Diatoms as food of larval sea lampreys in a small tributary of northern Lake Michigan
Patrick J. Manion
1967, Transactions of the American Fisheries Society (96) 224-226
The food and food preferences of sea lamprey ammocoetes have not been investigated. The food of the larval American brook lamprey, Lampetra lamottei, in the Great Lakes region consisted mainly of diatoms and desmids according to Creaser and Hann. Schroll discussed the biology of feeding of ammocoetes of Lampetra planeri...

Harry D. Van Meter, William F. Shepherd
1967, Conservationist (22) 2-3
The objectives of these cruises of the research vessel Musky II in 1965 and 1966 were: To determine changes in the fish population and environmental conditions in recent years; to determine if the geographic and depth distributions of certain species of fish in the summer differed from that in the...
An all-season trap for downstream-migrating fish and other aquatic organisms
Alberton McLain, Patrick J. Manion
1967, Progressive Fish-Culturist (29) 114-117
AN INVESTIGATION OF THE LARVAL STAGES OF THE SEA LAMPREY (Petromyzon marinus), which started in 1960, required a trap that could capture lamprey larvae moving downstream, and that would operate efficiently throughout the year. Sub zero temperatures in the winter and flooding during the spring were the most critical operational...
Contributions of year-classes of blue pike to the commercial fishery of Lake Erie, 1943-59
John W. Parsons
1967, Journal of the Fisheries Research Board of Canada (24) 1035-1066
The blue pike (Stizostedion vitreum glaucum) contributed about 12.7 million lb annually to the commercial production of fish in Lake Erie in 1915–59. Production averaged about 27% of the total for all species; in some years it exceeded 50%. The catch fluctuated greatly and was featured by a series of...
Biology of the freshwater drum in western Lake Erie
Thomas A. Edsall
1967, Ohio Journal of Science (67) 321-340
Information on the biology of the freshwater drum or sheepshead (Aplodinotus grunniens) was collected in Lake Erie during a fishery and limnological study made by the Bureau of Commercial Fisheries in 1957 and 1958. Growth of the sheepshead in 1958 was slower than in 1927, and slower than the growth...
Returns of hatchery-reared lake trout in southern Lake Superior, 1955-62
Richard L. Pycha, George R. King
1967, Journal of the Fisheries Research Board of Canada (24) 281-298
Experimental plantings of fin-clipped lake trout (Salvelinus namaycush) of various ages have been made in southern Lake Superior since 1952. The catch of planted lake trout by the commercial fishery was used to measure the success of stocking. Estimates of total returns were based on samples of 8.2 to 21.2%...
Infection of the walleye, Stizostedion v. vitreum, of western Lake Erie with Bothriocephalus cuspidatus (Cooper)
David R. Wolfert, Vernon C. Applegate, Leonard N. Allison
1967, Papers of the Michigan Academy of Science, Arts, and Letters (52) 105-114
In recent years appreciable changes have taken place in the biota and physiochemical conditions in Lake Erie. The accelerated eutrophication of the lake has been accompanied by the near disappearance of several fish species, e.g., blue pike (Stizostedion vitreum glaucum), lake herring (Coregonus artedi), lake trout (Salvelinus namaycush), sauger...
Morphological abnormalities among lampreys
Patrick J. Manion
1967, Copeia (1967) 680-681
The experimental control of the sea lamprey (Petromyzon marinus) in the Great Lakes has required the collection of thousands of lampreys. Representatives of each life stage of the four species of the Lake Superior basin were examined for structural abnormalities. The most common aberration was the presence of...

Precision measurement of lead isotopes ratios: preliminary analyses from the U.S. mine, Bingham Canyon, Utah
J. S. Stacey, W. J. Moore, R.D. Rubright
1967, Earth and Planetary Science Letters (2) 489-499
A gas-source mass spectrometer has been constructed for the precise measurement of lead isotope ratios. Sixteen analyses on 4 different preparations of the same galena made over a period of 2 months gave 95% confidence limits (per analysis) of 206Pb/204Pb= 0.080%, 207Pb/206Pb= 0.042%and208Pb/206Pb=...
Yakima basalt of the Tieton River area, south-central Washington
Donald A. Swanson
1967, Geological Society of America Bulletin (78) 1077-1110
Up to 1700 feet of the upper Miocene-lower Pliocene Yakima Basalt of the Columbia River Group underlie much of the eastern flank of the Cascade Range in the Tieton River area, Yakima County, Washington. Local prebasalt relief was more than 1700 feet, so thicknesses of each of the 15...
Hydrology of the Valley-fill and carbonate-rock reservoirs, Pahrump Valley, Nevada-California
Glenn T. Malmberg
1967, Water Supply Paper 1832
This is the second appraisal of the water supply of Pahrump Valley, made 15 years after the first cooperative study. In the first report the average recharge was estimated to be 23,000 acre-feet per year, only 1,000 acre-feet more than the estimate made in this report. All this recharge was...

The occurrence and origin of lamellar troilite in iron meteorites
R. Brett, E.P. Henderson
1967, Geochimica et Cosmochimica Acta (31) 721-730
A number of iron meteorites contain elongated inclusions consisting predominantly of troilite, which have been termed Reichenbach lamellae. Two types of inclusions exist, the first up to 6 cm long and 0·2 mm wide, the second up to 2 cm long and 3 mm wide. The first type contains troilite...

Description of a bacterium associated with redmouth disease of rainbow trout (Salmo gairdneri)
A. J. Ross, R.R. Rucker, W.H. Ewing
1966, Canadian Journal of Microbiology (12) 763-770
A description was given of a gram-negative, peritrichously flagellated, fermentative bacterium that was isolated on numerous occasions from kidney tissues of rainbow trout (Salmo gairdneri) afflicted with redmouth disease. Although the bacteria apparently were members of the family Enterobacteriaceae, it was impossible to determine their taxonomic position within the family...
