This book was released on 2014 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first in situ exploration of deep-sea coral habitat in the central Aleutian Islands in 2002 confirmed expectations that had been based on fishery bycatch and research survey records which indicate corals are widespread, diverse, and abundant. This paper reports observations from analysis of video collected during 2003 and 2004 in a study area that expanded the range of earlier observations to depths beyond current fishing activities (1000 m) and encompassed the entire central Aleutian Island region. Video of the seafloor was collected at 17 sites with a manned submersible to depths of 365 m and a remotely operated vehicle to 2947 m. Corals, sponges, and other emergent epifauna were widely distributed throughout the study area and present at all depths. Changes in density and species richness were observed at depths of 400-700 m, with abundance and diversity increasing as depth decreased. The distribution of individual fishes, crabs, and octopods was examined relative to emergent epifauna: 63% of the fishes, crabs, and octopods were found in the same sampled video frames as were corals, 69% of them were found in the same frames with sponges, and 55% of them were found in the same frames with "other" emergent epifauna. Most species at depths

Available in PDF, EPUB and Kindle. Book excerpt: Coral disease is quickly becoming a crisis to the health and management of the world’s coral reefs. There is a great interest from many in preserving coral reefs. Unfortunately, the field of epizootiology is disorganized and lacks a standard vocabulary, methods, and diagnostic techniques, and tropical marine scientists are poorly trained in wildlife pathology, veterinary medicine, and epidemiology. Diseases of Coral will help to rectify this situation.

This book was released on 2016 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Using an autonomous underwater vehicle (AUV) and towed camera system (TCS), deep-sea corals, sponges, and seafloor habitats were visually surveyed for the first time in areas of longtime trawl fishing off northern California. During an 11-day cruise aboard the R/V Point Sur 8-18 September 2014, researchers completed 6 dives with the AUV and 9 deployments of the TCS, and spent over 42 hours underwater at depths of 586-1169 meters from the Oregon- California border to the Mendocino Ridge (...) This report provides a summary of the methods and results from these underwater surveys of DSC&S off northern California. This was a collaborative effort among investigators from NOAA National Marine Fisheries Service (Southwest Fisheries Science Center, Northwest Fisheries Science Center [NWFSC], Pacific Islands Fisheries Science Center [PIFSC], and Alaska Fisheries Science Center [AFSC]) and several universities including California State University (Humboldt State University and Moss Landing Marine Laboratories), University of California Santa Cruz, and Oregon State University"--Page 1.

Download or read book Seamounts written by Tony J. Pitcher and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seamounts are ubiquitous undersea mountains rising from the ocean seafloor that do not reach the surface. There are likely many hundreds of thousands of seamounts, they are usually formed from volcanoes in the deep sea and are defined by oceanographers as independent features that rise to at least 0.5 km above the seafloor, although smaller features may have the same origin. This book follows a logical progression from geological and physical processes, ecology, biology and biogeography, to exploitation, management and conservation concerns. In 21 Chapters written by 57 of the world’s leading seamount experts, the book reviews all aspects of their geology, ecology, biology, exploitation, conservation and management. In Section I of this book, several detection and estimation techniques for tallying seamounts are reviewed, along with a history of seamount research. This book represents a unique and fresh synthesis of knowledge of seamounts and their biota and is an essential reference work on the topic. It is an essential purchase for all fisheries scientists and managers, fish biologists, marine biologists and ecologists, environmental scientists, conservation biologists and oceanographers. It will also be of interest to members of fish and wildlife agencies and government departments covering conservation and management. Supplementary material is available at: www.seamountsbook.info
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 2002-07-09 with total page 136 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.
Download or read book Cold Water Corals written by J. Murray Roberts and published by Cambridge University Press. This book was released on 2009-04-30 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are more coral species in deep, cold-waters than in tropical coral reefs. This broad-ranging treatment is the first to synthesise current understanding of all types of cold-water coral, covering their ecology, biology, palaeontology and geology. Beginning with a history of research in the field, the authors describe the approaches needed to study corals in the deep sea. They consider coral habitats created by stony scleractinian as well as octocoral species. The importance of corals as long-lived geological structures and palaeoclimate archives is discussed, in addition to ways in which they can be conserved. Topic boxes explain unfamiliar concepts, and case studies summarise significant studies, coral habitats or particular conservation measures. Written for professionals and students of marine science, this text is enhanced by an extensive glossary, online resources, and a unique collection of colour photographs and illustrations of corals and the habitats they form.

This is the first comprehensive scientific review of the mgmt. of deep-sea fishing on the high seas globally, this report examines the data available from Regional Fisheries Management Organization (RFMOs), the bodies tasked with implementing the U.N. resolutions. It concludes that ¿RFMOs are failing to manage deep-sea bottom fisheries on the high seas sustainably with respect to target and by-catch species. For most fisheries there is little or no info. on the status of stocks and in many cases we do not even know what is being caught where." Illus. A print on demand report.
