This book was released on 2004 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The greenback cutthroat trout (Oncorhynchus clarki stomias) is classified as a threatened subspecies under the U.S. Endangered Species Act. Non-native brook trout (Salvelinus fontinalis) displace greenback cutthroat trout in montane streams, but the mechanisms for displacement are not understood. In this study, data on population dynamics, body condition, and feeding ecology of greenback cutthroat and brook trout were used in investigating competition for food and predation as potential mechanisms for displacement of greenback cutthroat trout by brook trout. During 2000 and 2001, trout populations and physical habitat were surveyed at 10 stream reaches in the South Platte and Arkansas River drainages in Colorado. Study areas included sites with (1) cutthroat trout only, (2) brook trout only, (3) both species, and (4) both species with experimental removal of brook trout. Complementary techniques, including analysis of stomach contents, stomach fullness, body condition, and stable isotopes of C and N, were used to describe the trophic niche of each species across the 10 sites.

Book Synopsis Strategies for Conserving Native Salmonid Populations at Risk from Nonnative Fish Invasions by : Kurt D. Fausch
Download or read book Strategies for Conserving Native Salmonid Populations at Risk from Nonnative Fish Invasions written by Kurt D. Fausch and published by . This book was released on 2006 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native salmonid populations in the inland West are often restricted to small isolated habitats at risk from invasion by nonnative salmonids. However, further isolating these populations using barriers to prevent invasions can increase their extinction risk. This monograph reviews the state of knowledge about this tradeoff between invasion and isolation. We present a conceptual framework to guide analysis, focusing on four main questions concerning conservation value, vulnerability to invasion, persistence given isolation, and priorities when conserving multiple populations. Two examples illustrate use of the framework, and a final section discusses opportunities for making strategic decisions when faced with the invasion-isolation tradeoff.

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.
Book Synopsis Colorado Greenback Cutthroat Trout by : Jim Rubingh

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.
