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...
River channel change with time : An example
Luna Bergere Leopold
1973, Geological Society of America Bulletin (84) 1845-1860
Monumented channel cross sections were resurveyed over a period of 20 yrs (1953 to 1972) to determine the amount and kind of change of channel area and position on a 3.7-sq-mi basin, Watts Branch near Rockville, Maryland. For the first 12 yrs, the channel progressively but slowly became smaller as...
Nutritional factors in the biochemical pathology of Corynebacterial kidney disease in the coho salmon (Oncorhynchus kisutch)
Gary A. Wedemeyer, A. J. Ross
1973, Journal of the Fisheries Research Board of Canada (30) 296-298
The influence of diet ingredient on the morbidity and biochemical pathogenesis of corynebacterial kidney disease was investigated using juvenile coho salmon (Oncorhynchus kisutch) fed the Abernathy dry ration made up with either corn gluten or cottonseed meal (isoprotein, isocaloric substitution). Evaluation of incidence of infection, pituitary activation and aspects of...
Some physiological aspects of sublethal heat stress in the juvenile steelhead trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch)
Gary Wedemeyer
1973, Journal of the Fisheries Research Board of Canada (30) 831-834
A rapid (3 min) but sublethal temperature increase from 10 to 20 imposed a greater stress on juvenile coho salmon (Oncorhynchus kisutch) than on juvenile steelhead trout (Salmo gairdneri). Both species suffered hyperglycemia, hypocholesterolemia, increased blood hemoglobin, and decreased blood sugar regulatory precision, but the steelhead recovered more quickly. Acid–base equilibrium...
Hatchability tests with eggs from captive wood ducks
Harold A. Doty
1972, Poultry Science (51) 849-853
The effect of diet and artificial incubation on fertility and hatchability of wood duck (Aix sponsa) eggs and survival of young was measured. Hatchability of eggs from hens fed a diet containing 37 percent protein was increased significantly (P<0.05) over that of hens fed a diet containing 17 percent protein. Hatchability was...
Hydrologic reconnaissance of the Promontory Mountains area Box Elder County, Utah
James W. Hood
1972, Technical Publication 38
This report is the eleventh in a series by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, which describes the water resources of the western basins of Utah (fig. 1). Its purpose is to present hydrologic data for the Promontory Mountains...
Developing a state water plan: Ground-water conditions in Utah, spring of 1972
C.T. Sumison, L.J. Bjorklund, L. J. McGreevy, E.L. Bolke, R. W. Mower, L. R. Herbert, L. L. Miller, R.G. Butler, D. B. Adams, G. W. Sandberg
1972, Cooperative Investigations Report 10
This report is the ninth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series are prepared cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources and are designed to provide data to enable interested parties such as legislators, administrators,...
Bibliography of U.S. Geological Survey water-resources reports for Utah
1972, Utah Division of Water Rights Information Bulletin 22
This bibliography contains a complete listing to December 31, 1971, of reports relating to the water resources of Utah prepared by personnel of the U.S. Geological Survey. Discussions of the related subjects of geology, hydrology, and chemical quality of the water are included in many of the reports. The reports...
