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

Book Synopsis Diseases of Coral by : Cheryl M. Woodley
Download or read book Diseases of Coral written by Cheryl M. Woodley and published by John Wiley & Sons. This book was released on 2016-01-26 with total page 613 pages. 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.

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
Book Synopsis A Guide to the Deep-water Sponges of the Aleutian Island Archipelago by : Robert P. Stone
Download or read book A Guide to the Deep-water Sponges of the Aleutian Island Archipelago written by Robert P. Stone and published by . This book was released on 2011 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Furthermore, sponges are extremely fragile and easily damaged by contact with fishing gear. High rates of fishery bycatch clearly indicate a strong interaction between existing fisheries and sponge habitat. Bycatch in fisheries and fisheries-independent surveys can be a major source of information on the location of the sponge fauna, but current monitoring programs are greatly hampered by the inability of deck personnel to identify bycatch. This guide contains detailed pecies descriptions for 112 sponges collected in Alaska, principally in the central Aleutian Islands. It addresses bycatch identification challenges by providing fisheries observers and scientists with the information necessary to adequately identify sponge fauna.Using that identification data, areas of high abundance can be mapped and the locations of indicator species of vulnerable marine ecosystems can be determined.
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 2002-07-09 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.

This book was released on 2011-08 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes major shortcomings in the implementation of U.N. General Assembly resolutions designed to protect the deep-ocean from the destructive impact of fishing. 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.

Download or read book Mediterranean Cold-Water Corals: Past, Present and Future written by Covadonga Orejas and published by Springer. This book was released on 2019-07-10 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: What do we know about Mediterranean Cold (Deep)-Water coral ecosystems? In this book, specialists offer answers and insights with a series of chapters and short papers about the paleoecology, biology, physiology and ecology of the corals and other organisms that comprise these ecosystems. Structured on a temporal axis—Past, Present and Future—the reviews and selected study cases cover the cold and deep coral habitats known to date in the Mediterranean Basin. This book illustrates and explains the deep Mediterranean coral habitats that might have originated similar thriving ecosystems in today’s Atlantic Ocean.
