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.
Climate Ghosts
"Langston focuses on three ghost species in the Great Lakes watershed-woodland caribou, common loons, and lake sturgeon. Their traces are still present in DNA, small fragmented populations, or in lone individuals. We can still restore them, if we make the hard choices necessary for them to survive"--
Scientific Foundations of Zoos and Aquariums
Using first-person stories and approachable scientific reviews, this volume explores how zoos conduct and support science around the world.
Environmental History of the Hudson River
Winner of the 2012 Award for Excellence presented by the Greater Hudson Heritage Network The diverse contributions to Environmental History of the Hudson River examine how the natural and physical attributes of the river have influenced human settlement and uses, and how human occupation has, in turn, affected the ecology and environmental health of the river. The Hudson River Valley may be America's premier river environmental laboratory, and by bringing historians and social scientists together with biologists and other physical scientists, this book hopes to foster new ways of looking at and talking about this historically, commercially, and aesthetically important ecosystem. Native peopl...
Paddlefish Aquaculture
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.
Biology, Conservation and Sustainable Development of Sturgeons
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...
Freshwater Fishes of North America
"The second volume of the definitive reference Freshwater Fishes of North America, encompassing families Characidae to Poeciliiadae, is the result of decades of analysis by leading fish experts from universities and reserch laboratories across North America" -- Page 4 de la couverture du volume 2.
Fishes of Arkansas
The second edition of Fishes of Arkansas, in development for more than a decade, is an extensive revision and expansion of the first edition, including reclassifications, taxonomic changes, and descriptions of more than thirty new species. An invaluable reference for anyone interested in the state’s fish population—from professional ichthyologists, fisheries biologists, and managers of aquatic resources, to amateur naturalists and anglers—this new edition provides updated taxonomic keys as well as detailed descriptions, photographs, and line drawings to aid identification of the state’s 243 fish species. There is also much information on the distribution and biology of each species, including descriptions of habitat, foods eaten, reproductive biology, and conservation status. This project and the preparation of this publication was funded in part by a grant from the Arkansas Game and Fish Commission.
Paradise Found
The first Europeans to set foot on North America stood in awe of the natural abundance before them. The skies were filled with birds, seas and rivers teemed with fish, and the forests and grasslands were a hunter’s dream, with populations of game too abundant and diverse to even fathom. It’s no wonder these first settlers thought they had discovered a paradise of sorts. Fortunately for us, they left a legacy of copious records documenting what they saw, and these observations make it possible to craft a far more detailed evocation of North America before its settlement than any other place on the planet. Here Steve Nicholls brings this spectacular environment back to vivid life, demonstr...
