Book Description
Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.

Book Description
Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).

Book Description
The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen’s organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.

Book Description
Because of their threatened status, sturgeons have been the focus of broad scientific interest. This book provides new information on freshwater, estuarine, and marine habitats of anadromous sturgeons; examines threats to habitats and populations; and reviews management and population trends in light of progress on recovery of U.S. Atlantic sturgeon populations since fishing was banned.

Book Description
This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

Book Description
"In Philosopher Fish Carey immerses himself in the world of sturgeon, the fish that lays these golden eggs. Ancient, shrouded in mystery, inexplicable in several of its behaviors, the sturgeon has a fascinating biologic past-and a very uncertain future. This new edition brings the story up to date"--
