Technique for the application of a streamer-type fish tag
Leonard S. Joeris
1953, Transactions of the American Fisheries Society (82) 42-47
Principal features of the technique are: attachment of the plastic tag by means of a nylon-thread loop prepared in advance of field work; use of a curved surgical needle with cutting edge and a split eye for application of the tag. The procedures for splitting the needle's eye and for...
Abbreviations used in publications of the United States Geological Survey
Water Resources Division, U.S. Geological Survey
1953, Report
The use of abbreviations in publications of the Geological Survey is determined by several forces working in different directions. Pulling in the direction of greater condensation and the freer use of abbreviations and symbols is the desire to achieve greater economy in publications. Working in the opposite direction is the...
A more comprehensive description of Bacterium salmonicida
P. J. Griffin, S. F. Snieszko, S. B. Friddle
1953, Transactions of the American Fisheries Society (82) 129-138
The purpose of this study was to establish a set of descriptive data which could be used as a reference or a standard in the identification of Bacterium salmonicida, the cause of furunculosis in fish. Since a complete description of B. salmonicida was not available, bacteriologists were not in...
The movement of tagged lake trout in Lake Superior, 1950-52
Paul H. Eschmeyer, Russell Daly, Leo F. Erkkila
1953, Transactions of the American Fisheries Society (82) 68-77
A total of 733 native lake trout was tagged at two widely separated localities in Lake Superior; subsequent recaptures numbered 155 fish (21.1 percent) during the year following marking. In October 1950, 116 large lake trout (average total length, 27.3 inches) were tagged near Keweenaw Point, Michigan. Fifteen (12.9 percent)...
Fluctuations in the fisheries of State of Michigan waters of Green Bay
Ralph Hile, George F. Lunger, Howard J. Buettner
1953, Fishery Bulletin of the U.S. Fish and Wildlife Service (54) 1-34
Green Bay, traditionally a major center of production, has assumed in recent years a position of overwhelming dominance in the commercial fisheries of the State of Michigan waters of Lake Michigan. Within the 4-year period 1945-1948 the commercial take in State of Michigan waters of Green Bay increased from 3,317,000...
Relation of suspended-sediment concentration to channel scour and fill
Luna Bergere Leopold, Thomas Maddock Jr.
1953, Conference Paper, Proceedings of the fifth Hydraulics Conference, June 9-11, 1952, arranged by the Iowa Institute of Hydraulic Research
It is known that during the passage of a flood the channel of an alluvial stream scours and fills with considerable rapidity. Though such changes may be random, it seems more likely that there is a definite pattern of channel change directly related both to discharge and to the sediment...
Downstream change of velocity in rivers
Luna Bergere Leopold
1953, American Journal of Science (251) 606-624
Because river slope generally decreases in a downstream direction, it is generally supposed that velocity of flow also decreases downstream. Analysis of some of the large number of velocity measurements made at stream-gaging stations demonstrates that mean velocity generally tends to increase downstream. Although there are many reaches in nearly...
Biologists in the field of wildlife conservation
Daniel L. Leedy
1953, AIBS Bulletin (3) 21-23
We often hear comments such as "people are funny" and "one meets the strangest people!" Such sage remarks are not infrequently directed towards biologists, particularly those engaged in one of the many phases of wildlife conservation work. Bulletins of the "love life" of the raccoon or frog, and biologists who,...
Gamebird weights
A.L. Nelson, A. C. Martin
1953, Journal of Wildlife Management (17) 36-42
No abstract available. ...
Lake Bonneville: Geology of northern Utah Valley, Utah
C. B. Hunt, H.D. Varnes, H. E. Thomas
1953, Professional Paper 257-A
Lake Bonneville was a vast Pleistocene lake that covered 20,000 square miles in northwestern Utah and had a maximum depth of about 1,000 feet. It was a body of water comparable in size to modern Lake Michigan.Surveys of the unconsolidated deposits in the Lake Bonneville basin utilize the same methods...
