"Ebert has herein assembled an enormous body of knowledge about California's 43 shark species ranging from shark and human behavior to taxonomic minutiae, along with up-to-date explanations of their ecology, status and fisheries. More importantly, his Herculean effort includes the often-overlooked 25 species of skates, rays and chimaeras. That, along with the fine illustrations of Mat Squillante, should answer any question that a student, diver, natural history buff, or recreational or commercial fisher might ask."—John E. McCosker, coauthor of Great White Shark "The timing of this publication is ideal given the status of some of California's elasmobranch populations and the need for a deeper understanding of their biology, ecology, and fishery management. The book is a comprehensive treatment—if one wants to find out the latest information on any species of shark or ray off California, this is the place to go. An outstanding work!"—Gregor M. Cailliet, Professor, Moss Landing Marine Laboratories, and Director, Pacific Shark Research Center

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.

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.
