Detection of Aeromonas salmonicida from water using a filtration method Detection of Aeromonas salmonicida from water using a filtration method
Aeromonas salmonicida is a principal pathogen that contributes to mortality in hatchery-maintained Atlantic salmon that originated from the Connecticut and Merrimack rivers in the northeastern United States. Field tests were conducted to assess a filtration method for detection of A. salmonicida in water used to rear fishes. A presumptive identification of typical A. salmonicida was...

Loma sp. salmonids from the Eastern United States: Associated lesions rainbow trout Loma sp. salmonids from the Eastern United States: Associated lesions rainbow trout
A microsporidian of the genus Loma was noted in the gills of rainbow trout Oncorhynchus mykiss from a state hatchery (Buford Trout Hatchery) in Georgia. Mortalities of varying severity occur at this hatchery every fall, and the microsporidian was noted during an experiment from August 1991 to January 1992 to determine the effects of water source on disease. Infections first appeared to...

Survival rates of American woodcock wintering along the Atlantic coast Survival rates of American woodcock wintering along the Atlantic coast
Because American woodcock (Scolopax minor) populations have been declining, we attached radio transmitters to woodcock at coastal plain sites to determine if survival during winter was involved in the decline. Sites were in Georgia (1982-84, 1989-92), South Carolina (1988-89), and Virginia (1991-92). Survival rates were not different between age or sex classes. Survival rates differed (P...

Water and sediment budgets for the stormwater-drainage channel at the Navy Ships Parts Control Center near Mechanicsburg, Pennsylvania, water year 1993 Water and sediment budgets for the stormwater-drainage channel at the Navy Ships Parts Control Center near Mechanicsburg, Pennsylvania, water year 1993
The Navy Ships Parts Control Center near Mechanicsburg, Pa., occupies an area of 824 acres, of which 358 are covered by impervious surfaces. Most of the impervious area is drained by stormwater systems that discharge to an open channel that extends about 7,900 feet from its headwaters to its confluence with Trindle Spring Run. The channel drains an area of 992 acres, of which 435 are...

Hydrogeology, herbicides and nutrients in ground water and springs, and relation of water quality to land use and agricultural practices near Carlisle, Pennsylvania Hydrogeology, herbicides and nutrients in ground water and springs, and relation of water quality to land use and agricultural practices near Carlisle, Pennsylvania
Discharge and water-quality data collected in two adjacent karst-spring basins in Cumberland County, Pa., from May 1990 through April 1991 were used to (1) describe the hydrogeology of the area; (2) determine the concentrations of selected herbicides, herbicide-soil metabolites, and nutrients in water from wells and discharges from springs, (3) determine herbicide and nutrient discharges...

The computer model Hydrotherm, a three-dimensional finite-difference model to simulate ground-water flow and heat transport in the temperature range of 0 to 1,200 degrees C The computer model Hydrotherm, a three-dimensional finite-difference model to simulate ground-water flow and heat transport in the temperature range of 0 to 1,200 degrees C
Quantitative modeling of the deep parts of magmatic- hydrothermal systems has been limited by the lack of publicly available, documented computer models for multiphase, high-temperature flow. This report documents HYDROTHERM, a finite-difference model for three-dimensional, multiphase flow of pure water and heat over a temperature range of 0 to 1,200 degrees Celsius and a pressure range...

Two hybrid common x roseate terns fledge at Falkner Island, Connecticut Two hybrid common x roseate terns fledge at Falkner Island, Connecticut
Although these two similarly-sized species are sympatric throughout much of their breeding range, there are few published records of hybridization between Roseate (Sterna dougallii) and Common (S. hirundo) Terns. Records include at least five from Europe (Witherby and Ticehurst 1908, Perry 1972, Robbins 1974, Burggraeve 1977, van den Berg 1980) and only one from North America (Hays 1975)...
