Download or read book The Imperiled Cutthroat written by Greg French and published by Patagonia. This book was released on 2016-05-16 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yellowstone, the world’s first national park and one of America’s truly great trout fisheries, has been a crucible for ideas on how to look after wild places. Renowned Australian fishing writer Greg French gives a sparkling firsthand account of how the park’s history, landscapes, wildlife, and people have touched anglers worldwide — and why this matters. The Imperiled Cutthroat is a travelogue that covers the story of the Yellowstone cutthroat trout: its discovery, biology, decimation, modern-day allure, and uncertain future. Although set against the dramatic backdrop of Yellowstone, comparisons to Australia, New Zealand, and Europe are inevitable. It is a cautionary tale too, ending up in Mongolia, which is as pristine as Montana once was. The Yellowstone fishery is at a crossroads, and debate about what to do is dangerously narrow. Anglers everywhere need to be constantly reminded that hatcheries are far from a panacea for ailing fisheries: fostering conservation of the natural environmental delivers far better outcomes at a fraction of the cost. The power of Greg’s stories comes not just from the quality of the writing but also from the quirks and passions of the people he meets. Greg's compelling storytelling enthralls anglers and naturalists the world over.
Download or read book Mortality Studies on Cutthroat Trout in Yellowstone Lake by Orville P Ball and Oliver B Cope written by Orville P. Ball and published by . This book was released on 1961 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a study of the Yellowstone Lake cutthroat trout, Salmo clarki lewisi, by the U.S. Fish and Wildlife Service, effects of environment on mortality of eggs, immature fish, spawners, and postspawners were measured for various components of the population in Yellowstone Lake (Wyoming). Five methods for estimating mortality of adults on spawning runs are described, with counting and tagging as the principal procedures. Of the total number of eggs deposited in the gravel, 60 to 75 percent died before hatching, and 99.6 percent had died by the time the fingerlings enetered Yellowstone Lake. In Arnica Creek runs, 48.6 percent died in the stream, 40.2 died later in the lake of natural causes, 7.6 were taken by fishermen, and 3.6 percent were alive 2 years later. The white pelican is a serious predator on cutthroat trout in Yellowstone Lake. From 1949 to 1953 fishermen caught 11.6 percent of the catchable trout available to them. Migrations of adult fish in Yellowstone Lake were traced through tagging.

Download or read book Equilibrium Yield and Management of Cutthroat Trout in Yellowstone Lake written by Norman Gustaf Benson and published by . 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.
Download or read book Fluctuations in Age Composition and Growth Rate of Cutthroat Trout in Yellowstone Lake written by Ross V. Bulkley and published by . This book was released on 1961 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Age composition, growth rate, and year-class strength of Yellowstone Lake cutthroat trout from collections made in 1948 and from 1950 to 1959 are analyzed to relate total catch changes in age composition and growth rate. An increase in growth rate of fish fully recruited to the fishery and a decrease in percentages of fish belonging to age groups VI and VII are attributed to an increase in fishing pressure. Mean age of the catch varied with year-length of the catch has remained high, suggesting that production is more efficient now than in past years. Maximum equilibrium yield may be near. If the catch continues to increase at the present rate, it may become excessive within the next few years.
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.

This book was released on 1963 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differences in hyoid teeth and spotting counts among samples from four related populations of Yellowstone cutthroat trout, Salmo clarki lewisi Girard, reached species and subspecies levels as defined by some workers. Body coloration varied significantly among fish in six spawning runs of Yellowstone Lake, Wyo. The use of coloration, spotting, and hyoid teeth counts in cutthroat trout for taxonomic purposes needs reevalution.

Available in PDF, EPUB and Kindle. Book excerpt: This history and guide to the fly-fishing waters of Yellowstone National Park is a loving homage to the region’s iconic wild trout. Yellowstone National Park is home to some of the most storied destinations in the history of fly fishing. Casting in the Firehole River is like going back in time to when bison roamed nearly every meadow in the West. Restored to their natal streams after near extinction, native Arctic grayling can once again be plucked from icy water at the foot of breathtaking waterfalls. Meanwhile, a daylong hike into true wild country rewards an angler with a chance to catch trophy native cutthroat trout on a lonely mountain lake. In Catching Yellowstone’s Wild Trout, local journalist and experienced angler Chris Hunt explores the rich history of these beloved and bountiful waters.
Download or read book Distribution Movements and Life history Characteristics of Yellowstone Cutthroat Trout Oncorhynchus Clarkii Bouvieri in the Upper Yellowstone River Drainage written by Brian Daniel Ertel and published by . This book was released on 2011 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distribution and abundance of Yellowstone cutthroat trout, Oncorhynchus clarkii bouvieri, has declined across the historic range because of anthropogenic influences. Habitat has been fragmented and non-native species have been introduced that compete with, feed upon, or interbreed with cutthroat trout. As a result, many cutthroat trout populations are now isolated in headwater streams and life-history forms are lost or reduced. The upper Yellowstone River basin, above Yellowstone Lake, offers a rare opportunity to study Yellowstone cutthroat trout in a large, intact, river system with few anthropogenic influences. Understanding of life-history forms present in the upper Yellowstone River basin assist in proper conservation and management of the watershed. To determine cutthroat trout life-history forms present, their abundance, and habitat preferences, a combination of radio-telemetry, electrofishing, underwater census, habitat assessment, and age and growth were used. Movements of 151 cutthroat trout were tracked by aircraft, 2003-2005. Most relocated fish (98%) followed a lacustrine-adfluvial life history migration pattern, spending an average 24 days in the river. Cutthroat began entering the river in April and most emigrated by August. Fish migrated as far as 67 km to spawn and spawning aggregations within the system were found in only 11 locations. Underwater census and electrofishing surveys were used to determine fish distribution and abundance in the Yellowstone River and its tributaries. Main stem cutthroat trout densities were low and not evenly distributed. A mean of 8 fish/500 m reach were sampled with the majority in 8 reaches. Juvenile (150 mm, 2 years old) and large adult (330 mm,4 years old) cutthroat trout were found in the main stem, but fish from 151-330 mm (age 3) were absent. Within tributaries, fish densities ranged from 1.7-49.5 fish/100 m reach. Fish up to 305 mm were sampled and ranged 1 to 4 years in age. Data from this study suggest most cutthroat trout in the upper Yellowstone River express a lacustrine-adfluvial life history, however, some fluvial fish are present in tributaries. These findings will be important in driving conservation and management decisions in this drainage and provide critical information in future ESA listing considerations.
