Age, growth, spawning season, and fecundity of the trout-perch (Percopsis omiscomaycus) in southeastern Lake Michigan
Robert House, LaRue Wells
1973, Journal of the Fisheries Research Board of Canada (30) 1221-1225
Growth of trout-perch (Percopsis omiscomaycus) in the first 2 years of life was somewhat slower in southeastern Lake Michigan (average length at end of second year, 83 mm) than in Lower Red Lake, Minnesota (90 mm), but considerably faster than in Lake Superior (58 mm); size differences in later years...

Toxicity of TFM (lampricide) to six early stages of rainbow trout (Salmo gairdneri)
L.E. Olson, L. L. Marking
1973, Journal of the Fisheries Research Board of Canada (30) 1047-1052
The lampricide TFM (3-trifluoromethyl-4-nitrophenol) was tested against the following life stages of rainbow trout (Salmo gairdneri): green eggs, eyed eggs, sac fry, swim-up fry, fry, and fingerlings in four water hardnesses (12, 44, 170, and 320 mg/liter as CaCO3). The eyed-egg stage was one of the most resistant stages tested, and...

Petrography and stratigraphy of glacial drift, Mesabi-Vermilion Iron Range area, northeastern Minnesota
Thomas C. Winter, R. D. Cotter, H. L. Young
1973, Bulletin 1331-C
Glacial deposits in the Mesabi-Vermilion Iron Range area consist of four major till units and associated glaciofluvial sediments. Particle-size data and pebble, heavy-mineral, clay-mineral, and percentage-soluble content were used in addition to field description of color and texture to describe and correlate the drift units. The lowermost till unit, basal till,...
Waterfowl production on stock-watering ponds in the northern plains
J. T. Lokemoen
1973, Journal of Range Management (26) 179-184
In a 5-year study of stock-watering ponds in western North Dakota, pond size was found to be the major factor influencing duck use. As pond size increased, total pair and brood use per pond increased. Pairs used ponds as small as 0.1 acre in size, but broods were seldom seen...

Radial particle-size segregation during packing of particulates into cylindrical containers
C.D. Ripple, R.V. James, J. Rubin
1973, Powder Technology (8) 165-175
In a series of experiments, soil materials were placed in long cylindrical containers, using various packing procedures. Soil columns produced by deposition and simultaneous vibratory compaction were dense and axially uniform, but showed significant radial segregation of particle sizes. Similar results were obtained with deposition and simultaneous impact-type compaction when...
Paleomagnetism of some Precambrian basaltic flows and red beds, Eastern Grand Canyon, Arizona
D. P. Elston, Scott G. Robert
1973, Earth and Planetary Science Letters (18) 253-265
Lava flows and red sandstone beds near the middle of the Upper Precambrian Grand Canyon Series exhibit stable remanent magnetization. The beds are about 1000 m stratigraphically above rocks of the Grand Canyon Series for which paleomagnetic poles have been reported. All...
Endrin uptake and release by fingerling channel catfish (Ictalurus punctatus)
R.L. Argyle, G.C. Williams, H.K. Dupree
1973, Journal of the Fisheries Research Board of Canada (30) 1743-1744
Fingerling channel catfish (Ictalurus punctatus) offered diets containing 0.04–4.0 μg endrin/g food (dry weight) rapidly accumulated the pesticide. Amounts in the tissues were directly proportional to amounts in the food. Dietary endrin had no measurable effect on growth or mortality. After endrin was withdrawn from the diet, it rapidly disappeared and...
Imaging characteristics of photogrammetric camera systems

In view of the current interest in high-altitude and space photographic systems for photogrammetric mapping, the United States Geological Survey (U.S.G.S.) undertook a comprehensive research project designed to explore the practical aspects of applying the latest image quality evaluation techniques to the analysis of such systems. The project had two...
Fish viruses: Buffers and methods for plaquing eight agents under normal atmosphere
K. Wolf, M. C. Quimby
1973, Applied Microbiology (25) 659-664
A universal procedure was sought for plaque assay of eight fish viruses (bluegill myxovirus, channel catfish virus, eel virus, Egtved virus, infectious hematopoietic necrosis virus, infectious pancreatic necrosis virus, lymphocystis virus, and the agent of spring viremia of carp (Rhabdovirus carpio), in dish cultures of various fish cells. Eagle minimal...
Effect of sea water interaction on strontium isotope composition of deep-sea basalts
Dasch E. Julius, C. E. Hedge, J. Dymond
1973, Earth and Planetary Science Letters (19) 177-183
Analyses of rim-to-interior samples of fresh tholeiitic pillow basalts, deuterically altered holocrystalline basalts, and older, weathered tholeiitic basalts from the deep sea indicate that 87Sr/86Sr ratios of the older basalts are raised by low temperature interaction with strontium dissolved in sea water. 87Sr/86Sr correlates...
