People of the Sturgeon tells the poignant story of an ancient fish. Wanton harvest and habitat loss took a heavy toll on these prehistoric creatures until they teetered on the brink of extinction. But, in Wisconsin, lake sturgeon have flourished because of the dedicated work of Department of Natural Resources staff, university researchers and a determined group of spearers known as Sturgeon For Tomorrow. Thanks to these efforts, spearers can still flock by the thousands to frozen Lake Winnebago each winter to take part in a ritual rooted in the traditions of the Menominee and other Wisconsin Indians. A century of sturgeon management on Lake Winnebago has produced the world's largest and healthiest lake sturgeon population. Through a fascinating collection of images, stories and interviews, People of the Sturgeon chronicles the history of this remarkable fish and the cultural traditions it has spawned. The authors introduce a colorful cast of characters with a good fish tale to tell. Color photos by the late Bob Rashid and images from the Wisconsin Historical Society evoke both the magical and the mortal. Weaving together myriad voices and examining the sturgeon's profound cultural impact, the authors reveal how a diverse group of people are now joined together as "people of the sturgeon."

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.

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).

The first book of its kind to explore this magnificent creature, this collected volume captures many aspects of the remarkable Great Lakes sturgeon, from the mythical to the critically real. Lake sturgeon are sacred to some, impressive to many, and endangered in the Great Lakes. A fish whose ancestry reaches back millions of years and that can live over a century and grow to six feet or more, the Great Lakes lake sturgeon was once considered useless, then overfished nearly to extinction. Though the fish is slowly making a comeback thanks to the awareness-raising efforts of Native Americans, biologists, and sturgeon supporters, it remains to be seen if conservation and stewardship will continue to the degree this remarkable animal deserves. Blending history, biology, folklore, environmental science, and policy, this accessible book seeks to reach a broad audience and tell the story of the Great Lakes lake sturgeon in a manner as diverse as its subject.

In this thoughtful and highly readable book, Noël Sturgeon illustrates the myriad and insidious ways in which American popular culture depicts social inequities as “natural” and how our images of “nature” interfere with creating solutions to environmental problems that are just and fair for all. Why is it, she wonders, that environmentalist messages in popular culture so often “naturalize” themes of heroic male violence, suburban nuclear family structures, and U.S. dominance in the world? And what do these patterns of thought mean for how we envision environmental solutions, like “green” businesses, recycling programs, and the protection of threatened species? Although there are other books that examine questions of culture and environment, this is the first book to employ a global feminist environmental justice analysis to focus on how racial inequality, gendered patterns of work, and heteronormative ideas about the family relate to environmental questions. Beginning in the late 1980s and moving to the present day, Sturgeon unpacks a variety of cultural tropes, including ideas about Mother Nature, the purity of the natural, and the allegedly close relationships of indigenous people with the natural world. She investigates the persistence of the “myth of the frontier” and its extension to the frontier of space exploration. She ponders the popularity (and occasional controversy) of penguins (and penguin family values) and questions assumptions about human warfare as “natural.” The book is intended to provoke debates—among college students and graduate students, among their professors, among environmental activists, and among all citizens who are concerned with issues of environmental quality and social equality.

The Siberian sturgeon, Acipenser baerii Brandt 1869 is the most widely farmed sturgeon species. Continuing from Volume 1, which focuses on the biology of the species, the present Volume 2 in turn examines farming aspects. It is divided into six parts, the first of which deals with reproduction and early ontogenesis, i.e. reproductive cycles, controlled reproduction, sperm cryoconservation, and weaning of larvae. The second covers the growing phase with a focus on food and feeding (management, fish meal replacement, potential endocrine disruptions, usefulness of prebiotics and immunostimulants, and nitrogen excretion). Production-related data are the focus of the third part and include: characteristics (countries, structures of production, evolution in production, economic features) of the gross production of the species (meat and caviar) worldwide, a method for assessing the quality of caviars, off-flavors management, and an example of production of fingerlings for restocking. Part four addresses selected long-term management issues: genetic variability of brood stocks, genome manipulation and sex control, and the advantages of hybrids. The next three chapters constitute the fifth part, which is devoted to health status (immunology and welfare). In closing, the absence of ecological risks of introducing the species in non-native waters is shown using two long-term documented examples (Russia and France). Three methodological chapters round out the volume, covering: in vitro incubation of ovarian follicles, a richly illustrated library of echographies and photos, and a detailed presentation of oxygen demand studies.

The biology of the Siberian sturgeon, Acipenser baerii Brandt 1869, has become a very attractive subject of investigation for biologists since the 1980s. This volume 1 is part of a two-volume set devoted to the species, the second of which focuses on farming. The present volume is divided into three parts: Biology and ecology, Biology and physiology of reproduction, and Ecophysiology, i.e. adaptation to the environment. The first part addresses a broad range of topics, such as: the ecology, including a new approach to species-specificity, a new insight on the mineralization of vertebral elements, two approaches to sex determination, transposable elements in the gonads, early ontogeny, olfaction and gustation, nutrition and swimming. The second part includes neurochemical and anatomical descriptions of the central nervous system and an updated version of the oogenesis, the characteristics of both sperm and spermatozoa, and a synthesis on gonadal steroids (synthesis, plasmatic levels and biological activities). In turn, the third part reveals how the physiology of the species changes depending on environmental factors such as oxygen, ammonia, and nitrite. Some fundamental consequences of ammonia are developed (sublethal and lethal levels, effects on gill epithelium and haematology, acid-base balance, on AA and adenyl nucleotides levels in plasma, brain and muscle tissue). In addition, the book includes two methodological chapters dealing with fish dorsal aortic cannulation and respiration physiology.
