This report presents an overview of the findings of regional TRAFFIC studies in Europe, India, East and southern Africa, Southeast Asia, East Asia, Oceania and North and South America. It highlights the fisheries, shark products in trade, and the processing, preparation and use of these products in domestic and international markets. It also discusses the management and conservation implications of this trade.

Sharks are only a small proportion of world recorded fish landings, but they are a versatile and valuable resource. They sustain important fisheries in several countries and are a cheap but valuable source of protein for coastal communities dependent on subsistence fisheries. Sharks are exploited for their meat, fins, teeth, cartilage, liver and other internal organs. This report details species used and methods of preparation for various purposes.

The status of shark species is reviewed based on the available data. A review of the history of shark fisheries demonstrates that intensive shark fisheries are not sustainable. Numerous problems are encountered in assessing shark populations: a general lack of biological and fishery data, lack of suitable models, and lack of validated age estimates. Sharks have an unusual combination of biological characteristics: slow growth and delayed maturation, long reproductive cycles, low fecundity and long life spans. These characteristics make them vulnerable to overfishing. A preliminary evaluation of the status of shark species is made on the basis of historical data, the reproductive potential of each species, and the level of exploitation of the species. In this document, exploited shark species are classified numerically according to their vulnerability. The majority of these species are listed as Category 1, indicating that there are not sufficient data to assess the species. Available data indicate that sharks are very vulnerable and are threatened by overexploitation in many parts of the world.

The key aim of this book is to explore the global conservation and management of sharks. There has been a rapid decline in populations of many shark species, while new science has emerged of the critical role they play in marine ecosystems. However, the authors show that conservation law and policy have been slow to develop, with only a small number of iconic species being protected worldwide. The increase in fishing impact – primarily through shark finning and by-catch - has led to shark conservation receiving greater international attention in recent years. The book explores our current knowledge and status of the law and science in relation to sharks with a particular focus on improving frameworks for their conservation and management. Recent trends are analysed, including shark finning bans that have been put in place in several countries, the widening number of nations establishing shark sanctuaries and the growth of shark-based tourism. The efficacy of current listing processes for endangered species and fisheries regulations is also examined. Tourism is explored as an alternative to fishing and the risks and impacts associated with this industry are analysed. Contributors include leading authorities from universities and conservation organizations in North America, Europe and Australia. A common theme is to emphasise the importance of collaborative governance between various interest groups and the need for inter-disciplinary research and management approaches that are necessary to address the decline in sharks.

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.

The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.

This important and exciting title represents the first authoritative volume focussed on pelagic (open ocean) sharks as a group. Virtually every pelagic shark expert in the world has contributed to this landmark publication which includes the latest data and knowledge on pelagic shark biology, fisheries, management, and conservation. Pelagic sharks face unprecedented levels of exploitation in all the world's oceans through both direct fisheries and by-catch, and effective management for these species is contingent upon solid science and data, which this book brings together for the first time. All those involved in shark biology will need to have a copy of this book.
