Download or read book Ecosystem Based Fisheries Management written by Jason Link and published by Cambridge University Press. This book was released on 2010-10-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.
Download or read book Fishery Co Management written by Robert S. Pomeroy and published by CABI. This book was released on 2005 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, there has been a shift in the governance and management of fisheries to a broaderapproach that recognizes the participation of fishers, local stewardship, and shared decision-making.Through this process, fishers are empowered to become active members of the management team,balancing rights and responsibilities, and working in partnership with government. This approach iscalled co-management.This handbook describes the process of community-based co-management from its beginning, throughimplementation, to turnover to the community. It provides ideas, methods, techniques, activities, checklists,examples, questions and indicators for the planning and implementing of a process of community-basedco-management. It focuses on small-scale fisheries (freshwater, floodplain, estuarine, or marine) indeveloping countries, but is also relevant to small-scale fisheries in developed countries and to themanagement of other coastal resources (such as coral reefs, mangroves, sea grass, and wetlands). Thishandbook will be of significant interest to resource managers, practitioners, academics and students ofsmall-scale fisheries.
Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

Download or read book Voluntary Guidelines for Securing Sustainable Small Scale Fisheries in the Context of Food Security and Poverty Eradication written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-16 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines) represent the first ever international instrument dedicated to small-scale fisheries. They represent a global consensus on principles and guidance for small-scale fisheries governance and development. They were developed for small-scale fisheries in close collaboration with representatives of small-scale fisheries organizations in a participatory process between 2011-13, involving over 4000 stakeholders; facilitated by FAO, based on a mandate by COFI. They are directed at all those involved in the sector and intend to guide and encourage governments, fishing communities and other stakeholders to work together and ensure secure and sustainable small-scale fisheries for the benefit of small-scale fishers, fish workers and their communities as well as for society at large.
Download or read book Improving Fish Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-02-27 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.
Download or read book Marine Protected Areas written by National Research Council and published by National Academies Press. This book was released on 2001-06-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated for special protection to enhance the management of marine resources. Therefore, there is an urgent need to evaluate how MPAs can be employed in the United States and internationally as tools to support specific conservation needs of marine and coastal waters. Marine Protected Areas compares conventional management of marine resources with proposals to augment these management strategies with a system of protected areas. The volume argues that implementation of MPAs should be incremental and adaptive, through the design of areas not only to conserve resources, but also to help us learn how to manage marine species more effectively.
Download or read book Conservation of Exploited Species written by John D. Reynolds and published by Cambridge University Press. This book was released on 2001-10-18 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of wildlife for food and other human needs poses one of the greatest threats to the conservation of biodiversity. Wildlife exploitation is also critically important to many people from a variety of cultures for subsistence and commerce. This book brings together international experts to examine interactions between the biology of wildlife and the divergent goals of people involved in hunting, fishing, gathering and culling wildlife. Reviews of theory show how sustainable exploitation is tied to the study of population dynamics, with direct links to reproductive rates, life histories, behaviour and ecology. As such theory is rarely put into practice to achieve sustainable use and effective conservation, Conservation of Exploited Species explores the many reasons for this failure and considers remedies to tackle them, including scientific issues such as how to incorporate uncertainty into estimations, as well as social and political problems that stem from conflicting goals in exploitation.

Download or read book A Review of Length based Approaches to Assessing Fish Stocks written by J. A. Gulland and published by Food & Agriculture Org.. This book was released on 1992 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document reviews the several fish stock assessment methods based on length-frequency analysis. Emphasis is placed on sampling and collection of length-frequency data, to the estimation of population parameters such as growth, mortality and recruitment and the estimation of catch selectivity. Attention is given to the conversion of length to age using age-length keys, slicing length-frequency composition, and using modes. It reviews long-and short-term effects of changes in selection and fishing mortality, and discusses methods for long-term assessments and for short-term projections. The manual gives several examples of the most common methods used and stresses the advantages of using personal computers and the most recent software for data processing and analysis.
Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

This book was released on 2017-08-24 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service (NMFS) of the National Oceanic and Atmospheric Administration (NOAA) is responsible for collecting information on marine recreational angling. It does so principally through the Marine Recreational Information Program (MRIP), a survey program that consists of an in-person survey at fishing access sites and a mail survey, in addition to other complementary or alternative surveys. Data collected from anglers through MRIP supply fisheries managers with essential information for assessing fish stocks. In 2006, the National Research Council provided an evaluation of MRIP's predecessor, the Marine Recreational Fisheries Statistics Survey (MRFSS). That review, Review of Recreational Fisheries Survey Methods, presented conclusions and recommendations in six categories: sampling issues; statistical estimation issues; human dimensions; program management and support; communication and outreach; and general recommendations. After spending nearly a decade addressing the recommendations, NMFS requested another evaluation of its modified survey program (MRIP). This report, the result of that evaluation, serves as a 10-year progress report. It recognizes the progress that NMFS has made, including major improvements in the statistical soundness of its survey designs, and also highlights some remaining challenges and provides recommendations for addressing them.

Download or read book Mismanagement of Marine Fisheries written by Alan Longhurst and published by Cambridge University Press. This book was released on 2010-04-22 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Longhurst examines the proposition, central to fisheries science, that a fishery creates its own natural resource by the compensatory growth it induces in the fish, and that this is sustainable. His novel analysis of the reproductive ecology of bony fish of cooler seas offers some support for this, but a review of fisheries past and present confirms that sustainability is rarely achieved. The relatively open structure and strong variability of marine ecosystems is discussed in relation to the reliability of resources used by the industrial-level fishing that became globalised during the 20th century. This was associated with an extraordinary lack of regulation in most seas, and a widespread avoidance of regulation where it did exist. Sustained fisheries can only be expected where social conditions permit strict regulation and where politicians have no personal interest in outcomes despite current enthusiasm for ecosystem-based approaches or for transferable property rights.
