Available in PDF, EPUB and Kindle. Book excerpt: Once thought to be extinct, Colorado's famed greenback cutthroat trout is in the process of making a remarkable comeback. There are now over 50 waters along the Colorado Front Range where fishermen can experience the thrill of catching this beautiful fish. Colorado Greenback Cutthroat Trout: A Fisherman's Guide will tell you about the biology, history, and the amazing recovery of the greenback, along with information on where and how to catch this unique and colorful fish. The survival of the greenback cutthroat now hinges on the combined efforts of state and federal agencies, wildlife organizations, and the volunteer work of numerous fishermen and citizens. This book is dedicated to those individuals and organizations, and to the premise that wild native trout such as the greenback are more than worth all of our conservation efforts.

Download or read book Recovery History of Greenback Cutthroat Trout written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The greenback cutthroat trout (Oncorhynchus clarki stomias) is native to the mountain and foothill waters of the South Platte and Arkansas river basins in Colorado. This taxon declined rapidly beginning near the turn of the century and was listed under the Endangered Species Act in 1973. We assembled all available information from a variety of sources to document recovery efforts from 1957 to 1999. For each greenback cutthroat trout population, we noted (1) the characteristics of recovery waters and dates of population discovery or introduction; (2) fish abundance estimates; (3) analyses of genetic purity; (4) salmonid fauna, removal efforts, and reinvasions; and (5) dates, sources, and numbers of fish used to establish populations. For each hatchery used to assist recovery, we noted (1) sources and numbers of fish delivered to them; (2) sources, sex ratios, and production of fish used to create particular year classes; and (3) dates, numbers, and sizes of hatchery fish shipped to establish wild populations or supplement other hatchery stocks.

Download or read book Genetic Status of Isolated Populations of Colorado River Cutthroat Trout (Oncorhynchus Clarkii Pleuriticus) in the North Fork Little Snake River Drainage, Wyoming written by Rachel Van Horne and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In many cases of accidental isolation, the populations above the barriers have limited habitat and small population sizes that make them vulnerable to extinction and may hold evolutionary value to the species as a whole. All the isolated populations in the drainage currently have high genetic differentiation among tributaries, low genetic diversity within each tributary, a suggestion of isolation by distance, and effective population sizes that are below the recommendation for long- term persistence. This structure represents natural and anthropogenic influences, but the presence of the human-constructed barriers in the headwater tributaries puts the larger core conservation group at risk into the future. Although the genetic diversities within the populations are low, the high genetic differentiations among populations suggest that each population may have its own unique contribution to the evolutionary value to the drainage as a whole and each is important to conserve into the future.

Download or read book Genetic Considerations for the Conservation and Management of Yellowstone Cutthroat Trout (Oncorhynchus Clarkii Bouvieri) in Yellowstone National Park written by David Joel Janetski and published by . This book was released on 2006 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: A key component to conservation is an accurate understanding of genetic subdivision within a species. Despite their ecological and economic importance, relatively little is understood about the genetic structuring of Yellowstone cutthroat trout in Yellowstone National Park. Here, we use traditional (Fst, Rst, Nm, and AMOVA) and modern (Bayesian assignment tests, coalescent theory, and nested clade analysis) analytical approaches to describe the population genetic subdivision of cutthroat trout spawning populations in Yellowstone Lake and to identify genetically distinct population segments throughout Yellowstone National Park. Evidence for restricted gene flow between spawning populations within Yellowstone Lake was detected using nested clade analysis. This is the first molecular evidence for restricted gene flow between spawning populations in Yellowstone Lake. In contrast, traditional methods such as Fst and Rst as well as the Bayesian clustering program STRUCTURE v2.0 failed to detect evidence for restricted gene flow. Across our sampling range within Yellowstone National Park, eleven genetically distinct cutthroat trout population segments were detected. These showed a general pattern of small, isolated populations with low genetic diversity in headwater streams and wide-spread, genetically diverse populations in higher-order rivers. We recommend populations be managed to maintain current levels of genetic diversity and gene flow. Based on the recent decline of and distinct morphological, behavioral, and genetic nature of cutthroat trout in Yellowstone Lake, we recommend the Yellowstone Lake spawning populations collectively be recognized as an evolutionarily significant unit.

Download or read book Cutthroat written by Pat Trotter and published by Univ of California Press. This book was released on 2008 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cutthroat tells the full story of the genuine native trout of the American West. This new edition, thoroughly revised and updated after 20 years, synthesizes what is currently known about one of our most interesting and colorful fishes, includes much new information on its biology and ecology, asks how it has fared in the last century, and looks toward its future. In a passionate and accessibly written narrative, Patrick Trotter, fly fisher, environmental advocate, and science consultant, details the evolution, natural history, and conservation of each of the cutthroat's races and incorporates more personal reflections on the ecology and environmental history of the West's river ecosystems. The bibliography now includes what may be the most comprehensive and complete set of references available anywhere on the cutthroat trout. Written for anglers, nature lovers, environmentalists, and students, and featuring vibrant original illustrations by Joseph Tomelleri, this is an essential reference for anyone who wants to learn more about this remarkable, beautiful, and fragile western native.

Available in PDF, EPUB and Kindle. Book excerpt: North American deserts—lands of little water—have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.
