The true pikes
John Van Oosten
1960, Fishery Leaflet 496
No abstract available....
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...
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....
Releasing effects in flame photometry. Determination of calcium
J. I. Dinnin
1960, Analytical Chemistry (32) 1475-1480
Strontium, lanthanum, neodymium, samarium, and yttrium completely release the flame emission of calcium from the depressive effects of sulfate, phosphate, and aluminate. Magnesium, beryllium, barium, and scandium release most of the calcium emission. These cations, when present in high concentration, preferentially form compounds with the depressing anions when the solution...
Magnetic susceptibility of tetragonal titanium dioxide
F. E. Senftle, T. Pankey, F. A. Grant
1960, Physical Review (120) 820-825
Careful measurements have been made of the magnetic susceptibility of the rutile and anatase crystalline forms of titanium dioxide. The magnetic susceptibility of a single crystal of high-purity rutile was found to be (0.067±0.0015)×<span id="MJXc-Node-6"...
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...
Vibrio infections among marine and fresh-water fish
Robert R. Rucker
1959, Progressive Fish-Culturist (21) 22-25
In 1951. B. J. Earpio found a vibrio infection among salmon fingerlings being reared in saltwater at the Deception Pass Biological Station of the Washington State Department of Fisheries. The disease waa characterized by erythema at the base of fins and on the sides of the fish, necrotic areas in...
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...
