with the complete Bycatch Database, which was compiled for the study, and a summary of it.

The objective of this manual is to provide a working document for Contracting Parties (or “Member”) and Cooperating Non-contracting Parties (CPCs) to use in the implementation of the IOTC Resolutions. The content is divided into two chapters. The first chapter provides a broad overview of the international regime within which the Indian Ocean Tuna Commission has evolved, then examines the role of specific key international legal instruments (conventions and agreements) related to Indian Ocean tuna fisheries. It describes the roles of Regional Fisheries Management Organisations (RFMOs) and Regional Fisheries Advisory Bodies (RFABs), and explains what the IOTC is, how it is supposed to work, who drives it and what results are expected of it. The second chapter summarises the principles and measures provided by international instruments that guide fisheries management. It then describes the fisheries management tools used by IOTC from the perspectives of coastal States, flag States, port States and market States. This manual should be viewed as a living document that can be revised and improved by all parties as experience is expanded in the implementation of the IOTC Conservation and Management Measures.

The growing quantity of plastic waste in the marine environment including abandoned, lost or otherwise discarded fishing gear (ALDFG) is a global problem. A particular feature of ALDFG is the potential of some gears to carry on fishing for many months or even years. The study examines legal responses to ALDFG in the context of marine fisheries. After discussing the nature of the problem of ALDFG and some of the reasons why fishing gear is abandoned, lost, or otherwise discarded, the study examines the response of the international community to ALDFG. A key finding is that ALDFG is at the same time, a fishing issue, a navigation problem (of vessel source pollution) and an environmental problem with the resulting involvement of FAO, IMO and UNEP as well as the UN General Assembly. After examining potential legal approaches to the problem, the study then describes the basic legal and institutional arrangements in four case study jurisdictions that have adopted legal measures to address ALDFG, namely Australia, the European Union and its Member States, Norway and the USA finding once again the tripartite responsibility of fisheries, navigation and environment ministries/agencies. The inter-sectoral nature of ALDFG suggests the need for a collaborative and coordinated approach. While not all of the case study jurisdictions make use of all ten of the individual legal measures identified, the case studies also clearly show that ALDFG is a problem that is susceptible to a legal response at the national or regional level including through the use of extended producer responsibility schemes, various reporting requirements and gear standards. Legal tools to address the problem of ALDFG clearly exist. The extent to which some, or all, of them are necessary or appropriate in a given context at national, regional or global level is not ultimately a legal question but a political one.
