Toxicity of 4,346 chemicals to larval lampreys and fishes
Vernon C. Applegate, John H. Howell, A.E. Hall, Manning A. Smith
1957, Special Scientific Report - Fisheries 207
The problem of controlling the sea lamprey in the upper Great Lakes has received considerable attention in recent years and requires no review here (Applegate and Moffett. 1955). Electromechanical weirs and traps and electrical barriers have been developed which can be successfully employed to block and/or destroy spawning runs of...

Thoron-meso-tartaric acid system for determination of thorium
Mary H. Fletcher, F. S. Grimaldi, Lillie B. Jenkins
1957, Analytical Chemistry (29) 963-967
In the spectrophotometric determination of thorium with thoron, meso-tartaric acid is used as a masking reagent for zirconium. The effects of different experimental variables such as the concentrations of the reagents, time, and temperature, and the behavior of 35 ions which might be present in thorium ores are discussed. A...

The control of the upstream movement of fish with pulsated direct current
Alberton L. McLain
1957, Transactions of the American Fisheries Society (86) 269-284
Alternating-current electromechanical devices installed in the mouths of streams have proved effective in stopping the spawning migrations of the parasitic sea lamprey (Petromyzon marinus) which has seriously damaged Great Lakes fisheries. In a few streams, excessive mortality has occurred to other fish at the alternating-current barriers. A direct-current unit was...
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

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...
