Effective flow-through vacuum degasser for fish hatcheries
J. T. Fuss
1983, Aquacultural Engineering (2) 301-307
Since the fry of certain species of fish cannot tolerate even slight amounts of supersaturation, their water supplies must be degassed. Gas content can be reduced to subsaturated, sublethal levels by passing it through the vacuum degasser described here. The system includes a low-cost, flow-through unit easily capable of degassing...
Serological comparison of selected isolates of Aeromonas salmonicida ssp. Salmonicida
G.B. Hahnel, R. W. Gould, E.S. Boatman
1983, Journal of Fish Diseases (6) 1-11
Eight isolates of Acronionus salmonicida ssp. salmonicida were collected during furunculosis epizootics in North American Pacific coast states and provinces. Both virulent and avirulent forms of each isolate, confirmed by challenge and electron microscopy, were examined. Serological comparisons by cross-absorption agglutination tests revealed no serological differences between isolates. Using...
Factors affecting dietary requirement and deficiency signs of L-tryptophan in rainbow trout
H. A. Poston, G. L. Rumsey
1983, Journal of Nutrition (113) 2568-2577
Two experiments were conducted to determine the concentration of dietary tryptophan needed for optimal growth and survival of fingerling rainbow trout (Salmo gairdneri), to characterize signs of tryptophan deficiency, and to ascertain the effects of niacin on deficiency signs. Test diets containing either hydrolyzed or intact casein were fed with...
Growth and survival of Atlantic salmon fed semimoist or dry starter diets
C. A. Lemm
1983, Progressive Fish-Culturist (45) 72-75
Growth and survival were compared for first‐feeding fry of Atlantic salmon (Salmo salar) fed a closed‐formula commercial preparation, BioDiet, or U.S. Fish and Wildlife Service high nutrient density diets 398 or 406 for 14 weeks. Growth of fry fed BioDiet for 2, 3, 4, or 6 weeks from first feeding...
Temporal patterns of seed use and availability in a guild of desert ants
Patricia Mehlhop, Norman J. Scott Jr.
1983, Ecological Entomology (8) 69-85
1Temporal patterns of seed use were studied from late winter to autumn in three species of seed-harvesting ants in the Sonoran Desert. Measures of effective foraging activity, dietary niche breadth and dietary niche overlaps were obtained each month and were tested for correlation with estimates of the...
[Book review] Ducks, geese and swans of North America
Gary L. Krapu
1983, The Auk (100) 246-248
This is the 3rd edition of the classic work "The Ducks, Geese and Swans of North America," which was first published in December 1942.  The original edition was authored by Francis C. Kortright with color plates by T. M. Shortt. An authoritative reference on North American waterfowl for many years,...
The white pelican (Pelicanus erythrorhynchos) as a host of Pelecanectes apunctatus (Acarina: Hypoderidae)
B.N. Tuggle
1983, Journal of Parasitology (69) 1083-1083
Several species of nymphs from the family Hypoderidae have been reported from pelecaniform birds (Cerny, 1969, Folia Parasit. (Praha) 16:271-274; Pence, 1972, J. Med. Ent. 9: 435-438; Pence and Courtney, 1973, J. Parasitol. 59: 711-718); however, there are no records from the white pelican, Pelecanus erythrorhynchos. I report here the...
Aspergillosis in a red-crowned crane
R. K. Stroud, R. M. Duncan
1983, Journal of the American Veterinary Medical Association (183) 1297-1298
An unusual form of pulmonary aspergillosis in a red-crowned crane (Grus japonensis) is described in this report. The major lesion is unique because it closely resembles a lesion referred to as an aspergilloma. An aspergilloma is a single large granulomatous lesion that resembles a tumor and is caused by fungi...
Outbreak of avian cholera on the wintering grounds of the Mississippi Valley Canada goose flock
R. M. Windingstad, R. M. Duncan, D. Thornburg
1983, Journal of Wildlife Diseases (19) 95-97
Avian cholera is reported for the first time in Canada geese, Branta canadensis, of the Mississippi Valley population. The disease was detected in weekly surveillance transects and was responsible to the loss of about 850 geese during the winter of 1978–1979 at localized areas in southern Illinois. Necropsies performed on 480...
Waterbird mortality from botulism type E in Lake Michigan: An update
Christopher J. Brand, Ruth M. Duncan, Scott P. Garrow, Dan Olson, Leonard E. Schumann
1983, The Wilson Bulletin (95) 269-275
Three outbreaks of botulism type E occurring in waterbirds on Lake Michigan since autumn 1976 are discussed. Natural ingestion of food containing type E toxin by Ring-billed Gulls (Larus delawarensis) and the presence of type E toxin in blood from moribund gulls were demonstrated. Concurrent presence of type C and...
Inclusion body disease of cranes: A serological follow-up to the 1978 die-off
D. E. Docherty, Renee I. Romaine
1983, Avian Diseases (27) 830-835
A herpesvirus was isolated from captive cranes involved in a 1978 die-off. Neutralizing antibody to this virus was detected in this captive population as early as 1975 and consistently thereafter through 1979. Exposure to the virus evidently occurred at least 2 1/2 years before the die-off, without causing any mortality...
Research note: Isolation of a herpesvirus from a bald eagle nestling
D. E. Docherty, R.I. Romaine, R.L. Knight
1983, Avian Diseases (27) 1162-1165
Cloacal swabs collected from wild bald eagle nestlings (Haliaeetus leucocephalus) were tested for viruses. A virus isolated from one of these samples had a lipid coat and contained DNA. Electron microscopy confirmed that it was a herpesvirus. This appears to be the first report of a herpesvirus isolation from a...
Salmonella enteritidis isolated from an eared grebe (Podiceps nigricollis)
Ruth M. Duncan, Richard K. Stroud, Louis N. Locke
1983, Journal of Wildlife Diseases (19) 63-64
The reported prevalence of salmonellosis in wild birds is relatively low, though the number of species of birds reported as having the disease or being carriers of the organism is increasing (Faddoul et al., 1966, Avian Dis. 10: 89- 94). The course of the disease in birds ranges from acute...
Atomic-absorption determination of mercury in geological materials by flame and carbon-rod atomisation after solvent extraction and using co-extracted silver as a matrix modifier
R. F. Sanzolone, T. T. Chao
1983, The Analyst (108) 58-63
Based on modifications and expansion of the original Tindall's solvent extraction flame atomic-absorption procedure, an atomic-absorption spectrophotometric method has been developed for the determination of mercury in geological materials. The sample is digested with nitric and hydrochloric acids in a boiling water-bath. The solution is made ammoniacal and potassium iodide...
