Title on accompanying CD-ROM: Sharks, batoids and chimaeras of the North Atlantic

This volume is a comprehensive, fully illustrated catalogue of the sharks, batoid fishes, and chimaeras of the North Atlantic, encompassing FAO Fishing Areas 21 and 27. The present volume includes 11 orders, 32 families, 66 genera, and 148 species of cartilaginous fishes occurring in the North Atlantic. The Catalogue includes a section on standard measurements for a shark, batoid, and chimaera, with associated terms. It provides accounts for all orders, families, and genera and all keys to taxa are fully illustrated. Information under each species account includes: valid modern names and original citation of the species; synonyms; the English, French, and Spanish FAO names for the species; a lateral view for sharks and chimaeras, dorsal and often also ventral view for batoids, and often other useful illustrations; field marks; diagnostic features; distribution, including a GIS map; habitat; biology; size; interest to fisheries and human impact; local names when available; a remarks sections; and literature. The volume is fully indexed and also includes sections on terminology and measurements including an extensive glossary, a list of species by FAO Statistical Areas, and a dedicated bibliography.

The 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

This guide contains the illustrated key to orders, families, genera and species to the Chondrichthyes of the Mediterranean and Black Seas (FAO fishing area 37), currently represented by 38 sharks, 48 batoids and 2 chimaeras. The species are described following the taxonomic order and are grouped in functional groups. Near the illustration of each species, the relevant diagnostic features are complemented by a set of icons representing the management measures and the data collection requirements as per existing GFCM recommendations. The technical terms and the minimum standard measurements are provided as annexes.

Elasmobranch - describes a group of fish without a hard bony skeleton, including sharks, skates, and rays.

Sharks 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.

This 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.
