Available in PDF, EPUB and Kindle. Book excerpt: The brook trout of Great Smoky Mountains National Park are relatively scarce and are found only in remote, headwater streams. They are also small and short-lived. Males outnumber females, especially among sexually mature fish. The fecundity is lower than in fish of comparable size in Wisconsin and Canadian waters. Under present conditions, any increase in exploitation of the brook trout in the Park or damaging alteration of the habitat might have serious consequences for the remanent populations.

Download or read book Changes in Distribution of Trout in Great Smoky Mountains National Park, 1900-1977 written by George Alan Kelly and published by . This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant changes have occurred in the distribution of trout in streams of Great Smoky Mountains National Park since 1900. By the mid-1970's the original range of the native brook trout had been reduced by about 70% and the species was relegated to suboptimal habitat in head water streams. Most of the stream sections lost by brook trout became the territory of the introduced rainbow trout, which in 1977 occupied about 80% of the Park waters. After 1950, brown trout introduced in State waters outside the Park established reproducing populations in some 50 miles of stream formerly occupied only by rainbow trout. If current trends continue, the recovery of brook trout in Park water may be difficult, if not impossible, and brown trout may occupy much of the territory now held by rainbow trout.

Download or read book Brook Trout written by Nick Karas and published by Simon and Schuster. This book was released on 2015-11-03 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: North America has had a 400-year love affair with the brook trout - Salvelinus fontinalis- its great native trout. In this newly revised and updated volume, Nick Karas offers the only major profile of this most beautiful gamefish. Brook Trout is a thorough look at the history, biology, and angling possibilities of the fish most anglers affectionately call the brookie. Through the eyes of a trained ichthyologist, Karas explores the brook trout's biology and the events that led to its evolution and distribution. He unravels the controversies surrounding the two largest brook trout ever taken. But the core of this book is the fishery: its past status, current condition, and future. And because the history of brook trout fishing is inseparable from the history of American fishing, Karas follows the development of the rods, reels, lines, lures and flies that evolved as anglers pursued their fascination with this great game fish. Skyhorse Publishing is proud to publish a broad range of books for fishermen. Our books for anglers include titles that focus on fly fishing, bait fishing, fly-casting, spin casting, deep sea fishing, and surf fishing. Our books offer both practical advice on tackle, techniques, knots, and more, as well as lyrical prose on fishing for bass, trout, salmon, crappie, baitfish, catfish, and more. While not every title we publish becomes a New York Times bestseller or a national bestseller, we are committed to publishing books on subjects that are sometimes overlooked by other publishers and to authors whose work might not otherwise find a home.

Available in PDF, EPUB and Kindle. Book excerpt: Headwater species and peripheral populations that occupy habitat at the edge of a species range may hold an increased conservation value to managers due to their potential to maximize intraspecies diversity and species' adaptive capabilities in the context of rapid environmental change. The southern Appalachian Mountains are the southern extent of the geographic range of native Salvelinus fontinalis and naturalized Oncorhynchus mykiss and Salmo trutta in eastern North America. In this paper, we predicted distributions of these peripheral, headwater wild trout populations at a fine scale to serve as a planning and management tool for resource managers to maximize resistance and resilience of these populations in the face of anthropogenic stressors. We developed correlative logistic regression models to predict occurrence of brook trout, rainbow trout, and brown trout for every interconfluence stream reach in the study area. A stream network was generated to capture a more consistent representation of headwater streams. Each of the final models had four significant metrics in common: stream order, fragmentation, precipitation, and land cover. Strahler stream order was found to be the most influential variable in two of the three final models and the second most influential variable in the other model. Greater than 70% presence accuracy was achieved for all three models. The underrepresentation of headwater streams in commonly used hydrography datasets is an important consideration that warrants close examination when forecasting headwater species distributions and range estimates. Finally and additionally, it appears that a relative watershed position metric (e.g., stream order) is an important surrogate variable (even when elevation is included) for biotic interactions across the landscape in areas where headwater species distributions are influenced by topographical gradients.

Available in PDF, EPUB and Kindle. Book excerpt: The brook trout (Salvelinus fontinalis) is an iconic species among fly anglers and cold-water conservationists in eastern North America. This fish registers as a powerful symbol for its beauty and its imagery in art and literature. Its presence also tells us a great deal about the health of the larger environment. When an angler has a brook trout in hand, there is confidence that the water is close to pristine. Besides being an important indicator species, the brook trout, with its gold and reddish markings and its camouflaged green and black back, is one of the most beautiful freshwater fish in North America. And beyond the beauty of the fish itself, the environment in which it is found is also part of its past and present appeal. To fish for brook trout is often to fish in the last remote and rugged landscapes in the East, “fishscapes” that have not been polluted by stocking trucks that dump nonnative brown and rainbow trout in most of the East’s accessible cold waterways. Searching for Home Waters is part science, part environmental history, and part personal journey of the author, Michael K. Steinberg, and those he interviewed during his travels. The work takes a broad perspective that examines the status of brook trout in the eastern United States, employing a “landscape” approach. In other words, brook trout do not exist in a vacuum; they are impacted by logging, agriculture, fishing policies, suburban development, mining, air pollution, and climate change. Thus, while the book focuses specifically on the status and management of the brook trout—from Georgia to Labrador—it also tells the larger story of the status of the eastern environment. As a “pilgrimage,” this book is also a journey of the heart and contains Steinberg’s personal reflections on his relationship with the brook trout and its geography.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the linkages among physical and biological processes across scales is vital to understanding the diversity and heterogeneity of headwater streams. Most research investigating fish-habitat relationships in headwater catchments has been conducted over a limited geographic extent and at small spatial scales. We conducted spatially continuous single-pass electrofishing and physical stream habitat surveys, sampling all habitat units possible, within the fish-bearing portions of 16 catchments where coastal cutthroat trout were the only salmonid species present. Each catchment was surveyed twice, first in the autumn and then again the following spring, prior to the emergence of young-of-the-year cutthroat trout. Spatial and temporal (seasonal) variability of cutthroat trout abundance within each study catchment was assessed at coarse (catchment) and intermediate (stream segment) spatial scales. Catchment-scale cutthroat trout density in both the autumn and spring was positively correlated with catchment area, and significantly associated with catchment shape, with highest densities in heart-shaped catchments. These high densities may be associated with increased habitat heterogeneity imparted by tributary confluence effects, which tend to be greater in dendritic stream networks in heart-shaped catchments. Stream segments were identified and grouped by analyzing intermediate-scale stream channel characteristics (i.e., channel gradient and the location of significant tributary junctions) derived from high-resolution ([greater or less than] 2 m) LiDAR digital elevation models. Segment-scale fish density in the autumn was positively correlated with segment contributing catchment area, negatively correlated with channel gradient, and significantly associated with the interaction of the two variables (P 0.05). No segment-scale variables were significant predictors of fish density in the spring. The change in predictive ability for models of cutthroat density in the spring relative to the autumn was coupled with a significant decline in fish density between the seasons (P 0.05). Improved understanding of the relationships between fish abundance and stream habitat is needed to help land managers identify areas of high biological potential where specific habitat protection or restoration efforts may be warranted or most productive.
