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 the tradition of Cod and Olives: a fascinating journey into the hidden history, culture, and commerce of caviar. Once merely a substitute for meat during religious fasts, today caviar is an icon of luxury and wealth. In Caviar, Inga Saffron tells, for the first time, the story of how the virgin eggs of the prehistoric-looking, bottom-feeding sturgeon were transformed from a humble peasant food into a czar’s delicacy–and ultimately a coveted status symbol for a rising middle class. She explores how the glistening black eggs became the epitome of culinary extravagance, while taking us on a revealing excursion into the murky world of caviar on the banks of the Volga River and Caspian Sea in Russia, the Elbe in Europe, and the Hudson and Delaware Rivers in the United States. At the same time, Saffron describes the complex industry caviar has spawned, illustrating the unfortunate consequences of mass marketing such a rare commodity. The story of caviar has long been one of conflict, crisis, extravagant claims, and colorful characters, such as the Greek sea captain who first discovered the secret method of transporting the perishable delicacy to Europe, the canny German businessmen who encountered a wealth of untapped sturgeon in American waters, the Russian Communists who created a sophisticated cartel to market caviar to an affluent Western clientele, the dirt-poor poachers who eked out a living from sturgeon in the aftermath of the Soviet collapse and the “caviar Mafia” that has risen in their wake, and the committed scientists who sacrificed their careers to keep caviar on our tables. Filled with lore and intrigue, Caviar is a captivating work of culinary, natural, and cultural history.

Book Description
The landscape of southwestern Wyoming around the ghost town of Fossil is beautiful but harsh; a dry, high mountain desert with cool nights and long, cold winters inhabited by a sparse mountain desert community. But during the early Eocene, more than fifty million years ago, it was a subtropical lake, surrounded by volcanoes and forests and teeming with life. Buried within the sun-baked limestone is spectacular evidence of the lush vegetation and plentiful fauna of the ancient past, a transitional ecosystem giving us clues to how North America recovered from a great extinction event that wiped out dinosaurs and the majority of all species on the planet. Paleontologists have been conducting excavations at Fossil Butte for more than 150 years, and with The Lost World of Fossil Lake, one of the world’s leading experts on the fossils from this spectacular locality takes readers on a fascinating journey through the history of the discovery and exploration of the site. Deftly mixing incredible color photographs of the remarkable fossils uncovered at the site with an explanation of their evolutionary significance, Grande presents an unprecedented, comprehensive portrait of the site, its treasures, and what we’ve learned from them. Grande presents a broad range of fossilized organisms from Fossil Lake—from single-celled algae to palm trees to crocodiles—and together they make this long-extinct community come to life in all its diversity and splendor. A field guide and atlas round out the book, enabling readers to identify and classify the majority of the known fossils from the site. Lavishly produced in full color, The Lost World of Fossil Lake is a stunning reminder of the intellectual and physical beauty of scientific investigation—and a breathtaking window onto our planet’s long-lost past.

Book Description
With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Book Description
Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.
