DOWNLOAD EBOOKThe definitive field guide to all the sharks, rays and chimaeras of eastern North America The waters off the East Coast of North America are home to an amazing variety of sharks, rays and chimaeras. This groundbreaking, comprehensive and easy-to-use field guide covers all 173 species found along the eastern seaboard of the United States and Canada, including Bermuda and the Bahamas, and extending into the Gulf of Mexico to the Yucatan Peninsula. These are all the species that are encountered in the shallow waters of estuaries and coasts and in the open ocean, including rarely seen deepsea species. Lavishly illustrated throughout, this must-have guide includes detailed species accounts describing key identification features, habitat, biology and status. It also features illustrated key guides that enable users to accurately identify species, comparison plates of similar species, dentition plates and illustrations of egg cases, where known. This an essential guide for fisheries management, trade regulation and shark conservation. The first field guide to cover all 173 species Features hundreds of color illustrations and photos Describes key features, habitat, biology and status Includes depth guides, at-a-glance icons and distribution maps Offers illustrated key guides, species comparisons and dentition plates

DOWNLOAD EBOOKSharks and their relatives, the rays and chimaeras, are the diverse group of cartilaginous fishes that have evolved over 400 million years. Historically considered of low economic value to large-scale fisheries, today many of these fishes have become the target of directed commercial and recreational fisheries around the world, and they are increasingly taken in the by-catch of fisheries targeting other species. This report emphasizes the widely-acknowledged need to improve shark fishery monitoring, expand biological research and take management action. It serves as an introduction to the ecology, status and conservation of the sharks and their relatives for a general audience. Shark fisheries can only be managed sustainably, and shark populations remain viable, with the introduction of new conservation and management initiatives.

DOWNLOAD EBOOKThis book compiles the main findings of the multidisciplinary long-term research program developed in the continental margin of one of the more productive and unknown areas of the world oceans, Northwest Africa. The more than 25,000 preserved fishes and benthic invertebrates and quantitative data collected in 342 trawling stations, the 267 oceanographic profiles, the 211 sediment samples and the 28,122 km2 prospected by multi˗beam echo sounding allowed to obtain an overview of the amazing biodiversity of the demersal and benthic fauna inhabiting soft- and hard-bottom habitats, as well as the fascinating geomorphology and oceanography, hidden in the Mauritanian slope.
