DOWNLOAD EBOOKModern 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.

DOWNLOAD EBOOKPaddlefish 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.

DOWNLOAD EBOOKWith 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.

DOWNLOAD EBOOKIn this book the author examines the illegal wildlife trade from multiple perspectives: the historical context, the impact on the environment, the scope of the problem internationally, the sociocultural demand for illegal products, the legal efforts to combat it, and several case studies from inside the trade. The illegal wildlife trade has become a global criminal enterprise, following in the footsteps of drugs and weapons. Beyond the environmental impact, financial profits from the illegal wildlife trade often fund organized crime groups and violent gangs that threaten public safety and security in myriad ways. This innovative volume covers several key questions surrounding the wildlife trade: why is there a demand for illegal wildlife products, which actors are involved in the trade, how is the business organized, and what are the harmful consequences. The author performed ethnographic fieldwork in three key markets: Russia, Morocco, and China, and has constructed a detailed picture of how the wildlife trade operates in these areas. Conversations with informants directly involved in the illegal business ensure unique insights into this lively black market. In the course of his journey the author follows the route of the illegal wildlife trade from poor poaching areas to rich business districts where corrupt officials, legally registered companies, wildlife farms and sophisticated criminal organizations all have a share. A fascinating look inside the world of poachers, smugglers and traders.
