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.

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.

The Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus) is a federally endangered anadromous fish that historically occurred along the Atlantic coast of North American from Canada to Florida. Through the 20th century, overharvest and dam construction resulted in range-wide population declines. Despite two decades of federal protection, many populations have not recovered, and information about the status of many populations is lacking, especially in the Southeastern United States. Recruitment may be a bottleneck for recovery, but habitat use by early juveniles is not well understood. The objectives of this study were to 1) assess the status of Atlantic Sturgeon populations in the St. Johns River in Florida and the St. Marys River in Georgia, at the southern margin of the species' range, and 2) describe seasonal movement by juvenile Atlantic Sturgeon in the Ogeechee, Altamaha, and Satilla Rivers in Georgia. Sturgeon were captured using monofilament gill and trammel nets, and some individuals were tagged with surgically-implanted acoustic transmitters. Fish movements were monitored using an array of passive acoustic receivers distributed throughout the lower river and estuary of each system. We found no evidence of an extant population of Atlantic Sturgeon within the St. Johns River system, but did document the presence of young juveniles in the St. Marys River. Those fish represent a small, but genetically distinct population in a river where the species had previously been thought extirpated. Our results also indicated that both rivers continue to provide seasonally important habitat for migrating adults from other populations. Tagged age-1 river-resident juvenile sturgeon in the Ogeechee, Altamaha, and Satilla Rivers exhibited similar patterns of seasonal habitat use 0́3 during the summer, fish were concentrated in upriver portions of nursery habitat, but during the winter they dispersed downriver and used more polyhaline habitat. Also during the winter of age-2, at least 30% of tagged fish outmigrated from their natal river. These results provide important information for management agencies regarding the status of Atlantic Sturgeon in the two southernmost rivers in their range, as well as helping to fill knowledge gaps about juvenile habitat use and outmigration.
