Sport Fish Consumption Advisory For West Virginia, William Alvin Warnick
Sport Fish Consumption Advisory For West Virginia, William Alvin Warnick
Graduate Theses, Dissertations, and Problem Reports
The risk based sport fish consumption advisory protocol, West Virginia Sport Fish Consumption Advisory Guide (the Guide), was drafted for the state. Fish were collected from ten West Virginia sites (5 previously identified as contaminated, 5 previously identified as uncontaminated). Fish samples were collected, processed and analyzed for total mercury concentration and Aroclors (PCBs). Recommended meal frequencies were calculated from contaminant levels and based on the Guide. Mean fillet sample contaminant levels were compared to composite sample levels and found to require the same level or in one case a more protective of consumption advisory. Ten composite samples had Aroclor …
Combined Effects Of Water Chemistry, Canopy Cover, And Stream Size On Benthic Macroinvertebrates Along A Central Appalachian Stream Continuum, Jesse Adam Bopp
Combined Effects Of Water Chemistry, Canopy Cover, And Stream Size On Benthic Macroinvertebrates Along A Central Appalachian Stream Continuum, Jesse Adam Bopp
Graduate Theses, Dissertations, and Problem Reports
I sampled benthic macroinvertebrates along a 25.2 km stream continuum in the Central Appalachian Mountains of West Virginia from May---October 2000. Six components of macroinvertebrate community structure and function were measured: density, biomass, richness, community taxa similarity, feeding group composition, and metric composition. I quantified these components to determine if localized variation in alkalinity and canopy cover would modify stream continuum predictions. Localized variation in alkalinity and canopy cover significantly affected macroinvertebrate structure and function and modified stream continuum predictions. Results indicated that alkalinity was the primary determinant of macroinvertebrate structure and function, and that the effects of canopy cover …
Geology, Surface Hydrology, And Fish Habitat Relationships In The Upper Shavers Fork Drainage Basin, West Virginia, Ryan Cooley Gaujot
Geology, Surface Hydrology, And Fish Habitat Relationships In The Upper Shavers Fork Drainage Basin, West Virginia, Ryan Cooley Gaujot
Graduate Theses, Dissertations, and Problem Reports
Shavers Fork is the mainstem stream of a unique upper elevation watershed located in the Appalachian Plateaus province of West Virginia. Surficial "facies" mapping of in-stream and floodplain-adjacent landforms helped to classify small-scale flow patterns into heterogeneous and homogeneous channel units. Channel-unit bankfull width, channel-unit length, channel-unit area, and channel-unit depth all increase in the downstream direction. Riffles constitute 32 percent of the total channel unit area, riffle-run complexes and glides make up 26 percent each, bluff-pool complexes constitute 7 percent, riffle-glide complexes 6 percent, and true pools make up only 2 percent. Upper reaches contain the most in-stream and …
Spatial Population Dynamics Of Brook Trout (Salvelinus Fontinalis) In A Central Appalachian Watershed, Peter John Lamothe
Spatial Population Dynamics Of Brook Trout (Salvelinus Fontinalis) In A Central Appalachian Watershed, Peter John Lamothe
Graduate Theses, Dissertations, and Problem Reports
I examined the spatial population dynamics of brook trout (Salvelinus fontinalis) in a central Appalachian watershed. The objectives of my research were: (1) identify factors that influence reproduction; (2) determine if factors that influence reproduction influence the distribution and abundance of juvenile and adults; and (3) to determine if the spatial arrangement of stream habitat influence growth, residency, and population fluctuation rates. I used visual surveys and redd counts to quantify spatial variation in habitat quality and brook trout spawning activity. I conducted a mark-recapture study over four seasons to quantify population parameters. The results of my research show that: …
Overwintering Abundance And Distribution Of Striped Bass (Morone Saxtilis) In The Hudson River Estuary Using Hydroacoustic Techniques, Brian William Nagy
Overwintering Abundance And Distribution Of Striped Bass (Morone Saxtilis) In The Hudson River Estuary Using Hydroacoustic Techniques, Brian William Nagy
Graduate Theses, Dissertations, and Problem Reports
Using a modification of standard techniques, a target strength to length relationship was developed for white perch (Morone americana) and striped bass (Morone saxtilis). This target strength to length relationship was compared to two standard relationships (Love and Foote). The calculated relationship was not found to be significantly different from Love's equation, but was different from Foote's equation. This calculated relationship was applied to hydroacoustic data collected on the Hudson River in December of 1995 and 1997. The goal of the hydroacoustic data collection was to assess the abundance and distribution of overwintering Hudson River striped bass. Results from this …
