The age, growth, sexual maturity, and sex ratio of the common whitefish, Coregonus clupeaformis (Mitchill), of Lake Huron
John Van Oosten
1939, Papers of the Michigan Academy of Science, Arts, and Letters (24) 195-221
During five years (1939-43) of nutritional research on pen-reared bobwhite quail at the Patuxent Research Refuge, Bowie, Maryland, observations on picking among birds of all ages showed the following results: 1. Picking occurred on all grains tested: corn, wheat, oats, oat groats, barley, millet, buckwheat, kaffir, and mixtures of cereals....
The age, growth, and feeding habits of the whitefish Coregonus clupeaformis (Mitchell), of Lake Champlain
John Van Oosten, Hilary J. Deason
1939, Transactions of the American Fisheries Society (68) 152-162
This study is based on 120 whitefish collected in northern Lake Champlain (Missisquoi Bay) in 1930 and on 175 whitefish taken in southern Lake Champlain in 1931. Since the whitefish population had not been exploited commercially after 1912 in United States waters and after 1915 in Canadian waters, its study...
The evolution of habit in Tempskya
C.B. Read
1939, Lloydia (2) 63-72
1. The genus Tempskya Corda, of Upper Cretaceous age in western America, is characterized by a markedly dichotomous solenostelic stem system sheathed in a felt of its own adventitious roots. A composite stemlike structure is thus formed which has been termed a false stem. 2. As primary bases for the...
Observations on Henneguya salminicola Ward, a myxosporidian parasitic in Pacific salmon
F. F. Fish
1939, Journal of Parasitology (25) 169-172
Henneguya salminicola was described in 1919 by Dr. H. B. Ward from cysts found in the body musculature of a silver salmon (Oncorhynchus kisutch Walbaum) taken from the Stickeen River in southeastern Alaska. Ward described the cysts as “pyriform, fairly uniform in size, and hard to the touch. . ....
Migratory fish, a problem of interstate cooperation?
John Van Oosten, William C. Adams, William L. Finley, Fred A. Westerman
1939, Transactions of the North American Wildlife Conference (4) 25-43
Bobwhite quail chicks, when given a choice of balanced diets in which the essential difference was the protein supplement, showed preferences for one diet containing 49 per cent peanut oil meal, another containing a mixture of 9 per cent meat and bone scraps (50% protein) with 38 per cent soybean...
Save the Great Lakes fisheries!
John Van Oosten
1939, Outdoor American (4) 4-5, 7
During the winters of 1939-40 and 1940-41, two experiments involving 456 bobwhite quail, were conducted at the Patuxent Research Refuge, Bowie, Maryland, to determine the palatability and comparative feeding value of 20 common wild quail-foods when offered as a part of a maintenance diet....2. Mortality was low on all diets,...

A.B. Purton
1938, Utah State Engineer Biennial Report 21-9
Investigations for the surface-water resources of the State have been continued during the biennium under the standard form of co-operative agreement between the U.S. Geological Survey and the State of Utah through their respective agents. The nature, extent, and value of these co-operative investigations are discussed in the State Engineer’s...

A summary of past investigations in Utah and a description of the work done during the 1934-36 biennium are included in the State Engineer’s Twentieth Biennial Report (pp. 91-106). Co-operative investigation with the State Engineer, begun on July 1, 1935, has been continued during the past biennium. To provide for...
Treat - think - and be wary, for tomorrow they may die
F. F. Fish
1938, Progressive Fish-Culturist (5) 1-9
For some very strange reason it is easy to minimize the villian's role, played by disease-producing organisms, in the theater of modern fish culture. Much concern is felt over the food bills footed each month by the hatcheries, but very little is thought about the dead fish which are picked...
