Download or read book Discards in the World s Marine Fisheries written by Kieran Kelleher and published by Food & Agriculture Org.. This book was released on 2005 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Sunken Billions Revisited written by World Bank and published by World Bank Publications. This book was released on 2017-02-10 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book A Pilot Study to Evaluate the Use of Electronic Monitoring on a Bering Sea Groundfish Factory Trawler written by Howard Ingram McElderry and published by . This book was released on 2008 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archipelago Marine Research Ltd. was contracted by the International Pacific Halibut Commission to investigate the use of video monitoring technology in the groundfish trawl catcher processor fleet operating in the Bering Sea and U.S. Exclusive Economic Zone. This pilot study involved field testing a digital video monitoring system consisting of nine closed circuit television cameras, GPS, and on-board data storage. Cameras were installed in key fish handling areas, providing a full view of trawl deck and closer views of the interior factory and discard chutes. Using the series of cameras installed throughout the factory, individually tagged halibut were tracked through the factory sorting process to discard. The tests using video monitoring equipment provided promising results for the use of this technology. The system performed reliably and provided the scientific personnel and vessel crew with a useful real-time monitoring tool. Post-cruise data analysis demonstrated that halibut were readily detectable throughout the factory. However, imagery was not suitable for making detailed assessments of catch composition. We believe that video monitoring offers opportunities to improve observer's abilities to monitor catch on factory trawlers. Further work is needed to evaluate the benefits of video monitoring in terms of the various monitoring issues in the fishery and decide on appropriate specifications for the equipment, how it should be configured, and appropriate methodology for use of video data. In particular, we highlight the need for careful consideration for the data issues surrounding the use of this technology.
Download or read book Electronic Monitoring for Control on Fishing Vessels written by A.T.M. van Helmond and published by . This book was released on 2021 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluates the potential of Electronic Monitoring (EM) to monitor compliance in the Dutch bottom trawl fishery, which, eventually, can be used as a guideline for further preparation of an EM pilot in Dutch fisheries. Within this context the feasibility of EM to monitor compliance of the landing obligation (LO) in Dutch bottom trawl fisheries is analysed considering technical, practical and financial requirements for control purposes and the ability of EM to completely document the catch, including discards, as stated on under the LO. In addition, the social aspects around the implementation of EM are described: the negative perception of EM by many fishers and the options that facilitate its uptake by the fishing industry. A detailed review of the technical standards as described by the European Fisheries Control Agency (EFCA) and comparison with EM setups used during scientific trails points out that several technical standards can be considered as control specific. Technical applications on remote access, data back- up, data storage and transfer, camera positioning system diagnostics, drafting vessel monitoring plans and data exchange formats should be considered when implementing EM for LO control purposes. The estimated total budget needed for fleetwide implementation for EM on the current Dutch beam trawler fleet, approximately 105 vessels, is estimated at 1.2 million euro to set up an EM programme and 1.9 million euro for annual running costs. The efficiency of EM to register catch very much depends on the type of fishery and catch, e.g. species and catch composition. EM preforms better when catches are processed in such a manner that it is easy to detect individual fish on video footage. This depends on the type of fisheries, e.g. hook and line fisheries, or the monitoring objectives, i.e. specimens of a particular species, are easily spotted in the catch. Results of previous studies showed that EM is less efficient in detecting smaller specimens, e.g. undersized and discarded fish. Occlusions of fish and other organic material on the sorting belt were the main reason for structural underestimation of the discarded catch. Manual review of EM video data is perceived as a highly labour intensive and time consuming task. Implementation of protocols to increase visibility of discards improves efficiency of EM, but it comes with a cost. The estimated extra time needed to conduct a protocol to better display discarded catch in front of the cameras would exceed 12 hours per fishing trip. Computer vision technology will reduce time and manual labour currently needed for EM video review and decreases the level of dependency in discard recording of fishers for control purposes. In order to successfully implement EM, it is important that the fishing industry supports and accepts the tool as beneficial. Currently there is a sense of distrust and resistance on behalf of a large part of the fishing fleet. The incentives offered for fishers to participate in previous, more scientific orientated, EM trials were direct and consisted of individual quota uplifts, direct payments, increased days at sea, access to closed areas and increased flexibility in gear choice. However, in order to roll out EM over the entire Dutch (and European) fleet, a more intrinsic motivation is required. This can be fuelled by indirect incentives, such as increased market access though eco-labelling, but also by experiencing the advantages in terms of better fishing opportunities or healthy fisheries, because, EM provides better data for improved fisheries management. A first step in creating support is to involve the fishers in the process of planning and implementation. Managers, fishers, scientists, IT specialists and other relevant parties need to discuss the concerns of the parties involved, such as privacy, data security, data ownership, and information provision. The discussions are also an opportunity to manage expectations and to help build trust and confidence. The establishment of a multi-stakeholder group including industry representatives and experts could facilitate this process. Implementation of EM on a large scale requires a substantial investment. EM generates a significant amount of (video) data, and needs an infrastructure that supports data transfer, storage, and review facilities. Development of computer vision technology to support the EM implementation process is recommended, the technology reduces time, costs and manual review needed and enhances the recording of discards under the LO.

Download or read book A Guide to Bycatch Reduction in Tropical Shrimp trawl Fisheries written by Steve Eayrs and published by Food & Agriculture Org.. This book was released on 2007 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bycatch is the unwanted or non-target part of the catch taken by fishermen. It is either discarded at sea or used for human or animal consumption. The capture of bycatch may pose a threat to species diversity and ecosystem health because this part of the catch is usually unregulated. In tropical shrimp-trawl fisheries, bycatch often consists of juvenile food-fish species and is therefore a threat to food security and sustainable fisheries production. Bycatch is a global problem that must be addressed. This Guide to Bycatch Reduction in Tropical Shrimp-Trawl Fisheries is designed for fishermen, net makers, fishing technologists and others interested in a practical guide to the design, use and operation of effective bycatch reduction devices. Fishery managers, policy-makers and legislators will find this guide useful to help develop specifications governing the design and application of these devices in a shrimptrawl fishery. The issue of bycatch is not going away and scrutiny of fishing activity is increasing. All fishermen are strongly urged to use appropriate bycatch reduction measures to help maintain the productivity of the fishery and the long term prosperity of the fishing industry. By responding appropriately, fishermen can help to protect the marine environment and assist global food security both now and in the future. Also published in French and Spanish.

Download or read book Bycatch Management and the Economics of Discarding written by Sean Pascoe and published by Food & Agriculture Org.. This book was released on 1997 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
