Field Identification Guide to the Sharks and Rays of the Mediterranean and Black Sea


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.




Field Identification Guide to the Sharks and Rays of the Red Sea and Gulf of Aden


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 Red Sea and Gulf of Aden. An extensive literature review and two field surveys in the region were carried out for the preparation of this document. A total of 49 sharks and 45 batoids reliably reported for the region are listed and those common in the fisheries or likely to be found through fisheries operations are fully treated. 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. Color plates for a large number of the species are included.




Sharks, rays and chimaeras in Mediterranean and Black Seas


Book Description

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.




Elasmobranchs of the Mediterranean and Black Sea


Book Description

In many fisheries they are, however, often landed and marketed.




Report of the Technical Workshop on the Status, Limitations and Opportunities for Improving the Monitoring of Shark and Fisheries Trade


Book Description

The technical workshop considered global and country specific information on shark fisheries and trade to identify limitations and strategies for improving their monitoring. Reports from a selected number of main shark fishing and trading nations described the status of shark fisheries and the efforts towards the development of a National Plan of Action for Sharks. The workshop recommended actions to promote the implementation of National Plans of Action for Sharks and to address specific problems affecting catch and trade monitoring, including lack specificity in data, underestimated catch volumes, and limitations in the customs codes used in trade monitoring.--Publisher's description.




Spark from the Deep


Book Description

How encounters with strongly electric fish informed our grasp of electricity. Spark from the Deep tells the story of how human beings came to understand and use electricity by studying the evolved mechanisms of strongly electric fish. These animals can shock potential prey or would-be predators with high-powered electrical discharges. William J. Turkel asks completely fresh questions about the evolutionary, environmental, and historical aspects of people’s interest in electric fish. Stimulated by painful encounters with electric catfish, torpedos, and electric eels, people learned to harness the power of electric shock for medical therapies and eventually developed technologies to store, transmit, and control electricity. Now we look to these fish as an inspiration for engineering new sensors, computer interfaces, autonomous undersea robots, and energy-efficient batteries. Praise for Spark from the Deep “This beautifully written and exhaustively researched book traces the links between experiments on strongly electric fish and scientific understanding of electricity . . . Turkel’s book is a joy to read; it will entertain and educate scientists, historians, and anyone with an interest in the natural world.” —Choice “Turkel’s book convincingly reminds us that all the laptops and gadgets we surround ourselves with are remixes; altered versions of strongly electric fish. For that strange and insightful observation, this book ought to be widely read and enjoyed.” —Chris Conway, Endeavour “[I]t is refreshing to explore a book which takes seriously ancient encounters with manifestations of natural electricity as precursors to more recent innovations.” —James F. Stark, The British Journal for the History of Science
