A review of advances in the study of diseases of fish: 1954-1964
G. Post
1965, Progressive Fish-Culturist (27) 3-12
STUDY OF DISEASE IN ANIMALS, INCLUDING MAN, has progressed rapidly in the past decade. Looking back, we find amazing success in the study of man's diseases and possibly only a little less success in studies of diseases of domesticated homeothermic animals. We who are interested in the poikilothermic animals may feel...
Characteristics and identification of oxidative Pseudomonads isolated from diseased fish
G. L. Bullock, S. F. Snieszko, C. E. Dunbar
1965, Journal of General Microbiology (38) 1-7
Several characteristics of 20 strains of oxidative pseudomonads, all but one of which were isolated from freshwater fish, were determined. All strains oxidized glucose and gluconate, produced NH3 from 1 % peptone, grew at 6, 12, 20 and 30° and produced cytochrome oxidase. Lipase was produced by 17 of the...
Alkali content of alpine ultramafic rocks
W. Hamilton, W. Mountjoy
1965, Geochimica et Cosmochimica Acta (29) 661-671
The lower limit of abundance of sodium and potassium in ultramafic rocks is less than the threshold amount detectable by conventional analytical methods. By a dilutionaddition modification of the flame-spectrophotometric method, sodium and potassium have been determined in 40 specimens of alpine ultramafic...
Eocene and miocene rocks off the northeastern coast of the United States
T. G. Gibson
1965, Deep-Sea Research and Oceanographic Abstracts (12)
A grab sample from a depth of 1675 m at a point south of Cape Cod contains early Eocene planktonic Foraminifera and is correlated with the Globorotalia rex zone of Trinidad. The assemblage indicates a depth comparable to that existing today. Regional relations suggest that the Cretaceous and Eocene deposits deepen...
Servo-amplifiers for ion current measurement in mass spectrometry
J. S. Stacey, R.D. Russell, F. Kollar
1965, Journal of Scientific Instruments (42) 390-394
A servo-voltmeter can provide a useful alternative to the d.c. amplifier or vibrating reed electrometer for the accurate measurement of mass spectrometer ion currents, and has some advantages which recommend its use in certain applications. A generalized analysis based on servomechanism theory is presented as an aid for understanding the...
Vacuum-jacketed hydrofluoric acid solution calorimeter
R. A. Robie
1965, Review of Scientific Instruments (36) 484-486
A vacuum‐jacketed metal calorimeter for determining heats of solution in aqueous HF was constructed. The reaction vessel was made of copper and was heavily gold plated. The calorimeter has a cooling constant of 0.6 cal‐deg−1‐min−1, approximately ¼ that of the air‐jacketed calorimeters most commonly used with HF. It reaches equilibrium within 10 min after turning off the heater current. Measurements...
Natural recharge and localization of fresh ground water in Kuwait
R.E. Bergstrom, R.E. Aten
1965, Journal of Hydrology (2) 213-231
Fresh ground water (200 parts per million total dissolved solids and upwards) occurs in portions of Pleistocene sandstone aquifers beneath basins and wadis in north Kuwait where the mean rainfall is about five inches per year. The fresh water is surrounded and underlain by brackish water (> 4000 ppm TDS)....
Glass electrode determination of sodium in closed basin waters
A.H. Truesdell, B.F. Jones, A. S. Van Denburgh
1965, Geochimica et Cosmochimica Acta (29) 725-736
Because of its direct relation to total dissolved solids content, sodium concentration is the most useful single hydrochemical parameter of closed basin waters in the western United States. Therefore, it is advantageous to have a rapid method for sodium determination which could be...
The binary system K2SO4CaSO4
J.J. Rowe, G.W. Morey, I.D. Hansen
1965, Journal of Inorganic and Nuclear Chemistry (27) 53-58
The binary system K2SO4CaSO4 was studied by means of heating-cooling curves, differential thermal analysis, high-temperature quenching technique and by means of a heating stage mounted on an X-ray diffractometer. Compositions and quench products were identified optically and by X-ray. Limited solid solution of CaSO4 in...
A new Rosalina (foraminifera) parasitic on a bivalve
R. Todd
1965, Deep-Sea Research and Oceanographic Abstracts (12)
In a collection of pelecypods from deep water off the west coast of Africa, several specimens of a new species of the foraminifer, Rosalina, are attached to the umbonal area of the bivalve. In addition, numerous attachment scars are observed on the exterior...
Solution of rocks and refractory minerals by acids at high temperatures and pressures. Determination of silica after decomposition with hydrofluoric acid
I. May, J.J. Rowe
1965, Analytica Chimica Acta (33) 648-654
A modified Morey bomb was designed which contains a removable nichromecased 3.5-ml platinium crucible. This bomb is particularly useful for decompositions of refractory samples for micro- and semimicro-analysis. Temperatures of 400–450° and pressures estimated as great as 6000 p.s.i. were maintained in the bomb for...
Movements of hatchery-reared lake trout in Lake Superior
Richard L. Pycha, William R. Dryer, George R. King
1965, Journal of the Fisheries Research Board of Canada (22) 999-1024
The history of stocking of lake trout (Salvelinus namaycush) in the Great Lakes is reviewed. The study of movements is based on capture of 24,275 fin-clipped lake trout taken in experimental gill nets and trawls and commercial gill nets. Yearling lake trout planted from shore dispersed to 15-fath (27-m) depths...
Length-weight relationship of northern pike, Esox lucius, from East Harbor, Ohio
Edward H. Brown Jr., Clarence F. Clark
1965, Transactions of the American Fisheries Society (94) 404-405
The northern pike is one of Ohio's largest game fish but is well known to comparatively few anglers. Large numbers of the big fish spawn in the Ohio marshes adjacent to Lake Erie. Movements related to spawning reach a peak in late March or early April. Later the spawning population...
Food of lake trout in Lake Superior
William R. Dryer, Leo F. Erkkila, Clifford L. Tetzloff
1965, Transactions of the American Fisheries Society (94) 169-176
Stomachs were examined from 1,492 lake trout and 83 siscowets collected from Lake Superior. Data are given on the food of lake trout of legal size (17 inches or longer) by year, season, and depth of water, and on the relation between food and size among smaller lake trout. Fish...
