Available in PDF, EPUB and Kindle. Book excerpt: Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri were historically distributed in the Yellowstone River drainage (Montana and Wyoming) and the Snake River drainage (Wyoming, Idaho, Utah, Nevada, and probably Washington). Individual populations evolved distinct life history characteristics in response to the diverse environments in which they were isolated after the last glaciation. Anthropogenic activities have resulted in a substantial decline (42% of the historical range is currently occupied; 28% is occupied by core [genetically unaltered] populations), but the number of extant populations, especially in headwater streams, has precluded listing of this taxon under the Endangered Species Act. Primary threats to persistence of Yellowstone cutthroat trout include (1) invasive species, resulting in hybridization, predation, disease, and interspecific competition; (2) habitat degradation from human activities such as agricultural practices, water diversions, grazing, dam construction, mineral extraction, grazing, timber harvest, and road construction; and (3) climate change, including an escalating risk of drought, wildfire, winter flooding, and rising temperatures. Extirpation of individual populations or assemblages has led to increasing isolation and fragmentation of remaining groups, which in turn raises susceptibility to the demographic influences of disturbance (both human and stochastic) and genetic factors. Primary conservation strategies include (1) preventing risks associated with invasive species by isolating populations of Yellowstone cutthroat trout and (2) connecting occupied habitats (where possible) to preserve metapopulation function and the expression of multiple life histories. Because persistence of isolated populations may be greater in the short term, current management is focused on isolating individual populations and restoring habitats; however, this approach implies that humans will act as dispersal agents if a population is extirpated because of stochastic events.

This book was released on 1963 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equilibrium yield of the cutthroat trout, Salmo clarki lewisi Girard, in Yellowstone Lake, Wyo., is determined from data on catch and spawning runs from 1945 to 1961. Changes in growth rate, spawning runs, mortality rates, and year-class strength are related to differences in total catch. Three stages of exploitation of the stock are defined and the maximum safe catch or equilibrium yield is estimated at 325,000 trout. Management of the sport fishery according to equilibrium yield is discussed with reference to regulations, distribution of fishing pressure, planting, and interspecific competition. The Yellowstone River fishery is treated briefly.

Available in PDF, EPUB and Kindle. Book excerpt: This beautiful and definitive guide brings together the world's lead leading expert on North American trout and salmon, Robert Behnke, and the foremost illustrator in the field, Joseph Tomelleri. North America is graced with the greatest diversity of trout and salmon on earth. From tiny brook trout in mountain streams of the Northeast, to cutthroat trout in the rivers of the Rockies, to Chinook salmon of the Pacific, the continent is home to more than 70 types of trout and salmon. How this came to be, how they are related, and what makes them unique -- and so breathtaking -- is the story of Trout and Salmon of North America. The more than 100 illustrations of trout and salmon by Joseph Tomelleri showcased here exhibit a genius for detail, coloration, and proportion. Each portrait is made from field notes, streamside observations, photographs, and specimens collected by the artist. The result is a set of the most accurate and stunning illustrations of fish ever created. Robert Behnke has distilled 50 years of his research and writing about trout and salmon in completing this book. No one understands better than Behnke the diversity and conservation issues concerning these fishes or communicates so lucidly the biological wonders and complexities of their particular beauty. Also included are more than 40 richly detailed maps that clearly show the ranges of populations of trout and salmon throughout North America. An irresistible delight for anyone who appreciates natural history, Trout and Salmon of North America is a master guide to the natural elegance of our native fishes.

Available in PDF, EPUB and Kindle. Book excerpt: This document focuses on the current status, distribution and range for five subspecies of cutthroat trout Oncorhynchus clarki, which are found largely on national forest system lands and ecosystems in the Rocky Mountain and Intermountain West within the U.S. from the Canadian to the Mexican border. The 5 subspecies -- Westslope, Yellowstone, Bonneville, Rio Grande, and Colorado River cutthroat trout -- are designated either species of special concern or sensitive. These subspecies are presently restricted to a fragment of their former range. Includes assessment methods, and origins and taxonomic theory. Illustrated.

Available in PDF, EPUB and Kindle. Book excerpt: Normal 0 The Yellowstone River within Yellowstone National Park is the world’s best Yellowstone Cutthroat Trout fishery. The Yellowstone River within the park can be divided into three-distinctive sections. The headwaters of the Yellowstone River begin on the east side of the Continental Divide from the Shoshone Mountain Range of Wyoming. The Yellowstone River flows northerly into Yellowstone Lake, elevation 7,733-feet. Yellowstone Lake is the largest lake at this elevation on the continent. The mid-section of the Yellowstone River, which flows out of Yellowstone Lake downstream to the Upper Falls of the Yellowstone River lies the world renown section of the Yellowstone River where hundreds of people flock to on July 15th “Opening Day” every year. The lower section, below the Lower Falls of the Yellowstone River flows through the Canyon of the Yellowstone downstream to the Yellowstone National Park Boundary, by the town of Gardner, Montana is probably the least fished section of the Yellowstone River. The fishing seasons opens July 15th every year which allows the Yellowstone Cutthroat Trout Brood Stock to spawn and gives the Yellowstone Cutthroat Fry time to emerge from the redds before the wade fishermen can step on them. The headwaters and mid-section of the Yellowstone River are the major spawning areas for the Yellowstone Lake Cutthroat Trout Fishery. The Yellowstone River is a premiere dry fly fishing river with prolific hatches of May Flies: Early Blue-Winged Olive (Baetis tricaudatus), Late Blue-Winged Olive (Baetis parvus), Little Western Blue-Winged Olive (Ephemerella margarita), Western Green Drake (Drunella grandis), Pale Morning Dun (Ephemerella inermis and Ephemerella infrequens) and Small Western Green Drake (Ephemerella flavilinea); Stone Flies: Salmon Fly (Pteronarcys californica), Western Big Golden Stone Fly (Calineuria californica), Western Medium Golden Brown Stone Fly (Isoperla sp.) and Little Yellow Stone Fly (Alloperla pallidula); Caddis: Green Sedge (Ryacophila sp.), Little Tan Short Horn Sedge (Glossosoma sp.), Spotted Sedge (Hydropsyche sp.) and Giant Orange Sedge (Dicosmoecus sp.).
