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

The report concerns precious (red, pink, white and black) coral species within the hexacoral order Antipatharia, and the octocoral family Coralliidae. According to the requirements of CITES Decision 17.191, the study considers all available data and information on the biology, population status, use and trade in each species, including the identification of gaps in such data and information. It contains information on the management and harvest regulation schemes for these coral species, with the aim of considering the effectiveness of their management and conservation. The report intends to inform the CITES parties of the status of the management and trade of precious corals, in order to provide guidance on the actions needed to enhance the conservation and sustainable use of precious corals.

DOWNLOAD EBOOK →Cold-water coral ecosystems figure the formation of large seabed structures such as reefs and giant carbonate mounds; they represent unexplored paleo-environmental archives of earth history. Like their tropical cousins, cold-water coral ecosystems harbour rich species diversity. For this volume, key institutions in cold-water coral research have contributed 62 state-of-the-art articles on topics from geology and oceanography to biology and conservation, with some impressive underwater images.

The 13 chapters use state-of-the-art reviews and critiques of nearly all of the major topics in this diverse and rapidly growing field. Topics include: patterns of larval diversity, reproductive energetics, spawning ecology, life history theory, larval feeding and nutrition, larval mortality, behavior and locomotion, larval transport, dispersal, population genetics, recruitment dynamics and larval evolution. Written by the leading new scientists in the field, chapters define the current state of larval ecology and outline the important questions for future research.
