First-year growth of the walleye, Stizostedion vitreum vitreum (Mitchill), and associated factors in the Red Lakes, Minnesota
Lloyd L. Smith Jr., Richard L. Pycha
1960, Limnology and Oceanography (5) 281-290
First-year growth of the walleye, Stizostedion vitreum vitreum (Mitchill), was studied from 4,544 fish collected during the first summer of life in the Red Lakes in six seasons and from back calculations on 4,474 fish one year or more in age representing 17 year classes. Sexes did not differ in growth rate....
Age and growth of the whitefish Coregonus clupeaformis, of Munising Bay, Lake Superior
Thomas A. Edsall
1960, Transactions of the American Fisheries Society (89) 323-332
This study is based on a sample of 415 whitefish collected in 1953 from an unexploited population in Munising Bay, Lake Superior. Gill-net and trawl catches had different length-frequency distributions and age compositions, but estimates of growth from the two catches were very similar. The body-scale relation is...
The American Fisheries Society
James W. Moffett
1960, U.S. Trout News (5) 20-22
In the course of studies designed to determine the calcium and phosphorus requirements of breeding bobwhite quail, it was found that best results were obtained when the Ca/P ratio in the diet was approximately 2.3:1. Variations in the Ca/P ratio produced significant differences in results when the level of...
Water and the Southwest
Luna Bergere Leopold
1960, Landscape (10) 27-31
In a pluvial period associated with Wisconsin glaciation the closed basin of the Estancia valley in New Mexico held a lake which, at its maximum extent, was 150 feet deep and had a surface area of 450 square miles. This basin, with an elevation of about 6,000 feet, has at...
Core logs from five test holes near Kramer, California
William K. Benda, Richard C. Erd, Ward C. Smith
1960, Bulletin 1045-F
In 1957, five test holes were drilled near Kramer, Calif., in the western Mojave Desert, for the U.S. Geological Survey. The drill sites are in topographic basins where gravimetric and geologic surveys indicated the presence, beneath alluvium, of a thick section of Quaternary and Tertiary sedimentary and volcanic rocks.Two holes,...
Effect of FeS on the unit cell edge of sphalerite, a revision
Brian J. Skinner, P. B. Barton Jr., G. Kullerud
1959, Economic Geology (54) 1040-1046
Redeterminations of the relation between the composition and unit-cell size of Fe-bearing sphalerites, necessitated because of partial oxidation of the FeS sample used in earlier measurements, are presented. It is noted that the Fe-ZnS solvus curve may also require revision and should be used with caution, particularly for temperature determinations...
Dry diets for Chinook salmon
Walter E. Neilson, J. J. Mazuranich
1959, Progressive Fish-Culturist (21) 86-88
The purpose of this paper is to present the results obtained with seven different diets used as starting diets of chinook salmon fry....
Etiology of sockeye salmon 'virus' disease
Raymond W. Guenther, S.W. Watson, R.R. Rucker, A. J. Ross
1959, Special Scientific Report - Fisheries 296
Violent epizootics among hatchery reared sockeye salmon fingerlings (Oncorhynchus nerka) caused by a filterable agent have occurred. In 1954, one source of this infectious, filterable agent was found to be adult sockeye viscera used in the diet for the fingerlings. The results of observations on an epizootic in 1958 indicate...
Geological investigations in the U12b.03 and U12b.04 tunnels, Nevada Test Site
W.H. Diment, V. R. Wilmarth, F. A. McKeown, D.D. Dickey, E. N. Hinrichs, T. Botinelly, C. H. Roach, F. M. Byers, C. C. Hawley, G. A. Izett, Alfred Clebsch
1959, Trace Elements Memorandum 996
The papers comprising the various parts of this report contain preliminary results of the U. S. Geological Survey investigations in the U12b.03 and U12b.04 tunnels at the Nevada Test Site, Nye County, Nevada (fig. 1). The geologic studies were undertaken to define the structural, chemical, mineralogic, and some of the...
Gravity and seismic exploration in Yucca Valley, Nevada test site, January-April, 1959
William H. Diment, D.L. Healey, J.C. Roller
1959, Trace Elements Investigations 545
The thickness of the alluvial and tuffaceous deposits that overlie bedrock in Yucca Valley has been inferred from gravity and seismic measurements. Preliminary interpretations indicate that these deposits are thickest in a narrow north-trending trough in the eastern part of the valley. The gravity data delineate a buried north-trending ridge...
Comparison of thickness, grade, and depth of radioactive layers as determined by gamma-ray logging and by core sampling
Carl M. Bunker
1959, Trace Elements Investigations 612
Thickness, grade, and depth data were obtained by analyzing gamma-ray logs and core samples from 56 diamond drill holes penetrating uranium deposits in the Colorado Plateau. The data from the two methods were compared to determine variations found in gamma-ray log interpretation and chemical and radiometric analyses of the drill core. Correlations within each parameter...
