Nitrogen and phosphorus balance of grass carp, Ctenopharyngodon idella, fed elodea, Egeria denea
J.G. Stanley
1974, Transactions of the American Fisheries Society (103) 587-592
The herbivorous grass carp fed winter elodea exhibited a negative nitrogen balance in metabolism, suggesting that food having a higher protein content would be required for normal growth. About a third of the phosphorus contained in food was retained; hence, a combination of aquatic plants and grass carp might afford...

Immature insects (Plecoptera, Trichoptera, and Ephemeroptera) collected from deep water in western Lake Superior
James H. Selgeby
1974, Journal of the Fisheries Research Board of Canada (31) 109-111
Five species of aquatic insects - two plecopterans, two trichopterans, and one ephemeropteran - usually found in streams or ponds were collected in water 32-100 m deep in western Lake Superior. All appear to be new records for the lake and all were collected from far greater depths than previously...
Preliminary map showing availability of ground water from major glacial-drift aquifers in Griggs and Steele Counties, North Dakota
Joe S. Downey
1974, Open-File Report 74-1023
This investigation is part of a statewide program to determine the location, extent, and hydrologic characteristics of the ground-water reservoirs (aquifers).The investigation was made cooperatively by the U.S. Geological Survey, North Dakota State Water Commission, North Dakota Geological Survey, and Griggs and Steele Counties Water Management Districts.This preliminary map is...
Seismic risk maps

Robert Mallis, editor(s)
1974, Earthquake Information Bulletin (USGS) (6) 10-15
What is the possibility that an earthquake will occur near you? Have you ever wondered what the chances were that an earthquake could affect you at home or at work? Perhaps you are planning to move to a part of the country subject to frequent earthquakes. How do you determine...

Various fish species as biological control agents for the dark rice field mosquito in Arkansas rice fields
R. B. Davey, M. V. Meisch, D. L. Gray, J. M. Martin, Kermit E. Sneed, F. J. Williams
1974, Environmental Entomology (3) 823-826
During the summers of 1972–73, 10 fish species were evaluated as predators against larvae of the dark rice field mosquito, Psorophora confinnis (Lynch-Arribalzaga), near Stuttgart, Ark. Stocking rates were 0.02, 0.03, and 0.06 fish/ft 2 . At the lowest stocking rate green sunfish, Lepomis cyanellus Rafinesque, reduced larval numbers by 89.7% and were significantly more effective...
Teleseismic studies indicate existence of deep magma chamber below Yellowstone National Park
H. M. Iyer
1974, Earthquake Information Bulletin (USGS) (6) 3-7
The secrets of Yellowstone National Park's spectacular geysers and other hot water and steam phenomena are being explored by the U.S Geological Survey with the aid of distant earthquakes (teleseisms). For some time geologists have known that the remarkable array of steam and hot water displays, for which the park...
Relationships between chemical structure and rat repellency. II. Compounds screened between 1950 and 1960
W.A. Bowles, V. A. Adomaitis, J.B. DeWitt, J.J. Pratt Jr.
1974, Report
Over 4,600 compounds, chiefly organic types, were evaluated using both a food acceptance test (Part A) and a barrier penetration bioassay (Part B), to correlate relationships between chemical structure and rodent repellency.These chemicals are indexed and classified according to the functional groups present and to the degree of substitution within...
PCB's and p,p'DDE in the blood of cachectic patients
Robert J. Hesselberg, David D. Scherr
1974, Bulletin of Environmental Contamination and Toxicology (11) 202-205
The pheasant, in its North American range, seems to have had its greatest success in glaciated or in other areas associated with calcareous soils. Success has been slight in areas deficient in calcium.....In Lancaster County, Pennsylvania, no environmental difference other than presence or absence of limestone was discovered that might...
Invertebrate macrobenthos of Lake Oahe, 1968-69
William E. Jones, James H. Selgeby
1974, Technical Paper 73
The benthos in Lake Oahe, as determined from about 450 bottom samples collected during the open water season in 1968 and 1969, was dominated by oligochaetes and chironomids; Caenis (Ephemeroptera) and Chaoborus (Diptera) were occasionally abundant. Total benthos was estimated at 3,600 organisms/mA? with an ash-free dry weight of about...
An experimental trap net fishery, Lake Oahe, South Dakota, 1965
James A. Gabel
1974, Technical Paper 82
Large trap nets were evaluated as a commercial gear for capturing buffalo fish during July-September 1965. During the 72-day fishing period, 13,171 fish weighing 21,669 kg were taken. Bigmouth buffalo (Ictiobus cyprinellus) and smallmouth buffalo (Ictiobus bubalus) dominated the catch (78.2% by weight). Eight sport species accounted for 3.6% of...
