Book Description
This guide includes a selection of shark and ray species occurring in the Wider Caribbean Region, that is the waters of the Caribbean Sea, Gulf of Mexico, and the waters of the Atlantic Ocean adjacent thereto. In total, 41 shark and 20 ray species selected as being most relevant to commercial fisheries or vulnerable to exploitation due to their life history characteristics, are included. Of these, 29 shark and 9 ray species are presented in a full species card and depicted with a colour illustra tion and photo. Additionally, short accounts of 12 shark and 11 ray species that are less common in the region and could be misidentified with more common species, are also included. These are depicted with a black and white illustration and key distinguishing features are highlighted allowing for easy and accurate identification in the field. This guide is intended to help fishery workers collecting catch data in the field in the identification of the sharks and rays they might encounter for th e specific purpose of improving the quality of catch and landings data.

Book Description
This volume presents a fully illustrated field guide for the identification of the sharks and rays most relevant to the fisheries of the Mediterranean and Black Sea. An extensive literature review was carried out for the preparation of this document. A total of 49 sharks, 34 batoids and 1 chimaera are fully treated. The presence of 5 sharks and 2 batoids included in this field guide, need, however, to be confirmed. The guide includes sections on technical terms and measurements for sharks and batoids, and fully illustrated keys to those orders and families that occur in the region. Each species account includes: at least one annotated illustration of the species highlighting its relevant identification characters; basic information on nomenclature, synonyms and possible misidentifications; FAO common names; basic information on size, habitat and biology, distribution, importance to fisheries, and conservation and exploitation status.

Book Description
The First meeting of the WECAFC/OSPESCA/CRFM/CITES/CFMC Working Group on shark conservation and management was held in Barbados on 17-19 October 2017. The meeting was attended by 30 shark fisheries experts from 15 WECAFC member countries and partner agencies. The meeting recognized the decline in various shark and ray stocks in the Caribbean region, as well as the need to conserve the threatened species among them. The meeting stressed the importance of harmonizing conservation and management measures with various international and regional conventions for the protection of these often-migratory species, as well as with measures by regional fisheries management bodies in the Atlantic. The fisheries experts recommended amongst others that the countries in the region should prohibit the removal of shark fins at sea and require that all sharks be landed with their fins naturally attached through the point of first landing of the sharks. The experts recommended the prohibition of targeted fisheries for iconic species, such as whale sharks, sawfishes and manta rays. The experts worked on a regional shark stocks and fisheries status assessment and a Regional Plan of Action for the conservation and management of sharks and rays in the WECAFC area.

Book Description
Manta and devil rays are some of the most intriguing creatures in the ocean. Driven forward by powerful beats of wing-like pectoral fins, these filter feeders search the waters for prey, their horn-like head fins giving rise to ancient mariners’ tales of fearsome devilfish dragging boats into the ocean depths. Beloved by scuba divers and marine biologists alike, these impressive animals have never had a comprehensive field guide dedicated to them—until now. Guide to the Manta and Devil Rays of the World includes detailed information on the identification, characteristics, threats, and distribution for each species in this family. Illustrated with more than 200 color photos, drawings, and plates, this guide also contains an expansive introduction to the general taxonomy, biology, and behavior of these iconic animals. This book will be an essential resource for fisheries management and international trade enforcement, and for anyone involved in ongoing manta and devil ray research and conservation. The first dedicated field guide for manta and devil rays Exhaustive treatment of every aspect related to their identification and biology Filled with 200+ color drawings, photos, and diagrams
