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 Advances and best practices in bycatch reduction in tropical shrimp trawl fisheries written by Eayrs, S., Fuentevilla, C. and published by Food & Agriculture Org.. This book was released on 2021-10-25 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report describes efforts to mitigate bycatch through gear modifications and adaptations in the tropical shrimp-trawl fisheries of over 30 countries. It provides a summary of efforts by each country and then synthesizes them to identify and describe best practice. A best practice in bycatch reduction is the application or adoption of appropriate, recognized approaches to modifying fishing gear, with the objective of reducing bycatch to the greatest extent practicable. This information serves as a benchmark to identify countries that are taking appropriate steps to reduce bycatch and those that are not. It also provides context from which the outcomes of research on bycatch reduction can be evaluated and compared, including the identification of effective bycatch reduction devices, and serves to identify future research priorities. In the context of this report, best practice includes the installation and use of TEDs and BRDs that are optimally rigged and operated so as to reduce bycatch. It also includes the application of appropriate regulations to ensure effective performance, as well as the introduction of effective outreach and extension programmes to enhance and sustain best practice to reduce bycatch.
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 A Global Assessment of Fisheries Bycatch and Discards written by Dayton L. Alverson and published by Food & Agriculture Org.. This book was released on 1994 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Tropical Estuarine Fishes written by Stephen J. M. Blaber and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on the large array of tropical estuarine fishes has increased markedly in recent years and hence scientific knowledge about most aspects of these important fishes' biology and ecology is now catching up with that of their temperate equivalents. This landmark book draws together a vast wealth of information on tropical estuarine fishes and provides a vital reference point for all aspects of their study. The book's comprehensive contents include thorough coverage of the types and distribution of these fishes, their diversity and the environmental conditions and communities in which they live. Full details of their biology and ecology are an integral part of this book, as are details of these fishes' dependence on estuaries, man's interaction with the estuarine fish community and the conservation of estuarine species and the often threatened habitats upon which they depend. The author, Stephen Blaber, has a vast wealth of experience in the subject areas covered by this book and has produced a stimulating and extremely valuable volume that will be of huge importance for all those concerned with these fishes. He is based at CSIRO Marine Research, Cleveland, Queensland, Australia. Readership should include: fish biologists; fisheries scientists; aquatic scientists including those concerned with brackish, marine and freshwater environments; ecologists; environmental scientists and population biologists. Students studying for qualifications in fish biology and fisheries, particularly where there is a tropical element to their course will find this book of great value as a reference. Copies of the book should be available on the shelves of all libraries in research establishments and universities where biological sciences, fish biology, fisheries science or aquatic sciences are studied and taught.
Download or read book Overview of mitigation measures to reduce the incidental catch of vulnerable species in fisheries written by Sacchi, J. and published by Food & Agriculture Org.. This book was released on 2021-06-23 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potentially harmful contact between fisheries and marine vulnerable species represents a global conservation issue and efforts to mitigate the negative repercussions of these interactions belong in strategies for ensuring the sustainability of fisheries. This literature review offers a survey of mitigation measures and techniques that have been developed and tested around the world, aiming to address both the incidental catch of highly mobile species – specifically, cetaceans, seabirds, sharks and rays, and sea turtles – and depredation caused by dolphins. Based on research detailed in over 300 documents, including peer-reviewed publications, reports from international organizations and papers available on the internet, most of the mitigation techniques illustrated are still under development, with only a few already adopted through legislation. The selected mitigation measures are grouped by main types of fishing gear – gillnets and trammel nets, longlines and lines, trawls, purse seines, traps and pots – and further subdivided according to which of the four main groups of vulnerable species – cetaceans, seabirds, sharks and rays, or sea turtles – they are designed to protect. Preventive and curative approaches covering both technical measures (gear modifications, strategies, as well as acoustic, visual, magnetic and chemosensory deterrents) and management measures are described.
Download or read book Biodiversity Integrating Conservation and Production written by Tony Norton and published by CSIRO PUBLISHING. This book was released on 2008-09-08 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australia’s experience in community-based environmental repair is unique in the world, with no shortage of analysis by bureaucrats, academics and environmentalists. This collection of 17 case studies gives a view from ground level. It includes heroic accounts of families who changed their way of farming and their relationship to the land so significantly they found they could stop hand-feeding stock during a drought and see the bush coming back. It describes the experience with ‘bush tenders’, which were oversubscribed, as farmers competed with each other for stewardship payments to manage their grazing lands for endangered ground-nesting birds as well as beef and wool. And it tells of a group of wheat growers who plant patches of grassland for beneficial insects that save them tens of thousands of dollars a year in pesticide bills. The case studies arose from a meeting of 250 farmers, foresters and fishers from all Australian states, who met in Launceston as guests of the community group Tamar Natural Resource Management to reflect on the question: ‘Is it possible to be good environmental managers and prosper in our businesses?’ As well as tales of environmental hope, there are also messages about the limits of duty of care, the need to share the costs of achieving society’s expectations, and the possibility of learning from unlikely places. Biodiversity: Integrating Conservation and Production includes the seven ‘Tamar Principles’, distilled by the delegates from the meeting for those on the front line.

This book was released on 2012-01-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there have been notable advances in the fisheries. Progresses made in refinements of vessels, new line materials and line-handling systems, preserving the catch, the availability of oceanographic-sensor equipments and the utilization of satellite technology to locate potential fishing grounds have greatly improved the fishing power of longline vessels. Post harvest technology of fish has evolved in the last one decade to a more energy-efficient, cost-effective, and quality upgrading technology. Since fresh fish can get spoiled very quickly, the development of technology for post-harvest preservation and methodology to convert fish to value added products have also become popular in recent times. Value addition helps in getting high price for the fishery products. There is a need to develop competent human resources in the field of post harvest management of fish and production of value added products from them. It is required to inculcate vocational and entrepreneurial skills in order to widen employment opportunities, particularly among rural youth and the disadvantaged sections of the society as well as to enable self employment.

Download or read book Chondrichthyes written by Luis Fernando Rodrigues-Filho and published by BoD – Books on Demand. This book was released on 2017-12-20 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chondrichthyes are a group of cartilaginous fish, where we have sharks, rays, and chimeras as members. This group plays an important role in aquatic ecology, as they act as predators throughout the food chain (e.g., sharks). However, many populations of Chondrichthyes are threatened by several factors (increased direct fishing, high mortality rate as accompanying fauna, marine pollution, habitat destruction, etc.). These declines are evident in many parts of the world and have come to the attention of scientists, conservation organizations, the media, and the general public. Fisheries legislation regulating international fisheries markets has been amended to provide greater protection for this group along with other species of fish. However, little is known about these species, which reinforces the importance of studies in order to have a better understanding of the elasmobranch stocks, as well as to identify the influences of the anthropic action of fishing. In response to knowledge on the low sustainability of cartilaginous fish fisheries on a global scale, FAO has developed an international plan of action for the management and conservation of these fish, with the aim of developing and implementing national plans of action to ensure management and conservation of these stocks, having as main recommendation the collection of information about the Chondrichthyes, especially the sharks. Even so, this group is little known in terms of biodiversity, ecology, behavior, and a host of other characteristics relevant to this taxon, which is very worrying. Chondrichthyes - Multidisciplinary Approach attempts to portray to the readers up-to-date information on Chondrichthyes to promote an overview of the current taxon, serving as an indispensable source of access to more accurate and detailed information on shark rays and chimeras.
Download or read book Tropical Conservation written by A. Alonso Aguirre and published by Oxford University Press. This book was released on 2017 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropics and subtropics are home to about 75% of the global human population. Cultural, economic, and political circumstances vary enormously across this vast geography of some 170 countries and territories. The regions not only harbor the world's poorest countries but their human populations are growing disproportionally faster than in temperate zones. Some countries are developing rapidly -- Brazil, China, India, and Mexico being obvious examples, while others still remain in the poverty trap. This region contains an astonishing proportion of global biodiversity; some 90% of plant and animal species by some measures. Its contribution to human well-being is astounding. It was the birthplace for our species; and it hosts a myriad of plant and animal species which products feed us, keep us healthy, and supply us with a variety of material goods. The tropics and subtropics are also a natural laboratory where some of humanity's most important scientific discoveries have been made. Such biodiversity has enormous implications for research priorities, capacity building, and policy to address the challenges of conserving this region. Tropical Conservation: Perspectives on Local and Global Priorities drew the majority of its contributors from this growing pool of scientists and practitioners working in Latin America, Africa, and Asia. It introduces important conservation concepts and illustrates their application as the authors directly capture real world experiences in their home countries in preventing biodiversity loss and sustaining ecological health. Today, no part of the world can be viewed in isolation, and we further codify and integrate a range of approaches for addressing global threats to nature and environmental sustainability, including climate change and emerging diseases. Five sections structure the major themes.
