This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adirondack brook trout (Salvelinus fontinalis) depend on locations of groundwater upwelling for spawning, nursery habitat and thermal refugia for both young-of-year (YOY) and adult fish. Landscape-scale anthropogenic disturbances, such as logging and road construction, have the potential to influence brook trout habitat by altering these groundwater regimes. We used a topographic index (TI) approach to link watershed-scale topography with groundwater-influenced tributaries and seeps and YOY brook trout presence in the littoral zone of three lakes in the Adirondack Mountains, NY. The TI value of shoreline locations was positively associated with the temperature difference between lake surface and substrate, indicating greater groundwater seepage at locations with a higher TI value. The TI value of shoreline locations was also positively correlated with YOY brook trout presence in the nearshore zone. TI represented a significant improvement in predictive capability over currently available groundwater-influenced habitat location and delineation methods. Akaike's information criterion indicated that TI value was the strongest predictor of: (1) the presence of groundwater-influenced tributaries or seeps, and (2) YOY brook trout presence and numerical abundance in the nearshore zone. However, TI-based metrics were unable to predict brook trout population reproductive status or density at an inter-lake scale, possibly because the effects of acid precipitation are the primary drivers of variability in brook trout population abundance at a regional scale within the Adirondacks. The TI model represents a useful management tool at the scale of an individual lake shoreline, but further refinement is required for applications at an inter-lake scale.

This book was released on 1993 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: We address the significance of changes in summer thermal stratification patterns of Adirondack lakes affected by acidification to cold-water fish populations inhabiting these sensitive lakes. The brook trout (Salvelinus fontinalis) is the primary cold-water fish species indigenous to acid-sensitive lakes in the Adirondack region of northern New York State; the ability of these lakes to sustain this important sport species is highly dependent on the availability of adequate summer habitat, consisting of cool, well-oxygenated water. We hypothesized that acidification-induced reductions in the thermal stability of sensitive Adirondack lakes could lead to degradation of potential brook trout habitat. We also hypothesized, on the basis of energetic considerations, that brook trout growth and average size at age would be sensitive indicators of differences in the extent and availability of preferred summer habitat in lakes with different thermal structures. These hypotheses were addressed in this study by utilizing data available from previous lake liming studies in the Adirondack region, brook trout growth data from management studies in the region, and the extensive Adirondack Lake Survey Corporation (ALSC) data base. We compared brook trout growth among lakes with known thermal stratification patterns; analyzed temporal changes in the extent and availability of preferred brook trout habitat, resulting from changes in acid or base status of limed Adirondack lakes; and applied a bioenergetic growth model for sensitivity analysis of temperature effects on simulated growth of brook trout populations inhabiting lakes with different thermal structures.
Book Synopsis A Mid-Atlantic Stream Suitability Index for Brook Trout (Salvelinus Fontinalis) by : Albert Kirk Smith
Download or read book A Mid-Atlantic Stream Suitability Index for Brook Trout (Salvelinus Fontinalis) written by Albert Kirk Smith and published by . This book was released on 2011 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Mid-Atlantic multimetric index provides a quick and cost effective assessment of brook trout streams or potential brook trout streams in the Mid-Atlantic United States. Using five core metrics--three in-stream metrics (riffle/run quality, dissolved oxygen content and water temperature) and two watershed metrics (percent land use in agriculture and distance to the nearest road from the survey site), the index can be calculated in the field by professional natural resource managers or trained volunteers. The index should be used in concert with other assessment tools, including a classification model designed to allow resource managers to quickly screen a given stream reach in order to determine its potential for supporting sustainable populations of brook trout. Used in tandem, the classification model could provide a preliminary assessment of a stream, followed by a secondary assessment using an index rating to further evaluate stream quality and potential.

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.
