U.S. Federal fishery research on the Great Lakes through 1956
Ralph Hile
1957, Special Scientific Report - Fisheries 226
The major purpose of this publication is to present an annotated bibliography of papers resulting from Federal investigations on the Great Lakes fish and fisheries since the formal initiation of a continuing research program by the Fish and Wildlife Service. It is believed that this purpose can be served best...
Ringworm in a population of snowshoe hares
Lowell W. Adams, S. B. Salvin, W. J. Hadlow
1956, Journal of Mammalogy (37) 94-99
The occurrence of ringworm, or dermatomycosis, in wild animals has been rarely reported. DeLamater (1939) described infections of Trichophyton mentagrophytes in common gray squirrels on and near the Johns Hopkins University campus at Baltimore. Errington (1942) and Charles (1946) reported on the occurrence of T. mentagrophytes in 35 of 364 litters (9.6%) of muskrats...
Lignasan for bacterial gill disease
Robert R. Rucker, B. J. Earp, Roger E. Burrows
1956, Progressive Fish-Culturist (18) 75-77
Bacterial gill disease plagues salmon and trout in many hatcheries: some infections are sporadic, but others are continual. An inexpensive, easily applied, stable, safe chemical would be highly advantageous for treatment. The use of Roccal as a 1-hour treatment for bacterial gill disease (Fish 1947) was developed at the...
Long-term trends of ground-water levels in the United States
V.C. Fishel
1956, Eos, Transactions, American Geophysical Union (37) 429-435
Ground-water levels at the end of 1954 were at or near record-low stages throughout most of the southern two-thirds of the United States. These low stages, like those of the early 1930's, have led to frequent expression of the opinion that the water table throughout the country is continuously falling...
Tissue damage in salmonids caused by Halisidota argentata Packard
E. M. Wood, W. T. Yasutake
1956, Journal of Parasitology (42) 544-546
During the histological examination of a collection of wild and hatchery salmonids, a peculiar foreign body was occasionally observed in various organs, particularly in the viscera. These objects, usually accompanied by a focal inflammation, were observed in 10 of 75 samples of wild trout and salmon collected in Oregon and...
Ground water in Wisconsin
William James Drescher
1956, Wisconsin Geological & Natural History Survey Information Circular 3
The purpose of this report is to describe in general the occurrence, source, movement, and use of ground water in Wisconsin in order that present problems of ground-water development may be understood and to point out the need for study and evaluation of the potential ground water available. Areas with...
Preliminary chemical quality study in the Manhattan Beach area, California
Robert Brennan
1956, Bulletin 63-E
In 1904 Mendenhall (1905) made a survey of the ground water conditions in southern California. At the time of his survey the piezometric surface in the area was above sea level, but since that time water levels have declined. During the 1920's, years of rapid development, the water levels declined...
Interim report on surface water resources and quality of waters in Lee County, Florida
William E. Kenner, Eugene Brown
1956, Information Circular 7
The purpose of this report is to provide such information on the surface-water resources of the county as inay be useful in planning for their more intensive use. This report is not intended to provide final answers to all questions concerning the occurrence of surface water in the c:ounty; because...
Heavy-mineral suites in unconsolidated Paleocene and younger sands, western Tennessee
Reginald R. Blankenship
1956, Journal of Sedimentary Petrology (26) 356-362
Heavy-mineral suites from unconsolidated sands of Wilcox and Claiborne age (Eocene) in the subsurface of western Tennessee were tabulated and compared with heavy-mineral suites obtained from outcropping sands known to be of Midway (Paleocene) and Wilcox age and younger. In the subsurface at Memphis, both pink and colorless garnet are...
