DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKSharks 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.
