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.

Available in PDF, EPUB and Kindle. Book excerpt: BEHAVIOR OF MARINE FISHES BEHAVIOR OF MARINE FISHES: Capture Processes and Conservation Challenges Understanding fish behavior in relation to capture processes in marine fisheries is of fundamental importance to reducing bycatch and discards, and to enhancing marine fisheries conservation efforts. A thorough understanding of this allows commercial fishers to more effectively capture target species while reducing the catch of unwanted species. Behavior of Marine Fishes: Capture Processes and Conservation Challenges provides the reader with principles, patterns, and characteristics on fish behavior and fish capture processes using several types of important commercial fishing gears. The book also highlights conservation challenges facing the marine capture fisheries in efforts to maintain sustainable use of marine resources and to reduce negative impacts to the marine ecosystem. This volume, with contributions from leading applied fish behaviorists and fishing gear technologists from around the world, will be a valuable reference for researchers, fishing gear technologists, fisheries managers, students, and conservationists. SPECIAL FEATURES: Synthesis of current research and valuable knowledge that will help reduce bycatch and discards in commercial fisheries Review of basic fish behavioral principles and patterns and their relation to capture methods and conservation efforts Contributions from leading international applied fish behaviorists and fishing gear technologists

Available in PDF, EPUB and Kindle. Book excerpt: There are many conferences, workshops and meetings annually around the world, each emphasizing a specialty area for scientific exploration and research. Yet in very few instances, if at all, do the multidisciplinary aspects of science get presented so one may see the diversity of dependencies these seemingly disparate disciplines actually have. The Explorers Club and the U. S. National Park Service collaborated to make a first attempt at what will continue to be an "ocean pulse'" effort; conferences combining the aquaculture sciences; the search for underwater antiquities and the marinelbio-technologies utilized to explore these areas. The purpose has been to bring together not just academicians to talk about their finding in the field or the laboratory, but to provide a forum for the practical applications of "technology" to expanding our worlds fisheries as well as to continue to explore our world's oceans; the earth's truly last frontier. After everything is said and done, we still know precious little about our ocean environments. Their influences on our lives are monumental and yet we continue to be very parochial and conservative in our dedication to exploring their depths and resources. We feel confident that this initial effort by our respective groups to awaken a realization in the public and private sectors of the need for a cross-disciplinary approach to scientific research in the marine environment, is a necessity as we approach the 21 st century.

Download or read book King Crabs of the World written by Bradley G. Stevens and published by CRC Press. This book was released on 2014-03-18 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: With species existing in all subpolar seas, king crabs are one of the most valuable seafoods. Major fluctuations in their abundance have stimulated a flurry of research and a rapid expansion of the scientific literature in the last decade. King Crabs of the World: Biology and Fisheries Management consolidates extensive knowledge on the biology, systematics, anatomy, life history, and fisheries of king crabs and presents it in a single volume. This book is the first comprehensive scientific reference devoted to the biology and fisheries of king crabs. The first part of the book describes king crabs and their place in the world, covering geographic distribution, depth and temperature ranges, and maps of known habitats. Chapters examine phylogenetic relationships, evolutionary history and phylogeography, internal and external anatomy of king crabs, and the history of North Pacific fisheries. There is also a chapter that presents a comprehensive overview of diseases and other anomalies of king crabs. The second part of the book describes the life history and biology of various king crab species, including embryonic development and environmental factors, the development and biology of larvae, the ecology and biology of juvenile stages, reproductive strategies of fished species, and the growth and feeding of king crabs and their ecological impacts. The third part of the book discusses human and environmental interactions with king crabs through fisheries, management, and ecosystems. Topics include the impacts of fishing—bycatch, handling, and discard mortality—king crab aquaculture and stock enhancement, and king crabs from various regions such as Southern Hemisphere waters, the Barents Sea, and Alaska. A chapter synthesizing various aspects of king crab biology provides an ecosystem-scale perspective and the final chapter presents the author’s outlook on the future of king crab research and populations.
Download or read book Challenges and Opportunities for the EU Common Fisheries Policy Application in the Mediterranean and Black Sea written by Simone Libralato and published by Frontiers Media SA. This book was released on 2019-01-11 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of the Common Fisheries Policy (CFP) in the Mediterranean and Black Sea faces several challenges also because of large ecological, economic, political and institutional differences across the basin. The challenge of CFP application is exacerbated by the legal/administrative situation, with large areas outside national/EU jurisdictions, by the different development of fisheries that result in fleet capacities highly different on opposite shores of some sub-basins, as well as by uneven monitoring and data availability across the basins that result in situations that hamper sustainable management. This book collates analyses related to the application of the principles included in the CFP in Mediterranean and Black Sea, including assessments of current status, scenario analyses, visions of best solutions, evaluation of critical hot spots and effects of regionalization of fisheries management. The eBook tackles from local to transboundary issues and solutions and provides a broad vision of problems together with important practical solutions for CFP application in the Mediterranean and Black Sea.

Available in PDF, EPUB and Kindle. Book excerpt: In 1989 we were asked by Dr Vidar Wespestad (National Oceanographic and Atmospheric Administration. National Marine Fisheries Service. Alaska Fisheries Science Center. Seattle. USA) to prepare and convene a session at the 1992 World Fisheries Congress in Athens. Greece on computer appli cations in fisheries. We agreed that the idea was a good one and the computer session turned out to be very successful. The computer session was organized in three parts: training classes. informal demonstrations accompanied by posters. and oral presentations of scientific papers. We were both amazed by the high level of interest and the high quality of contributions presented at the paper session. Returning from the World Fisheries Congress. we suggested to the International Council for the Exploration of the Sea (ICES) in Copenhagen to hold a theme session on the topic 'Computers in Fisheries Research' at their statutory meeting the fol lowing year in Dublin. Ireland. The proposal was very positively received by ICES and we began organizing this new meeting with Dr John Ramster of the Ministry of Agriculture. Fisheries and Food. Fisheries Laboratory. Lowestoft. England. Based on our experience with the World Fisheries Congress. we expected a maximum of 15 titles would be submitted to the ICES theme session. Accordingly. the ICES symposium was originally allo cated one half-day time slot. The response we received from the call for papers. however. exceeded our most optimistic expectations. A total of 62 abstracts were submitted. Consequently.
