Retention of lead during oxidative ashing of selected naturally occurring carbonaceous substances
F. Cuttitta, J.J. Warr Jr.
1958, Geochimica et Cosmochimica Acta (13) 256-259
The amount of lead retained in the ash of lead-bearing carbonaceous material is essentially independent of the method of ashing. Samples containing lead in the range of 0.00X to 0.X per cent were ashed by ignition in a high-oxygen atmosphere and were also wet-ashed. The lead in the ash was...
Some natural variations in the relative abundance of copper isotopes
E. C. Walker, F. Cuttitta, F. E. Senftle
1958, Geochimica et Cosmochimica Acta (15) 183-194
The relative isotopic abundance of copper has been measured in a number of minerals and a few plant materials. Suites of samples from Michigan and the Colorado Plateau have been examined in more detail to determine if local variations due to isotopic exchange or diffusion could be found. The relative...

Suggestions for reduction of natural mortality in fish populations
S. F. Snieszko
1958, Transactions of the American Fisheries Society (87) 380-385
Illness, in fish as well as in other animals, when caused by an infectious disease, is often not the result of infection with pathogens alone. In many cases the pathogens and hosts can exist side by side without development of disease symptoms. Such symptoms, with resulting illness or death,...
Fishery management problems and possibilities on large southeastern reservoirs
John W. Parsons
1958, Transactions of the American Fisheries Society (87) 333-355
Principal problems concerning the fisheries of large reservoirs in the Southeast are: inefficient and highly selective exploitation of fish stocks, and protection and reclamation of damaged or threatened fisheries in tailwaters and tributary streams. Seven mainstream reservoirs on which data are available support an average angling pressure of 4.9 trips...

Isolation and identification of an ester from a crude oil
H.F. Phillips, Irving A. Breger
1958, Geochimica et Cosmochimica Acta (15) 51-56
A dioctylphthalate has been isolated from a crude oil by means of adsorption column chromatography. The ester was identified by means of elemental analysis, refractive index, and its infra-red absorption spectrum. Saponification of the isolate and examination of the resultant alcohol by means of infrared absorption spectra led to the...

Some myxosporidia found in Pacific Northwest salmonids
W. T. Yasutake, E. M. Wood
1957, Journal of Parasitology (43) 633-642
During the histological examination of a group of wild and hatchery salmonids undescribed sporazoans were frequently observed. This was not unexpected, since Myxosporidia are typical fish parasites (Kudo, 1920). Myxidium were observed in kidney tubules, Cholromyxum in glomeruli, and Myxobous in the spinal cord and on epidermal scales. The present...
Teratological hermaphroditism in the chum salmon Oncorhynchus keta (Walbaum)
J. R. Uzmann, M. N. Hesselholt
1957, Progressive Fish-Culturist (20) 191-192
The anomalous condition of hermaphroditism appears to be no less rare in fish than in other normally dioecious animals. Previous records of bisexuality' in the Pacific salmons, Oncorhynchus spp., are few in number despite the intensive study accorded this group. Rutter (1902) reported the condition in two king salmon (O....
New host and locality record for Triaenophorus crassus forel (Cestoda: pseudophyllidea)
J. R. Uzmann, M. N. Hesselholt
1957, Journal of Parasitology (43) 205-208
The adult form of Triaenophorus crassus Forel, 1868 (= T. robustus Olsson, 1893; = T. tricuspidatus morpha megadentatus Wardle, 1932) occurs as an intestinal parasite in the pike, Esox lucius L., a holarctic species of wide distribution. Preliminary life-history stages include procercoid development in copepods of the genus Cyclops followed...

Some problems of private trout hatchery operators
Robert R. Rucker
1957, Transactions of the American Fisheries Society (87) 374-379
Disease, nutritional, and environmental problems in commercial production of trout are discussed, including mortality and age of spawners, copepod and gyrodactylid infections, suitable water temperatures, diseases (especially red mouth and back peel) and inspection of fish. It is concluded that experiences with hatchery procedures have varied greatly and often the...

E. M. Wood, W. T. Yasutake, A.N. Woodall, J.E. Halver
1957, Journal of Nutrition (61) 465-478
Salmonids reared under artificial conditions show marked consistent differences in body composition in comparison with wild salmonids. Protein and mineral levels are lower and lipid values are higher in hatchery fish than in wild fish. As the period of artificial rearing is increased, these differences become more extreme....

E. M. Wood, W. T. Yasutake, A.N. Woodall, J.E. Halver
1957, Journal of Nutrition (61) 479-488
In 69 production diets fed to hatchery salmonids, there was a wide variation in the ingredients of the diets and in their content of protein, fat, carbohydrate and ash. There was a close correlation between the body composition of hatchery-raised fish and the composition of the diets fed....
Acute sulfamethazine toxicity in young salmon
E. M. Wood, W. T. Yasutake, Harlan E. Johnson
1957, Progressive Fish-Culturist (19) 64-67
Adverse effects from the medication of fish diseases with sulfonamides have been reported by several workers. A decreased growth rate (Gutsell and Snieszko 1949, Snieszko and Wood 1955), the production of drug resistant strains of pathogens (Snieszko 1952), sterility and kidney damage (Wood et al., 1955), and mortalities (Johnson and...
Histopathology of fish. V. Gill disease
1957, Progressive Fish-Culturist (19) 7-13
Possibly no single disease accounts for greater annual mortality than gill disease. Apparently endemic in many hatcheries, the disease is characterized by periodic sharp upsurges which are sometimes correlated with rising water temperatures, excessive foreign matter in the water (Wales and Evins 1937), or borderline nutritional conditions....
