Detection of infectious haematopoietic necrosis virus in river water and demonstration of waterborne transmission
D. Mulcahy, R.J. Pascho, C.K. Jenes
1983, Journal of Fish Diseases (6) 321-330
In a study of the possible role of waterborne infectious haematopoietic necrosis virus in transmission of the disease among spawning sockeye salmon, Oncorhynchus nerka (Walbaum), both infection rates and virus titres were higher in fish held at high density in a side channel than in fish in the adjacent river....
Mortality due to infectious hematopoietic necrosis of sockeye salmon (Oncorhynchus nerka) fry in streamside egg incubation boxes
D. Mulcahy, R.J. Pascho, C.K. Jenes
1983, Canadian Journal of Fisheries and Aquatic Sciences (40) 1511-1516
Infectious hematopoietic necrosis virus caused mortality of sockeye salmon (Oncorhynchus nerka) in streamside egg incubation boxes. Virus was not detectable in eggs or alevins; its first isolation coincided with the appearance of dead fish in a trap on the outflow from the box. Mortality due to the virus did not...
Titre distribution patterns of infectious haematopoietic necrosis virus in ovarian fluids of hatchery and feral salmon populations
D. Mulcahy, R.J. Pascho, C.K. Jenes
1983, Journal of Fish Diseases (6) 183-188
Infectious haematopoietic mecrosis virus (IHNV) is enzootic in virtually all populations of sockeye salmon, Oncorhynchus nerka (Walbaum), and in populations of chinook salmon, O. tshawytscha (Walbaum), of the Sacramento River drainage in California. This disease is an obstacle in hatcheries using brood stocks from these populations. However, naturally spawning sockeye...
Effect of loading density of sockeye salmon, Oncorhynchus nerka (Walbaum), eggs in incubation boxes on mortality caused by infectious haematopoietic necrosis
D. Mulcahy, K. Bauersfeld
1983, Journal of Fish Diseases (6) 189-193
Infectious haematopoietic necrosis (IHN) can cause massive mortalities of sockeye salmon, Oncorhynchus nerka (Walbaum), cultured in hatcheries. One method of enhancing sockeye salmon populations is to use a streamside egg incubation box from which the fry are automatically released into the stream as they emerge from the gravel. In this...
Retention of infectious haematopoietic necrosis virus infectivity in fish tissue homogenates and fluids stored at three temperatures.
J. Burke, D. Mulcahy
1983, Journal of Fish Diseases (6) 543-547
Pools of brain, kidney, spleen, liver and gut tissues from several rainbow trout, Salmo gairdneri Richardson, and whole sockeye salmon, Oncorhynchus nerka (Walbaum), fry were homogenized with a known amount of infectious haematopoietic necrosis virus (IHNV). Virus was also added to ovarian fluids and sera pooled from several rainbow trout....

Ground-water resources and geology of Dodge County, Wisconsin
R.W. DeVaul, C.A. Harr, J.J. Schiller
1983, Wisconsin Geological & Natural History Survey Information Circular 44
The ground-water resources of Dodge County were evaluated to aid planners in meeting the needs resulting from growth in population and industry. The sand-and-gravel, Silurian dolomite, Galena-Platteville, and sandstone aquifers are the principal sources of ground water. Probable well yields from the sand- and-gravel aquifer and the Galena-Platteville aquifer range...
Trends in ground-water levels in Wisconsin through 1981
R.M. Erickson, R. D. Cotter
1983, Wisconsin Geological & Natural History Survey Information Circular 43
Hydrographs of ground-water levels in Wisconsin display fluctuations in the potentiometric surface of confined and unconfined aquifers. The graphs are plotted from periodic (weekly or monthly) measurements and from continuous recording gage records. Two hundred and ten hydrographs having periods of record of at least 5 years between 1934 and...

Reconnaissance of ground water in vicinity of Wichita Mountains southwestern Oklahoma
John S. Havens
1983, Circular 85
Urbanization and industrial growth have increased demands on water supplies in the vicinity of the Wichita Mountains in southwestern Oklahoma. The principal city, Lawton, uses surface water, supplemented by small quantities of ground water from the Arbuckle Group (Cambrian-Ordovician), for industrial and recreational use. During periods of drought, surface-water supplies...

Geohydrologic framework of the Roswell ground-water basin, Chaves and Eddy Counties, New Mexico
G. E. Welder
1983, Technical Report 42
This report describes the geohydrology of the Roswell ground-water basin and shows the long-term hydrostatic-head changes in the aquifers. The Roswell ground-water basin consists of a carbonate artesian aquifer overlain by a leaky confining bed, which, in turn is overlain by an alluvial water-table aquifer. The water-table aquifer is hydraulically...
Reconnaissance of the quality of surface water in the Weber River basin, Utah
Kendall R. Thompson
1983, Technical Publication 76
This report on the reconnaissance of surface-water quality in the Weber River basin was prepared by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The purposes of the reconnaissance were: (1) To obtain information on the general inorganic chemical characteristics of...

We installed a precise geodetic network along the San Andreas fault near Pearblossom, California in November, 1980. The network is within the region frequently referred to as the "Palmdale Uplift" and consists of 13 lines radiating from a central benchmark. The lines range in length from 3.2 to 8.1 km...

1983, Journal of Great Lakes Research (9) 403-420
Nutrient additions by the atmosphere and six tributaries to nearshore waters of northwestern Lake Huron were measured at weekly intervals from August 1975 to July 1976. The atmosphere contributed 43% of the nitrogen (N) and 10% of the phosphorus (P) that was added during the year. The 1975–76 atmospheric loading...
13C NMR spectral characterization of epimeric rotenone and some related tetrahydrobenzopyranofurobenzopyranones
S. L. Abidi, M.S. Abidi
1983, Journal of Heterocyclic Chemistry (20) 1687-1692
The 13C nuclear magnetic resonance (nmr) spectra of epimers of rotenone and four 12a-hydroxy-analogues were examined to determine the stereochemical effect of the B/C ring fusion involving the 6a- and 12a-carbon centers. Chemical shift differences between the epimeric carbon resonances of cis- and trans-6a,12a-compounds were notably larger than those of...
