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: Over the last century, native trout have experienced dramatic population declines, particularly in larger river systems where habitats associated with different spawning life history forms have been lost through habitat degradation and fragmentation. The resulting decrease in life history diversity has affected the capacity of populations to respond to environmental variability and disturbance. Unfortunately, because few large rivers are intact enough to permit full expression of life history diversity, it is unclear what patterns of diversity should be a conservation target. In this study, radiotelemetry was used to identify spawning and migration patterns of Snake River Finespotted Cutthroat Trout Oncorhynchus clarkii behnkei in the upper Snake River. Individuals were implanted with radio tags in October 2007 and 2008, and monitored through October 2009. Radio-tagged cutthroat trout in the upper Snake River exhibited variation in spawning habitat type and location, migration distance, spawn timing, postspawning behavior, and susceptibility to mortality sources. Between May and July, Cutthroat Trout spawned in runoff-dominated tributaries, groundwater-dominated spring creeks, and side channels of the Snake River. Individuals migrated up to 101 km from tagging locations in the upper Snake River to access spawning habitats, indicating that the upper Snake River provided seasonal habitat for spawners originating throughout the watershed. Postspawning behavior also varied; by August each year, 28% of spring-creek spawners remained in their spawning location, compared with 0% of side-channel spawners and 7% of tributary spawners. These spawning and migration patterns reflect the connectivity, habitat diversity, and dynamic template of the Snake River. Ultimately, promoting life history diversity through restoration of complex habitats may provide the most opportunities for cutthroat trout persistence in an environment likely to experience increased variability from climate change and disturbance from invasive species.

This book was released on 2007 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Snake River fine-spotted cutthroat trout (SRC) diverged 10,000-20,000 years ago from the Yellowstone cutthroat trout (YSC). The two exhibit distinct morphological differences based mainly in their unique spotting patterns. Most previous research of the SRC has been related to its value as a fishery species. This research fills a hole in the literature by investigating ecological preferences of the SRC, specifically with respect to habitat, and as compared to the USC. Results suggest that the SRC prefers streams with high discharge. The SRC was found only in the main stem of the Snake River and did not enter tributaries within the study area. Thisis likely due to a combination of the following: (1) the SRC exhibits a genetic preference for faster, larger streams; (2) the SRC has not entered the tributaries because of steeper gradients; )3) the tributaries are too far from the main range of the SRC (Palisades Reservoir to Jackson Lake); (4) the tributaries within the study area are much higher in elevation than the streams within the main range of the SRC. This analysis of the ecological differences between the YSC and the SRC is important to confidently identify the SRC as a distinct subspecies, as it is currently considered undescribed. Moreover, an understanding of habitat preferences will aid conservation and management efforts of key habitat types and hopefully lead to further protection of the cutthroat trout.
