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.

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 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 Sharing the Fish written by National Research Council and published by National Academies Press. This book was released on 1999-06-09 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most U.S. fish stocks are fully or over-exploited, and harvesting in many fisheries far exceeds sustainable levels. The individual fishing quota (IFQ) is a relatively new instrument under which harvesting privileges are allocated to individual fishermenâ€"innovative yet controversial for its feared effect on fishing communities and individual fishermen. Based on testimony from fishermen, regulators, environmentalists, and others, Sharing the Fish explores how IFQs might address the serious social, economic, and biologic issues raised by depleted fish stocks. In their approach to a national policy on IFQs, the panel makes direct recommendations to Congress, the Secretary of Commerce, the National Marine Fisheries Service, regional fishery management councils, state authorities, and others. This book provides definitions and examples, reviews legislation and regulations, and includes lessons learned from fisheries on the U.S. East Coast and in Alaska, and in Iceland, New Zealand, and other nations. The committee discusses the public trust doctrine, management of common-pool resources, alternative and complementary approaches to the IFQ, and more. Sharing the Fish provides straightforward answers that will be important to fishery policymakers and regulators, natural resource economists, fishery managers, environmental advocates, and concerned fishermen and their communities.

Available in PDF, EPUB and Kindle. Book excerpt: 'The Sunken Billions: The Economic Justification for Fisheries Reform' shows the difference between the potential and actual net economic benefits from marine fisheries is about $50 billion per year, or some $2 trillion over the last three decades. If fish stocks were rebuilt, the current marine catch could be achieved with approximately half the current global fishing effort. This illustrates the massive overcapacity of the global fleet. The excess competition for the limited fish resources results in declining productivity, economic inefficiency, and depressed fisher incomes. The focus on the deteriorating biological health of world fisheries has tended to obscure their equally critical economic health. Achieving sustainable fisheries presents challenges not only of biology and ecology, but also of managing political and economic processes and replacing pernicious incentives with those that foster improved governance and responsible stewardship. Improved governance of marine fisheries could regain a substantial part of this annual economic loss and contribute to economic growth. Fisheries governance reform is a long-term process requiring political will and consensus vision, built through broad stakeholder dialogue. Reforms will require investment in good governance, including strengthening marine tenure systems and reducing illegal fishing and harmful subsidies. Realizing the potential economic benefits of fisheries means reducing fishing effort and capacity. To offset the associated social adjustment costs, successful reforms should provide for social safety nets and alternative economic opportunities for affected communities.

Download or read book Reinventing Fisheries Management written by T.J. Pitcher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Judged by a dismaying track record and a consequent downturn in the reputation of fisheries scientists, fisheries management is certainly a candidate for calls for reinvention, with many of the world leaders in this area holding the view that no fishery has ever been properly understood or managed. With fisheries science in a state of flux, this extremely important book seeks a new paradigm that will place this flux of ideas in perspective and help us to choose those that will make fisheries management work. The book was planned at a symposium of over 100 fishery researchers at the Fisheries Centre, University of British Columbia, Vancouver, Canada and is organized into five parts: Why does Fisheries Science Need Reinventing?; New Policies; The Role of the Social Sciences; Ecology; Modelling. Carefully integrated and edited by three of the world's leading fishery scientists, this stimulating book should find a place on the shelves of all fishery scientists throughout the world. It will be an invaluable reference source to those studying fish biology, fisheries and oceanography and all those involved in fisheries policy decisions in government and university research establishments.

Available in PDF, EPUB and Kindle. Book excerpt: Most of the major impacts of fishing on the ecosystems recorded around the world occur in the Mediterranean. This variety of interactions is due to four main interrelated factors: the wide range of fishing gear and practices; very intensive fishing; a high diversity of exploited habitats, ranging from shallow water to the deep-sea and oceanic domain; and high biological diversity.
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.
