This book was released on 2019 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to improve habitat for fish, particularly salmonids, have a long history and intervention is extensive and ongoing. Resource managers and practitioners spend considerable time and money implementing stream habitat projects. Installation of artificial habitat structures is a consistently popular approach. In this thesis I describe effects of artificial structures on stream morphology and fish density and highlight management implications. In the first chapter, I address the effects of habitat structures on stream morphology in a low-power system. Formal evaluations of the effects of habitat structures on stream morphology in low-power systems like the North Branch of the Au Sable River have been very limited relative to the popularity of these projects. I demonstrate that while artificial structures produce some desired habitat characteristics, their effects tend to be localized and may be outweighed by deposition. In the second chapter, I evaluate the relationship between the density of Brown Trout (Salmo trutta) and Brook Trout (Salvelinus fontinalis) relative to the density of artificial structures. While there are significant relationships for both species, responses are highly variable, and differ by species and size in relation to structure type. I also show the influence of stream context on relationships between fish and artificial structures.

This book was released on 2008 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrologic processes impact the functioning of aquatic ecosystems and influence fish population dynamics. The flow regime of a stream affects the structure, composition, and productivity of fish communities by regulating abiotic habitat conditions and biotic community processes. In the Great Smoky Mountains National Park (GRSM), native brook trout (Salvelinus fontinalis) populations have declined in some watersheds over the past decade, believed to be primarily due to episodic acidification. The potential affects long-term hydrologic patterns, temporal hydrologic trends, and hydrologic extremes have on brook and rainbow trout (Oncorhynchus mykiss) populations were explored in this study. The current GRSM fish sampling program began nearly two decades ago; a total of 69 streams, including 369 sites, are routinely sampled by GRSM fisheries biologists with standard methods. Detailed data is collected on the trout populations. The Nature Conservancy's Indicators of Hydrologic Alteration (IHA) was used to quantify the flow regime of each stream into 67 ecological relevant parameters. Because the trout sites were located in remote ungaged streams, the Hydrologic Simulation Program FORTRAN (HSPF) was used to simulate flows at each trout site for a study period lasting 18 years (1990-2007). Using local climate data the model was calibrated by adjusting parameters including storage, infiltration, runoff, and ground water for three elevation classes (low
Book Synopsis Sensitivity and Exposure of Brook Trout Salvelinus Fontinalis Habitat to Climate Change by :
Download or read book Sensitivity and Exposure of Brook Trout Salvelinus Fontinalis Habitat to Climate Change written by and published by . This book was released on 2010 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicting coldwater fisheries distributions under various climate scenarios is of interest to many fisheries managers and researchers. Larger scale models have been useful in highlighting the potential large scale threat. However, the error associated with these models makes predictions of the persistence of individual cold water fisheries problematic. Most of this error is associated with predicted air and water temperatures which typically are simple elevation and location (latitude/longitude) models with simple caveats such as 1°C increase in air temperature equals 0.8°C increase in water temperatures. I directly measured paired air and water temperatures in watersheds containing reproducing populations of brook trout in Virginia during the critical summer period (July 1 to September 30) in both 2009 and 2010. I developed a classification system using sensitivity (change in the daily maximum water temperature from a 1°C increase in the daily maximum air temperature) and exposure metrics (frequency; duration; and magnitude of daily maximum water temperatures> 21°C) that classified brook trout populations into four categories: High Sensitivity-High Exposure; High Sensitivity-Low Exposure; Low Sensitivity-High Exposure and Low Sensitivity- Low Exposure. I found that my paired air and water temperature relationships were highly variable among sites and were a useful metric for classifying the sensitivity and exposure of individual brook trout populations to various climate change scenarios. I identified many (25%) Low Sensitivity- Low Exposure brook trout populations that appear to be resilient to climate change. The median sensitivity (0.39°C) in this study was much lower than the assumed rate (0.80°C) used in many regional models that predicted a complete extirpation of brook trout in Virginia. Several GIS generated metrics (sample area; % riparian canopy; solar insolation ; % groundwater; elevation; % watershed in forest cover) were useful for predicting (accuracy approximately 75%) sensitivity and exposure values. Directly measuring paired air and water temperature relationships can reduce the error of large scale models. I recommend that managers making investment decisions in protecting and restoring brook trout use my direct measurement approach when they cannot afford to make a Type I or Type II error.

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.
