Evolution and distribution of the coregonids
Stanford H. Smith
1957, Journal of the Fisheries Research Board of Canada (14) 599-604
Increased knowledge of the morphological and physiological plasticity of the coregonids has minimized the significance of conflicting morphological data that have retarded the development of an evolutionary theory. Of the four phyletic lines recognized through worldwide studies,Coregonus originated in the lake and stream area of northwest Eurasia, Stenodus andProsopium evolved in the rivers of...
Structure and growth of scales of yellow perch of Green Bay
Leonard S. Joeris
1957, Transactions of the American Fisheries Society (86) 169-194
The appearance of the scales of yellow perch differs with the location on the fish's body. Comparison of scales of Green Bay perch taken above and below the lateral line reveals the former to have more sharply defined circuli and to exhibit fewer false annuli and less of the shading...
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...
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...

The flame photometric determination of calcium in phosphate, carbonate, and silicate rocks
Henry Kramer
1957, Analytica Chimica Acta (17) 521-525
A flame photometric method of determining calcium in phosphate, carbonate, and silicate locks has been developed Aluminum and phosphate interference was overcome by the addition of a large excess of magnesium. The method is rapid and suitable for routine analysis Results obtained are within ± 2% of the calcium oxide...

Core logs from Owens, China, Searles, and Panamint basins, California
George I. Smith, Walden P. Pratt
1957, Bulletin 1045-A
Detailed logs of drill cores are presented in this report. The drill cores are of sediments from four basins that were occupied during the Pleistocene by a continuous chain of lakes. Owens Lake basin (one hole, 920 feet) contains fine-grained sediments and includes locally many diatoms and ostracodes. China Lake...

History of Red Lakes fishery, 1917-38, with observations on population status
John Van Oosten, Hilary J. Deason
1957, Special Scientific Report - Fisheries 229
A historical account traces the development of the commercial fisheries of the Red Lakes, Minnesota, from its inception in 1917 as a war measure through 1938. The trends of production and catch per unit of effort were followed for the principal species with notes on statistics of the minor...

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...

Histopathologic changes of a virus-like disease of sockeye salmon
E. M. Wood, W. T. Yasutake
1956, Transactions of the American Microscopical Society (75) 85-90
Rucker et al., (1953) described a disease of sockeye salmon (Oncorhynchus nerka) of possible viral etiology. First seen in Washington in 1951 with relatively minor losses, the disease recurred in 1952 killing over two million fingerling salmon with a mortality rate of 91.5 percent (Watson, 1954). In...
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...

Histopathology of fish. II. The salmon-poisoning fluk
1956, Progressive Fish-Culturist (18) 22-25
THE SALMON-POISONING FLUKE is misnamed as far as the fish culturist is concerned, for the disease affects dogs, not fish. There is considerable evidence, however, that fish may also suffer from the complex chain of events leading from snail to dying dog. Histological studies indicate that young salmon and trout...
