Performance Assessment Of Bycatch And Discards Governance By Regional Fisheries Management Organizations

Performance assessment of bycatch and discards governance by regional fisheries management organizations

A third assessment of global marine fisheries discards

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.

Conserving Biodiversity in Areas beyond National Jurisdiction

Since 2006 the United Nations General Assembly (UNGA) has been discussing the question of the conservation and sustainable use of biodiversity in areas beyond national jurisdiction. Following the issues raised by the Ad Hoc Working Group (2006 – 2015) and the Preparatory Commission (2016 – 2017) in 2017 the UNGA agreed to convene an intergovernmental conference to discuss these issues. Conserving Biodiversity in Areas beyond National Jurisdiction, edited by David Freestone, brings together a collection of essays covering some of the key issues involved in these debates. The essays are contributed by a number of distinguished scholars and practitioners – many of whom are involved in the UNGA negotiations – and are a useful reference for actors involved in the negotiations as well as for practitioners, scholars, and students following the process.
