Water quality of large discharges from mines in the anthracite region of eastern Pennsylvania Water quality of large discharges from mines in the anthracite region of eastern Pennsylvania
In 1991, 99 of the 102 coal mines in the anthracite coal fields of Pennsylvania that discharged 1.0 cubic foot per second or more when water-quality samples were collected in 1975 were revisited. Water was not discharging from 15 of these 99 mines in 1991. Discharge, water temperature, specific conductance, pH, dissolved oxygen, sulfate, iron, manganese, alkalinity, and acidity were...

Factors affecting phosphorus transport at a conventionally-farmed site in Lancaster County, Pennsylvania, 1992-95 Factors affecting phosphorus transport at a conventionally-farmed site in Lancaster County, Pennsylvania, 1992-95
The U.S. Geological Survey and the Bureau of Land and Water Conservation of the Pennsylvania Department of Environmental Protection conducted a cooperative study to determine the effects of manure application and antecedent soil-phosphorus concentrations on the transport of phosphorus from the soil of a typical farm site in Lancaster County, Pa., from September 1992 to March 1995. The...

Quality of ground water at selected sites in the upper Mahoning Creek Basin, Pennsylvania Quality of ground water at selected sites in the upper Mahoning Creek Basin, Pennsylvania
The ground-water quality of the upper Mahoning Creek Basin is largely unknown. Human activities in the basin have altered much of the landscape. The presence of coal mining, oil and gas exploration, agriculture, on-lot septic systems, and commercial development within the basin can introduce contaminants altering the natural chemistry of the ground water. Data collected to document...

Effects of growth hormone and insulin-like growth factor I on salinity tolerance and gill Na+, K+ and -ATPase in Atlantic salmon (Salmo salar): Interaction with cortisol Effects of growth hormone and insulin-like growth factor I on salinity tolerance and gill Na+, K+ and -ATPase in Atlantic salmon (Salmo salar): Interaction with cortisol
The potential roles of growth hormone (GH) and insulin-like growth factor I (IGF-I) in seawater (SW) acclimation of juvenile Atlantic salmon (Salmo salar) were examined. Compared to controls, fish in 12 ppt seawater given one or three injections (2–6 days) of GH (ovine, 0.2μg · g−1) or IGF-I (recombinant bovine, 0.05–0.2μg · g−1) had significantly greater salinity tolerance as judged by...

Gas-phase axial dispersion in a spray tower Gas-phase axial dispersion in a spray tower
Gas-phase axial dispersion (mixing of the composition of the gas phase along the longitudinal axis) was characterized in an enclosed spray tower for purposes of establishing reactor type for the solute-solvent pair oxygen and water. Test condition variables were spray tower height (TH), 1·52, 2·03 and 2·54 m; hydraulic loading (HL), 44·2, 66·3 and 88·4 kg/m2s; the ratio of volumetric...

Feeding trials with juvenile Atlantic sturgeons propagated from wild broodstock Feeding trials with juvenile Atlantic sturgeons propagated from wild broodstock
Juvenile Atlantic sturgeons Acipenser oxyrinchus produced by hormone‐induced spawning of wild broodstock from the Hudson River, New York, were used in a diet study. Fish fed live Artemia sp. as first‐feeding fry for 35 d were observed to convert readily to formulated diets. At 79 d posthatch, four formulated feeds were offered: sturgeon starter 9304, Biokyowa, Zeigler esocid diet, and...

Monitoring for early detection of Aeromonas salmonicida to enhance antibiotic therapy and control furunculosis in Atlantic salmon Monitoring for early detection of Aeromonas salmonicida to enhance antibiotic therapy and control furunculosis in Atlantic salmon
Juvenile Atlantic salmon Salmo salar at the White River National Fish Hatchery were monitored quarterly for Aeromonas salmonicida, the etiologic agent of furunculosis. Samples were obtained in August, November, January, and March, within an 8‐month smolt production cycle during 1992–1993. Aeromonas salmonicida was isolated in August from external mucus and kidneys of fish within six...
