Available in PDF, EPUB and Kindle. Book excerpt: This report documents the methods and results of the 2009 Petrel Bank pot (trap) survey on the distribution and relative abundance of red king crabs Paralithodes camtschaticus in the central Aleutian Islands waters of the Petrel Bank area. The primary purposes of this survey were to provide information needed by fishery managers to consider a fishery opening in the 2010/11 season and to address the need discussed by the North Pacific Fishery Management Council Crab Plan Team (CPT) during their September 2008 meeting for stock assessment data from the Adak red king crab stock. The Alaska Department of Fish and Game (ADF&G) conducted the survey aboard the chartered F/V Arctic Fury, a 44.2-m commercial crab-pot-fishing vessel from November 6 to December 5, 2009. Results on the catch and sex-size composition of only the red king crabs encountered during the survey are presented. Most red king crabs captured during the survey occurred in a limited portion of the surveyed area and were predominately larger, matured-sized crabs. Size distribution of captured males provided no expectations for near-term recruitment of legal males. In comparison to results from the same stations fished during the 2006 ADF&G Petrel Bank pot survey, the catch of red king crabs during the 2009 survey occurred in a more limited area and the catch of legal males was lower.

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.

Book excerpt: Fishes of the Salish Sea is the definitive guide to the identification and history of the marine and anadromous fishes of Puget Sound and the Straits of Georgia and Juan de Fuca. This comprehensive three-volume set, featuring striking illustrations of the Salish Sea's 260 fish species by noted illustrator Joseph Tomelleri, details the ecology and life history of each species and recounts the region's rich heritage of marine research and exploration. Beginning with jawless hagfishes and lampreys and ending with the distinctive Ocean Sunfish, leading scientists Theodore Wells Pietsch and James Orr present the taxa in phylogenetic order, based on classifications that reflect the most current scientific knowledge. Illustrated taxonomic keys facilitate fast and accurate species identification. These in-depth, thoroughly documented, and yet accessible volumes will prove invaluable to marine biologists and ecologists, natural resource managers, anglers, divers, students, and all who want to learn about, marvel over, and preserve the vibrant diversity of Salish Sea marine life. Comprehensive accounts of 260 fish species Brilliant color plates of all treated species Illustrated taxonomic keys for easy species identification In-depth history of Salish Sea research and exploration
Download or read book Marine Anthropogenic Litter written by Melanie Bergmann and published by Springer. This book was released on 2015-06-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.

Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.
