Low production may not mean depletion
Ralph Hile

Five feeding tests were conducted at the Patuxent Research Refuge, Bowie, Maryland, to determine the value or dwarf and smooth sumac fruits as the sole diet of quail, as well as a supplement to other feedstuffs.....When whole sumac fruits were force-fed quail, either alone or in combination with millet seed,...
Net selectivity on the Great Lakes
John Van Oosten
1936, Gold Medal Netting News (10) 2-3
Two experiments, using 784 bobwhite quail chicks, were conducted at the Patuxent Research Refuge, Bowie, Maryland, to find a growing diet that would meet wartime restrictions. In 1941 a diet containing 14 per cent sardine fish meal was formulated and gave satisfactory results from the standpoints of survival and growth....
Summary of investigations on the morphometry of the cisco, Leucichthys artedi (Le Sueur), in the lakes of the northeastern highlands, Wisconsin
Ralph Hile
1936, Papers of the Michigan Academy of Science, Arts, and Letters (21) 619-634
The morphometric studies on the cisco or lake herring, Leucichthys artedi (Le Sueur), which are briefly summarized in this paper are part of a program of investigation of the fishes of the lakes in the northeastern highland district, Wisconsin. For the morphometric studies, 1,548 specimens were employed, all of...
A western type of bacterial gill disease
F. F. Fish
1935, Transactions of the American Fisheries Society (65) 85-87
The first reference to a pathological condition of the gill tissues of salmonid fishes was made by Osburn in 1910. This author in describing a progressive infolding of the opercula of trout, commonly known to hatcherymen as "short gill covers," mentioned a marked proliferation on the gill epithelium as accompanying...
The microscope in the hatchery
F. F. Fish
1935, Progressive Fish-Culturist (2) 1-16
Without the aid of the microscope, it is safe to assume that fish Culture would now stand exactly where it did seventy-five years ago when methods of artificial fertilization were first applied. It is also safe to assume that the results from fish culture would be as unsatisfactory as they...
The bacterial diseases of fish
F. F. Fish
1935, Progressive Fish-Culturist (2) 1-9
Of all the diseases responsible for the losses in the hatchery, those caused by the microscopic one-celled organisms, the bacteria, are the most common and present the most serious problem to the hatcheryman. They are found at practically every trout and salmon hatchery during some period of the year. The...
The protozoan diseases of hatchery fish
F. F. Fish
1935, Progressive Fish-Culturist (2) 1-4
Following the somewhat bleak picture painted in the consideration of the bacterial diseases of hatchery fish in the last number of The Progressive Fish Culturist, it is a relief to turn to another large group of fish diseases caused by small, single-celled parasitic animals known as the protozoa. To the...
The Bureau of Fisheries disease service
F. F. Fish
1935, Progressive Fish-Culturist (2) 9-12
Picture yourself bending over a trough picking eggs. The clatter of hoofs suddenly rings from the snow-covered hatchery roof—or if you must be technical—from the driveway. The hatchery door opens and in walks a bewhiskered gentleman wearing a brilliant red suit—it's Santa Claus. He walks slowly over to where you...

John T. Lonsdale
1935, Water Supply Paper 676
Atascosa and Frio Counties are in southwestern Texas and form a part of the Winter Garden district. The purpose of the investigation here recorded was to determine the source, quantity, and quality of the ground water used for irrigation and other purposes in the area....
Water utilization in the Snake River Basin
William Glenn Hoyt, Herman Stabler
1935, Water Supply Paper 657
The purpose of this report is to describe the present utilization of the water in the Snake River Basin with special reference to irrigation and power and to present essential facts concerning possible future utilization. No detailed plan of development is suggested. An attempt has been made, however, to discuss...
