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.

Book Synopsis Discards in the World's Marine Fisheries by : Kieran Kelleher
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.
Book Synopsis A Global Assessment of Fisheries Bycatch and Discards by : Dayton L. Alverson
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.

Book Synopsis Encyclopedia of Energy, Natural Resource, and Environmental Economics by :
Download or read book Encyclopedia of Energy, Natural Resource, and Environmental Economics written by and published by Newnes. This book was released on 2013-03-29 with total page 1056 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every decision about energy involves its price and cost. The price of gasoline and the cost of buying from foreign producers; the price of nuclear and hydroelectricity and the costs to our ecosystems; the price of electricity from coal-fired plants and the cost to the atmosphere. Giving life to inventions, lifestyle changes, geopolitical shifts, and things in-between, energy economics is of high interest to Academia, Corporations and Governments. For economists, energy economics is one of three subdisciplines which, taken together, compose an economic approach to the exploitation and preservation of natural resources: energy economics, which focuses on energy-related subjects such as renewable energy, hydropower, nuclear power, and the political economy of energy resource economics, which covers subjects in land and water use, such as mining, fisheries, agriculture, and forests environmental economics, which takes a broader view of natural resources through economic concepts such as risk, valuation, regulation, and distribution Although the three are closely related, they are not often presented as an integrated whole. This Encyclopedia has done just that by unifying these fields into a high-quality and unique overview. The only reference work that codifies the relationships among the three subdisciplines: energy economics, resource economics and environmental economics. Understanding these relationships just became simpler! Nobel Prize Winning Editor-in-Chief (joint recipient 2007 Peace Prize), Jason Shogren, has demonstrated excellent team work again, by coordinating and steering his Editorial Board to produce a cohesive work that guides the user seamlessly through the diverse topics This work contains in equal parts information from and about business, academic, and government perspectives and is intended to serve as a tool for unifying and systematizing research and analysis in business, universities, and government
Book Synopsis Mortality of Fish Escaping Trawl Gears by : Petri Suuronen
Download or read book Mortality of Fish Escaping Trawl Gears written by Petri Suuronen and published by Food & Agriculture Org.. This book was released on 2005 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress has been made in reducing bycatch and discards through improving the selectivity of fishing gear. This publication examines the key factors affecting the stress, injury and mortality of fish arising from fishing processes, particularly when fish escape from trawl equipment. It seeks to identify improved methodological approaches and practices, and to consider the design of fishing gears and operations that reduce or eliminate such deaths, and to assess the problems associated with estimating the impact of unaccounted fish mortality.
Book Synopsis Fisheries and Aquaculture - Volume II by : Patrick Safran
Download or read book Fisheries and Aquaculture - Volume II written by Patrick Safran and published by EOLSS Publications. This book was released on 2009-10-27 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries and Aquaculture theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Fisheries are a major life support system and the main purpose of this theme on Fisheries and Aquaculture is to provide baseline information and latest knowledge at the dawn of this century to facilitate vital fisheries recovery before their irreparable collapse. This Theme on Fisheries and Aquaculture is divided into five topics. It starts with discussions on major issues and challenges in “Harvesting the Seas”, with emphasis on the role and importance of the fisheries sector and its environment, and introduces trends and perspectives in marine fisheries, including allocation of use rights, subsidies, and port management. The next two topics present an in-depth and detailed knowledge on fish and other aquatic living resources that are commercially exploited and/or farmed. The third topic on Inland Fisheries presents salmonid fish, eels, shad, whitefish and smelt, carp, perch, pike and bass, tilapia, frog, and crustaceans. The fourth topic presents a comprehensive review of trends and perspectives in Aquaculture: Principles and Prospects. The fifth topic on Economics of Fisheries and Aquaculture reviews the latest views and concepts useful to apprehend the fisheries management regime, including a comparative static economic theory and a dynamic theory of fishery, spatial bioeconomic dynamics and role of international law in the management of marine fisheries, rights-based and community fisheries management, aquaculture economics, and game theory and fisheries. These five volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

Book Synopsis A third assessment of global marine fisheries discards by : Food and Agriculture Organization of the United Nations
Download or read book A third assessment of global marine fisheries discards written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-02-19 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Saving Global Fisheries by : J. Samuel Barkin
Download or read book Saving Global Fisheries written by J. Samuel Barkin and published by MIT Press. This book was released on 2013-01-18 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: A proposal for a new global approach for fisheries focused on reducing fishing capacity and providing incentives for long-term sustainability. The Earth's oceans are overfished, despite more than fifty years of cooperation among the world's fishing nations. There are too many boats chasing too few fish. In Saving Global Fisheries, J. Samuel Barkin and Elizabeth DeSombre analyze the problem of overfishing and offer a provocative proposal for a global regulatory and policy approach. Existing patterns of international fisheries management try to limit the number of fish that can be caught while governments simultaneously subsidize increased fishing capacity, focusing on fisheries as an industry to be developed rather than on fish as a resource to be conserved. Regionally based international management means that protection in one area simply shifts fishing efforts to other species or regions. Barkin and DeSombre argue that global rather than regional regulation is necessary for successful fisheries management and emphasize the need to reduce subsidies. They propose an international system of individual transferable quotas that would give holders of permits an interest in the long-term health of fish stocks and help create a sustainable level of fishing capacity globally.
