Chemical and histological studies of wild and hatchery salmon in fresh water
E. M. Wood, W. T. Yasutake, J.E. Halver, A.N. Woodall
1960, Transactions of the American Fisheries Society (89) 301-307
In a study of coho salmon (Oncorhynchus kisutch), the gross chemical and histological changes occurring over a 14-month period spent in fresh water were determined. The determinations were made at 3-month intervals on: 1) hatchery-reared fish, 2) fish hatchery-reared for 3, 6, 9, and 12 months and then planted in...
Ovarian fluid: Its role in fertilization
R.R. Rucker, J.F. Conrad, C.W. Dick
1960, Progressive Fish-Culturist (22) 77-78
FISH-CULTURISTs, in general, do not agree as to the time of actual fertilization of artificially spawned salmonid eggs. Some fish-culturists believe that the eggs are fertilized in the milt before water is added, while others are equally certain that fertilization is not achieved until after water is added. This difference...
A Virus-like disease of chinook salmon
A. J. Ross, J. Pelnar, R.R. Rucker
1960, Transactions of the American Fisheries Society (89) 160-163
Consideration is given to a recurring disease of early feeding chinook salmon fingerlings at the Coleman, California, Federal Fish Cultural Station. The infection becomes manifest in the early spring months at low water temperatures and abates as the water temperature rises. Bacteriological studies have failed to yield the presence...
National water resources and problems
Roy E. Oltman, Kenneth A. MacKichan, Glennon N. Mesnier, Frank H. Rainwater, Horace G. Thomasson
1960, Report
Water problems exist in all parts of the United States. Furthermore, the problems are becoming more acute and widespread as population and industry grow. The need is pressing for wider appreciation of the nature of water problems. This requires a background of basic facts about the occurrence of water, its...
Racoon predation on waterfowl
L. M. Llewellyn, Clark G. Webster
1960, Transactions of the North American Wildlife and Natural Resources Conference (25) 180-185
Bureau of Sport Fisheries and Wildlife Pesticide-Wildlife Review: 1959
J.B. DeWitt, J.L. George
1960, Circular No. 84 revised
Research findings of the Bureau of Sport Fisheries and Wildlife, State agencies and independent research workers in Ala., Ark., Fla., Ga., La., Mass., Mich., Mont., N. Dak., Tex., and Wis. are summarized in this report together with recommendations for reducing damage from pest control operations. Major topics discussed are:...
Experimental drill hole logging in potash deposits of the Carlsbad district, New Mexico
C.L. Jones, C. Gilbert Bowles, Kenneth Granville Bell
1960, Open-File Report 60-84
Experimental logging of holes drilled through potash deposits in the Carlsbad district, southeastern New Mexico, demonstrate the considerable utility of gamma-ray, neutron, and electrical resistivity logging in the search for and identification of mineable deposits of sylvite and langbeinite. Such deposits are strongly radioactive with both gamma-ray and neutron well...
Origin and chemical composition of evaporite deposits
George William Moore
1960, Open-File Report 60-99
A comparative study of marine evaporite deposits forming at the present time along the pacific coast of central Mexico and evaporite formations of Permian age in West Texas Basin was made in order to determine if the modern sediments provide a basis for understanding environmental conditions that existed during deposition...
