Book Description
Feed your fascination with sharks! This complete resource enlightens readers on the biology, ecology, and behavior of sharks with approachable explanations and more than 250 stunning color illustrations. Studies of shark biology have flourished over the last several decades. An explosion of new research methods is leading to a fascinating era of oceanic discovery. Shark Biology and Conservation is an up-to-date, comprehensive overview of the diversity, evolution, ecology, behavior, physiology, anatomy, and conservation of sharks. Written in a style that is detailed but not intimidating by world-renowned shark specialists Dan Abel and Dean Grubbs, it relays numerous stories and insights from their exciting experiences in the field. While explaining scientific concepts in terms that non-specialists and students can understand, Abel and Grubbs reveal secrets that will illuminate even the experts. The text provides readers with a robust and wide range of essential knowledge as it • introduces emerging as well as traditional techniques for classifying sharks, understanding their behavior, and unraveling the mysteries of their evolution; • draws on both established shark science and the latest breakthroughs in the field, from molecular approaches to tracking technologies; • highlights the often-neglected yet fascinating subject of shark physiology, including heart function, sensory biology, digestion, metabolic performance, and reproduction; • addresses big picture ecological questions like "Which habitats do sharks prefer?" and "Where do sharks migrate and for what purpose?"; • describes the astonishing diversity of sharks' adaptations to their environment; • discusses which shark conservation techniques do and don't work; and • comments on the use and misuse of science in the study of sharks. Enhanced by hundreds of original color photographs and beautifully detailed line drawings, Shark Biology and Conservation will appeal to anyone who is spellbound by this wondrous, ecologically important, and threatened group, including marine biologists, wildlife educators, students, and shark enthusiasts.
General Fisheries Commission for the Mediterranean – Report of the forty-fifth session

Category : Technology & Engineering
Languages : en
Pages : 253
Book Description
This report summarizes the discussions held during the forty-fifth session of the General Fisheries Commission for the Mediterranean and twelfth session of the Committee on Administration and Finance. During the session, progress in activities related to fisheries, aquaculture, compliance and other strategic activities was reviewed. The Commission adopted 17 binding recommendations and four resolutions related to fisheries management and conservation, aquaculture and compliance. Moreover, the Commission adopted the revised GFCM Rules of Procedure and approved the proposal for the appointment of the new GFCM Executive Secretary. Finally, the Commission adopted its programme of work for the next intersession and approved its autonomous budget for 2023, 2024 and 2025, as well as a number of strategic actions to be funded through extrabudgetary resources. The Commission also endorsed the new Bureau of the Committee on Administration and Finance and extended the mandate of the Bureau of the Scientific Advisory Committee on Aquaculture until 2024.
Sharks and Their Relatives
Author: Merry CamhiPublisher: IUCN
ISBN: 9782831704609
Category : Nature
Languages : en
Pages : 50
Book Description
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.

Pages : 144
Book Description
The Panel met in response to the agreement by the 25th and 26th sessions of the FAO Committee on Fisheries (COFI) to discuss proposals regarding the Convention on International Trade in endangered Species of Wild Fauna and Flora (CITES), The objectives of the Panel were to assess each proposal from a scientific perspective in accordance with the CITES biological listing criteria; and to consider technical aspects of the proposal in relation to biology, ecology, trade and management issues, as well as the likely effectiveness for conservation. Seven proposals were evaluated by the Panel.
Physiology of Elasmobranch Fishes
Author: Trevor J. ShuttleworthPublisher: Springer Science & Business Media
ISBN: 3642733360
Category : Medical
Languages : en
Pages : 329
Book Description
There can be little doubt that, to use the parlance of the advertising world, the elasmobranch fishes have a "high profile image" in today's world. To most mem bers of the general public they are seen as terrors of the deep, perfect aquatic predators, and the stars (or more acurately, the villains) of major Hollywood movie films and innumerable television nature programmes. Such an image belies the fact that the vast majority of elasmobranch species feed on invertebrates and that, for man, the threat from shark attack is infinitesimal compared with even being struck by lightning! Similarly, there can be few biologists who have not carried out the classic vertebrate dissection of the dogfish at some stage early in the formative years of their scientific education. Yet elasmobranch species make up only a small proportion, perhaps little more than I %, of all vertebrates, and there are probably nearly 50 times as many teleost species as there are elasmobranchs. It is also curious that, as subjects for modern research, elasmobranchs seem to be chosen sometimes for their unique physiological characteristics and at other times because they represent excellent model systems for the study of some general process. Equally, it is for both these, seemingly contradictory, reasons that this book was proposed.
