Toxicity of 33 NCS to freshwater fish and sea lamprey
Leif L. Marking, Everett L. King, Charles R. Walker, John H. Howell
1970, Investigations in Fish Control 38
The chemical 33NCS (3'-chloro-3-nitrosalicylanilide) was evaluated as a fish control agent and as a larvicide for sea lampreys at the Fish Control Laboratories of the Bureau of Sport Fisheries and Wildlife and the Hammond Bay Biological Station of the Bureau of Commercial Fisheries. The chemical is rapidly toxic to many...
Accumulation of radionuclides in bed sediments of the Columbia River between Hanford reactors and McNary Dam
Jack L. Nelson, W.L. Haushild
1970, Water Resources Research (6) 130-137
Amounts of radionuclides from the Hanford reactors contained in bed sediments of the Columbia River were estimated by two methods: (1) from data on radionuclide concentration for the bed sediments between the reactors and McNary Dam, and (2) from data on radionuclide discharge for river stations at Pasco, Washington, and...
Summer foods of lesser scaup in subarctic taiga
James C. Bartonek, H. W. Murdy
1970, Arctic (23) 35-44
Reports on the food of 25 adult and 38 juvenile Aythya affinis, collected in June-Sept 1967 along the Yellowknife Highway north of Great Slave Lake. The vegetation, physiography and ponds of the area, the collecting and statistical methods are briefly described. Approx 99% of the scaup diet was animal material; juveniles...
A hermaphroditic coregonine from Lake Michigan
Thomas A. Edsall
1970, Transactions of the American Fisheries Society (99) 611 p.
Hermaphroditism is relatively rare among the Salmonidae (See Atz, 1964 for a comprehensive review) and has never been reported for coregonine fishes. Recent examination of a collection of coregonines at the Great Lakes Fishery Laboratory disclosed a hermaphroditic bloater(Coregonus hoyi). The fish was captured in a gill net...
Lunar Maria and circular basins-a review
D.E. Stuart-Alexander, K. A. Howard
1970, Icarus (12) 440-456
Lunar Orbiter data make it possible to examine the distribution and relations of maria and large circular basins over the entire Moon. The restricted distribution and age of the maria are in marked contrast to the apparently random distribution in time and place of the circular basins, some of which...
Lithium metaborate flux in silicate analysis
C.O. Ingamells
1970, Analytica Chimica Acta (52) 323-334
Lithium metaborate is an effective flux for silicates and other rock-forming minerals. The glass resulting from fusion is mechanically strong, reasonably nonhygroscopic, and is readily soluble in dilute acids. These characteristics lead to its use in X-ray spectrography and in methods which require whole-rock solutions,...
Geology: Craters

Stress of anesthesia with M.S. 222 and Benzocaine in Rainbow Trout (Salmo gairdneri)
Gary Wedemeyer
1970, Journal of the Fisheries Research Board of Canada (27) 909-914
Rainbow trout (Salmo gairdneri) anesthetized with M.S. 222 for periods up to 12 min experience interrenal ascorbate depletion, uremia, and moderate hypercholesterolemia. Anesthesia with neutralized M.S. 222 (pH 7) or benzocaine prevented these changes and significantly reduced the variability in plasma glucose, cholesterol, and cortisol, indicating that the stress of anesthesia...
Temperature tolerance of bloater (Coregonus hoyi)
Thomas A. Edsall, Donald V. Rottiers, Edward H. Brown
1970, Journal of the Fisheries Research Board of Canada (27) 2047-2052
Juvenile and young adult bloaters (Coregonus hoyi) were tested for tolerance to high temperatures. The ultimate upper lethal temperature of juvenile bloaters (26.75 C) appeared to be slightly higher than that of young adult bloaters, but was similar to that of juvenile ciscoes,Coregonus artedii (26.0 C), the only other North American coregonine for...
Effects of gossypol on rainbow trout Salmo gairdneri Richardson
Roger L. Herman
1970, Journal of Fish Biology (2) 293-303
Rainbow trout were fed gossypol acetate or cottonseed meals containing gossypol for 14 months. Toxic effects were indicated by growth depression, reduced hematocrit, hemo-globin, and total plasma protein. Histological changes were noted, particularly in the liver and kidney....
Extreme female predominance in the bloater (Coregonus hoyi) of Lake Michigan in the 1960's
Edward H. Brown Jr.
C.C. Lindsey, C.S. Woods, editor(s)
1970, Book chapter, Biology of coregonid fishes
The sex composition and other biological characteristics of the bloater changed substantially during recent decades of continuous ecological change in Lake Michigan. The percentages of females increased from 72% of the bloaters samples in 1928-32 to 95% in 1963, and ranged from 94 to 97% in 1964-69. The unusual predominance...
Television experiment for Mariner Mars 1971
H. Masursky, R. Batson, W. Borgeson, M. Carr, J. McCauley, D. Milton, R. Wildey, D. Wilhelms, B. Murray, N. Horowitz, R. Leighton, R. Sharp, W. Thompson, G. Briggs, P. Chandeysson, E. Shipley, C. Sagan, J. Pollack, J. Lederberg, E. Levinthal, W. Hartmann, T. McCord, B. Smith, M. Davies, G. De Vaucouleurs, C. Leovy
1970, Icarus (12) 10-45
The Television Experiment objectives are to provide imaging data which will complement previously gathered data and extend our knowledge of Mars. The two types of investigations will be fixed-feature (for mapping) and variable-feature (for surface and atmospheric changes). Two cameras with a factor-of-ten difference in resolution will be used on...
