This SSP project resulted in production of a thesis: Differences in oxygen consumption and critical oxygen levels of five stream fishes. Metabolic rate represents an integrated measure of a fish's physiology, particularly as it relates to stressors. A metric that is commonly used to determine the hypoxia tolerance of fishes is the determination of animal oxygen consumption rate (MO2), which is thought to reflect the ability of an organism to extract oxygen from the environment to maintain routine metabolic rate as dissolved oxygen (DO) decreases. We used respirometry to quantify the influence of two abiotic factors as potential stressors on stream fishes: temperature and dissolved oxygen. We determined standard...

A draft report and supporting information was produced by this SSP project. A scoping and reconnaissance study was conducted by the US Geological Survey in cooperation with the US Fish and Wildlife Service and National Park Service. Sediment, surface water and pore water samples were collected at 21 sites in the Clinch, Powell and South Fork Cumberland River basins in 2004-05. Three coal ponds (one yard sump and two drying cells) were also sampled in 2005. Surficial streambed sediment ranged from 0 to 47.7 percent coal and was composed predominantly of sand and gravel. Sediment quality guidelines were periodically exceeded at several sites for arsenic, chromium, lead and 22 of 31 polycyclic aromatic hydrocarbons...

This SSP project produced a Final Report and two publications. Carey, C.S., J.W. Jones, R.S. Butler, E.M. Hallerman. 2015. Restoring the endangered oyster mussel (Epioblasma capsaeformis) to the upper Clinch River, Virginia: an evaluation of population restoration techniques. Restoration Ecology. DOI: 10.1111/rec.12195. From 2005 to 2011, the federally endangered freshwater mussel Epioblasma capsaeformis (oyster mussel) was reintroduced at three sites in the upper Clinch River, Virginia, using four release techniques. These release techniques were (1) translocation of adults (site 1, n=1418), (2) release of laboratory-propagated sub-adults (site 1, n=2851), (3) release of 8-week-old laboratory-propagated juveniles...
