Book Synopsis The State of Mediterranean and Black Sea Fisheries 2020 by : Food and Agriculture Organization of the United Nations
Download or read book The State of Mediterranean and Black Sea Fisheries 2020 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. 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.
Book Synopsis Effects of Trawling and Dredging on Seafloor Habitat by : National Research Council
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.
Book Synopsis Protected Area Management by : Barbara Sladonja
Download or read book Protected Area Management written by Barbara Sladonja and published by BoD – Books on Demand. This book was released on 2012-08-08 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protected areas are at the base of the most national and international conservation strategies. Due to the many unpredictable elements in ecology matters, each protected area requires a case-specific set of guidelines but a common issue is how to cope with human interaction. The management of protected areas is replete with challenges and the only way to gain understanding and achieve greater management possibilities is to exchange experiences and knowledge. Environmental managers are aware of that and together with scientists are looking for more modern and better solutions, both with respect to natural resources and human interactions in many issues regarding nature protection. This publication presents reviews and research results on protected areas management, as well as 12 case studies derived from around the world with the aim of improving management effectiveness of the protected areas.
