Sturgeons And Paddlefish Of North America

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.

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.

Selected, reviewed and revised papers from the International Conference on Sturgeon Biodiversity and Conservation held at The American Museum of Natural History in New York on 28-30 July 1994

Paddlefish have become of increasing interest to the aquaculture community in recent years, particularly as a potential new source of seafood and caviar. Native to North America, paddlefish show great promise both domestically and internationally as a commercially viable farmed species. Paddlefish Aquaculture examines all aspects of the biology and culture of these fish, exploring their physiology, production, end products and the economics underlying a successful paddlefish operation. Chapters specifically cover paddlefish biology, propagation and early culture techniques, production for meat and caviar, international culture and history, paddlefish food products, bioaccumulants of contaminants in paddlefish, parasites and diseases, and the economics of paddlefish aquaculture. Paddlefish Aquaculture is a timely practical reference for researchers and producers interested in paddlefish.

Fisherman Mark Spitzer takes readers on an action-packed investigation of the most fierce and fearsome freshwater grotesques of the American West ever to inspire both hatred and fascination. Through the lenses of history, folklore, biology, ecology, and politics, Beautifully Grotesque Fish of the American West depicts the environmental destruction plaguing the most maligned creatures in our midst while subtly interweaving Spitzer's experiences of personal tragedy and self-discovery. Join Spitzer as he noodles for flathead catfish in Oklahoma, snags paddlefish in Missouri, trotline- and electro-fishes American eels in Arkansas, studies razorback suckers in Arizona, bounty hunts for pikeminnows in Washington State, attends a burbot festival in Utah, stirs up Asian carp in Kansas, and breaks the state record for the largest yellow bullhead ever caught in Nebraska. By examining freakish links in a vital chain and working with specialists in the field, Spitzer portrays a planet in environmental crisis and dispels the illusion that our actions don't result in long-term, toxic consequences. Spitzer offers models for fisheries and provides other sources of hope in this informative epic of redemption that ultimately celebrates the wild and resilient beauty and remaining possibilities of the American West.
