Available in PDF, EPUB and Kindle. Book excerpt: In the last decades, the human harvesting of marine resources became more efficient as the understanding of the habits and behaviours of the various species available in the sea gradually increased. Technologies naturally developed over time and fishing systems became more sophisticated and increasingly adapted to catch the most desirable species and sizes. This evolution is still in progress and technological development goes on especially in the Mediterranean area, where small and relatively old fishing vessels are traditionally used. These technical advances in fishing gears have generally led to more efficient fishing operations and improved access to resources and fishing grounds. On the other hand, general awareness on the environmental problems due to the exploitation of fisheries resources has also increased. Therefore, in order to preserve fishery resources and marine environments, fishing gears and their impacts need to be further investigated and less impacting techniques should be developed. In this regard, fishing technologists are responsible to provide fishery managers as well as fishermen and stakeholders, with useful advice and technical solutions for mitigating adverse impacts of fishing gears. By taking these problems into account, the book contents are based on the requirements of ecosystem-approach to fisheries management. The Code of Conduct for Responsible Fisheries of the FAO (1995) encouraged the use of selective, environmentally safe and cost effective gear and techniques. Thus the book aims at providing information on sustainable fishing technologies, and transfers the expertise on fishing technology to Mediterranean fisheries scientists and end-users such as fisheries managers, administrators, controllers etc. This book is structured to provide information on fishing gear technology, selectivity, bycatch-impact reduction and fishing vessel technology, with particular attention to the Mediterranean context. The information included might be used to learn how to assess the impacts and selectivity of different fishing gears and find technical solutions to mitigate these impacts and to address scientific studies. Furthermore, advices on the properties of fishing vessels affecting energy efficiency have been also considered in order to address possible technical changes to the currents boats. Finally the contents of this book might be considered as a useful tool when preparing management measures as well as for the establishment, enforcement or improvement of fishing rules.

This book was released on 2022-01-18 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: FAO has promoted the ecosystem approach to fisheries (EAF) as an appropriate framework for the sustainable development and management of fisheries worldwide. With a view to contribute to the identification of lessons and good practices for EAF implementation, this publication documents nine case studies that attempted to put into practice some of the key principles and tools of the approach in the Mediterranean Sea. The case studies were selected to cover a broad range of contexts including smallscale and industrial fisheries operating at local, national and sub-regional scales. It was not within the scope of the publication to evaluate the level of implementation of the ecosystem approach. A specific tool for monitoring implementation is proposed and exemplified. Case studies were analysed with a view to draw preliminary lessons regarding the enabling factors that facilitated the progress made as well as the challenges faced in the transition towards EAF-based management systems. Attention is drawn to key enabling conditions such as favourable policies, legislation and regulatory frameworks, the existence of regional mechanisms for cooperation, favourable market dynamics and social processes, and the relatively low complexity of the fishery systems analysed. A set of factors emerged that contributed to progress during implementation, such as the clear definition of fishing rights, the enhancement of mechanisms for compliance, scientific monitoring and adaptation of management measures, as well as the explicit consideration of biological and socioeconomic aspects in management actions. Further progress in the transition towards sustainable management systems is hampered by external and internal factors. External factors are related, for instance, to environmental changes, the poor regulation and control of competing sectors, consumer behaviour and the governance environment. Issues such as stakeholder representation, knowledge gaps and the availability of sustainable sources of funding are among common internal factors. The authors also discuss how slow progress in the implementation of management plans can generate discredit with the institutions and add additional challenges for any future initiatives to engage stakeholders in participatory management. The case-based results and lessons of how the ecosystem approach to fisheries was considered, developed and implemented in the fisheries discussed in this publication not only contribute to the documentation of current practices in the Mediterranean but may also guide future attempts to further develop the field.

This book was released on 2020-12-14 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third edition of the State of Mediterranean and Black Sea Fisheries provides a comprehensive overview of the status of fisheries in the region, looking at their main features and trends, in order to better inform their management and better examine current and future challenges that they will face in the near future. The aim of this report is to produce a document that could provide useful analysis and direction for decision-making and future action. In this respect, this publication also represents a convenient source of information for the FAO Committee on Fisheries and offers a practical complement to the data provided in the State of World Fisheries and Aquaculture published by the FAO Fisheries and Aquaculture Department. This volume includes seven chapters divided into two sections: a first part on the status and trends of different aspects of Mediterranean and Black Sea fisheries, including fleet, catches, socio-economic variables and bycatch, and a second part that focuses on the management of Mediterranean and Black Sea fisheries, including an overview on small-scale fisheries. This report is based to a large extent on the most up-to-date data available submitted by GFCM contracting and cooperating non-contracting parties, including information on stock status, national catches, fleet and socio-economic information up to 2018. It is also complemented with information from other sources.
Download or read book Non indigenous species in the Mediterranean and the Black Sea written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-07-29 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have seen significant changes in the biota of the Mediterranean and the Black Sea due to the introduction of non-indigenous species. Reliable scientific data on the dynamics of their distribution and abundance are essential to understand their ecological and economic effects. This review – in addition to providing images and descriptions of relevant species to aid in identification – presents a unique historical and regional perspective on these species’ impacts, based on many years’ worth of research. The Black Sea’s primary invaders come from the Mediterranean. Species like the comb jelly Mnemiopsis leidyi have caused major declines in biodiversity in the region by crippling key segments of the food chain. Similar results have been noted in the Marmara Sea, a crucial water exchange point located between the Aegean Sea and the Black Sea. Infiltration into the Mediterranean comes from both the east and west – with Lessepsian species passing through the Suez Canal and fish and invertebrate species originating from the Atlantic expanding their ranges. As of the publication of this review, over 900 non-indigenous species have been reported in the Mediterranean and almost 300 in the Black Sea, with these numbers expected to rise in the future. Numerous Lessepsian fishes are commercially relevant and have been absorbed into local markets, particularly in the eastern Mediterranean region. While these species are targeted through various fishing techniques, many others are simply discarded due to a lack of value and there are even some, such as lionfishes, pufferfishes and several species of jellyfishes, that present immediate dangers to human health. Stewardship of native species, regional cooperation on the enforcement of legal measures, increased public awareness and the creation of marine protected areas are thus essential to minimize and reduce the impacts of non-indigenous species both in the Mediterranean and the Black Sea.

Download or read book Effects of Riverine Inputs on Coastal Ecosystems and Fisheries Resources written by and published by Food & Agriculture Org.. This book was released on 1995 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five chapters are presented which address a number of aspects of riverine and runoff effects on coastal marine systems. Examples are presented and documented in which the apparent effects of runnoff-related nutrient enrichment and consequent eutrophication have been important. Various other aspects, such as sedimentation, etc. are explored. The purpose is to advance the scientific, policy, and political dialogue on issues related to utilization and protection of coastal marine ecosystems. The "Marine Catchment Basin" or "MCB" appears to be the logical scale of policy and management interest wherever terrestrial runoff has substantial impacts on a marine system. The MCB expands the "marine ecosystem" concept to include not only the marine aquatic system, but also the adjacent land areas that drain into it. The MCB concept has been identified primarily with semi-enclosed seas, where effects have been particularly dramatic and where the "catchment basin" retains an easily visualized geological context. However, even along open ocean coasts, hydrodynamic processes act to retain coherent masses of water, together with their contained organisms and materials, against the coast. Thus open coastal areas may exhibit MCB features similar to those of enclosed or semi-enclosed basins

This book was released on 2013-11-11 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers presented at a NATO Advanced Research Institute on "Mediterranean Marine Ecosystems", held at Heraklion-Crete, Greece, from September 23-27, 1983. A workshop rather than a conference, it was sponsored by the Eco-Sciences Special Programme Panel, in cooperation with the Marine Science Panel. The third of its kind, it was scheduled in the framework of a project on a multidisciplinary integrated approach to the study of the Mediterranean. This Sea and the surrounding land was not only the cradle of many civilizations but is, up to the present time, one of the major world areas of marine traffic, communication and exchanges, fisheries and aquacultures, inshore human activities and ••• pollu tion. To a certain degree it constitutes a gigantic natural labo ratory, where the fate of threatened aquatic and terrestrial eco systems including the human one, is tested. The Mediterranean Sea, with its geological history and present day geographic, hydrological and climatic conditions is believed to form an ecological entity. Important exchanges and mutual influences take place with the surrounding land area and the water masses, naturally (Atlantic, Black Sea) or artificially (Red Sea), connected to the Mediterranean. Therefore, a better and in-depth knowledge of the various ecosystems, benthic, planktonic and nektonic, neritic or pelagic, in the Western or the Eastern Basin seems to be a pre requisite to any action in preserving, upgrading and managing the natural resources of the area.
Download or read book Management of Marine Protected Areas written by Paul D. Goriup and published by John Wiley & Sons. This book was released on 2017-01-17 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the health of the world’s oceans threatened as never before, it is becoming increasingly apparent that Marine Protected Areas (MPAs) play a vitally important role in protecting marine and coastal habitats. Management of Marine Protected Areas: A Network Perspective draws on the results of a major EU-sponsored research project related to the establishment of networks of MPAs in the Mediterranean and Black Seas that transpired from February 2011 to January 2016. Featuring contributions by leading university- and national research institute-based scientists, chapters utilize the latest research data and developments in marine conservation policy to explore issues related to ways in which networks of MPAs may amplify the effectiveness and conservation benefits of individual areas within them. Topics addressed include the broader socio-economic impacts of MPAs in the Mediterranean and Black Seas; the use of Marine Spatial Planning (MSP) to resolve conflicts between marine resource use and protection; special protection measures under the EU’s Marine Strategy Framework Directive (MSFD); ecological value assessments in the Black Sea; the Ecosystem Approach (EA) for managing marine ecosystems; MPAs along Turkey’s Black Sea coast; MPAs and offshore wind farms; and managing and monitoring MPA networks within and between the Black and Mediterranean Seas. Timely and important, Management of Marine Protected Areas: A Network Perspective offers invaluable insights into the role of MPAs in preserving the welfare and long-term viability of our world’s oceans.

Download or read book The Tragedy of the Commodity written by Stefano B. Longo and published by Rutgers University Press. This book was released on 2015-06-25 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2017 Paul Sweezy Marxist Sociology Book Award from the American Sociological Association Although humans have long depended on oceans and aquatic ecosystems for sustenance and trade, only recently has human influence on these resources dramatically increased, transforming and undermining oceanic environments throughout the world. Marine ecosystems are in a crisis that is global in scope, rapid in pace, and colossal in scale. In The Tragedy of the Commodity, sociologists Stefano B. Longo, Rebecca Clausen, and Brett Clark explore the role human influence plays in this crisis, highlighting the social and economic forces that are at the heart of this looming ecological problem. In a critique of the classic theory “the tragedy of the commons” by ecologist Garrett Hardin, the authors move beyond simplistic explanations—such as unrestrained self-interest or population growth—to argue that it is the commodification of aquatic resources that leads to the depletion of fisheries and the development of environmentally suspect means of aquaculture. To illustrate this argument, the book features two fascinating case studies—the thousand-year history of the bluefin tuna fishery in the Mediterranean and the massive Pacific salmon fishery. Longo, Clausen, and Clark describe how new fishing technologies, transformations in ships and storage capacities, and the expansion of seafood markets combined to alter radically and permanently these crucial ecosystems. In doing so, the authors underscore how the particular organization of social production contributes to ecological degradation and an increase in the pressures placed upon the ocean. The authors highlight the historical, political, economic, and cultural forces that shape how we interact with the larger biophysical world. A path-breaking analysis of overfishing, The Tragedy of the Commodity yields insight into issues such as deforestation, biodiversity loss, pollution, and climate change.
