Female homogamety in grass carp (Ctenopharyngodon idella) determined by gynogenesis
Jon G. Stanley
1976, Journal of the Fisheries Research Board of Canada (33) 1372-1374
Gynogenesis occurred in eggs of grass carp (Ctenopharyngodon idella) treated with X-irradiated milt from goldfish (Carassius auratus). Gynogenetic offspring were females, which indicates functional female homogamety in grass carp. Five of these gynogenetic fish were used as an egg source for a second generation of artificially gynogenetic fish. The percentage...
Utilization of satellite data for inventorying prairie ponds and lakes

1976, Photogrammetric Engineering and Remote Sensing (42) 685-694
By using data acquired by LANDSAT-1 (formerly ERTS- 1), studies were conducted in extracting information necessary for formulating management decisions relating to migratory waterfowl. Management decisions are based in part on an assessment ofhabitat characteristics, specifically numbers, distribution, and quality of ponds and lakes in the prime breeding range. This...
A relationship between avian carcasses and living invertebrates in the epizootiology of avian botulism
Ruth M. Duncan, Wayne I. Jensen
1976, Journal of Wildlife Diseases (12) 116-126
A survey of the sources of Clostridium botulinum type C toxin possibly utilized as food by aquatic birds in an epizootic area of avian botulism in northern Utah showed that living aquatic and terrestrial invertebrates normally found in close association with dead, decomposing birds commonly carried the toxin. Of 461 samples associated...
An outbreak of erysipelas in eared grebes (Podiceps nigricollis)
Wayne I. Jensen, Sally E. Cotter
1976, Journal of Wildlife Diseases (12) 583-586
An outbreak of erysipelas killed an estimated 5,000 aquatic birds on Great Salt Lake (Utah) in late November, 1975. Although several thousand ducks and gulls were using the lake, at least 99 percent of the victims were eared grebes. A hypothetical explanation for the selective mortality is offered....
Antimycin: Uptake, distribution, and elimination in brown bullheads (Ictalurus nebulosus)
D.P. Schultz, P.D. Harman
1976, Journal of the Fisheries Research Board of Canada (33) 1121-1129
Radioactive antimycin was readily taken up in bile and tissues of brown bullheads (Ictalurus nebulosus) exposed to 0.045 μg/ml of 14C-antimycin for as long as 48 h. Bile contained the most and blood the least radioactivity at all sampling periods. The highest concentration of 14C-antimycin in muscle was 0.12 μg/g, after 12 h of exposure. The...
Avian botulism epizootiology on sewage oxidation ponds in Utah
Daniel W. Moulton, Wayne I. Jensen, Sondra K. Stewart
1976, Journal of Wildlife Management (40) 735-742
In the microenvironment concept of avian botulism epizootiology, it is hypothesized that invertebrate carcasses may serve both as a substrate for toxin production by Clostridium botulinum type C and as a vehicle for toxin transmission to water birds. We field-tested that hypothesis by attempting to induce botulism in wing-clipped mallard...

Fine structure of an unidentified protozoon in the epithelium of rainbow trout exposed to water with Myxosoma cerebralis
S.B. Daniels, R. L. Herman, C.N. Burke
1976, Journal of Protozoology (23) 402-410
An intracellular protozoon was discovered in the epithelium of young rainbow trout (Salmo gairdneri) exposed for as short a time as 1 hr to water known to contain infective stages of Myxosoma cerebralis. Light- and electron-microscopic examination of this tissue revealed what appeared to be a proliferative stage (presumptive schizont) of a...
Optimum level of dietary biotin for growth, feed utilization, and swimming stamina of fingerling lake trout (Salvelinus namaycush)
H. A. Poston
1976, Journal of the Fisheries Research Board of Canada (33) 1803-1806
Triplicate lots of fingerling lake trout (Salvelinus namaycush) held at 9 C for 20 wk were fed a semipurified basal diet supplemented with 1% spray-dried egg white or d-biotin at concentrations of 0.1, 0.5, 1.0, or 5.0 ppm. Trout fed the basal diet, either alone or with egg white, grew more slowly and...
Comparison of techniques for stabilizing hemoglobins of rainbow trout (Salmo gairdneri) during frozen storage
G. L. Reinitz
1976, Comparative Biochemistry and Physiology, Part B: Comparative Biochemistry (55) 357-358
1. The stability of hemoglobin of rainbow trout under frozen conditions in oxyform, carboxyform, and cyanometform was examined.2. Carboxyhemoglobin retained its original electrophoretic banding pattern after 14 days of frozen storage, whereas oxyform and cyanometform hemoglobins did not.3. Banding patterns changed in some samples in all treatment groups after 21...

Vitamin E and selenium interrelations in the diet of Atlantic salmon (Salmo salar): Gross, histological and biochemical deficiency signs
Hugh A. Poston, G. F. Combs Jr., Louis Leibovitz
1976, Journal of Nutrition (106) 892-904
Either simultaneous or separate dietary deficiencies of vitamin E and selenium in Atlantic salmon during first 4 weeks of feeding caused twice the mortality shown in fish fed both supplemental vitamin E (0.5 IU/g dry diet) and selenium (0.1 µg/g). Subsequent dietary repletion with both vitamin E and selenium significantly...
Glomerular mesangial fibrosis in hatchery-reared rainbow trout (Salmo gairdneri)
D.E. Hinton, R.T. Jones, R. L. Herman
1976, Journal of the Fisheries Research Board of Canada (33) 2551-2559
Light and electron microscopic studies were performed on tissues of hatchery-reared rainbow trout (Salmo gairdneri) having a disease of currently unknown etiology with external symptoms of severe edema which causes increased mortality rate. Comparison with unaffected trout tissues revealed loss of cellularity in glomerular tufts with a replacement of mesangial...
Influence of water temperature on gill sodium, potassium-stimulated ATPase activity in juvenile coho salmon (Oncorhynchus kisutch)
W.S. Zaugg, L. R. McLain
1976, Comparative Biochemistry and Physiology, Part A: Physiology (54) 419-421
1. Gill sodium, potassium-stimulated ATPase activity was determined from December to July in gills of yearling coho salmon (Oncorhynchus kisutch) maintained at four temperatures, 6, 10, 15 and 20°C.2. Compared to fish held at 6°C, elevation in ATPase activity and the associated parr-smolt transformation were accelerated in fish at...
Change in methylene blue active substances and chloride levels in streams in Suffolk County, New York, 1961-1976
Stephen E. Ragone, August A. Guerrera, W.J. Flipse Jr.
1976, Open-File Report 76-600
Since 1961, concentrations of methylene blue active substances and chloride were measured in samples collected at 67 sampling stations on 44 streams in Suffolk County, Long Island, New York. Changes in the concentrations of these constituents and calculated chloride/methylene blue active substances ratios are reported. Although many factors--the 1962 to...
Earthquake prediction; fact and fallacy
R.N. Hunter
1976, Earthquake Information Bulletin (USGS) (8) 24-27
Earthquake prediction is a young and growing area in the field of seismology. Only a few years ago, experts in seismology were declaring flatly that it was impossible. Now, some successes have been achieved and more are expected. Within a few years, earthquakes may be predicted as routinely as the...
Is there a periodicity in the occurrence of earthquakes?
R.N. Hunter
1976, Earthquake Information Bulletin (USGS) (8) 4-7
Various periodicities have been suspected in earthquake activity, but none has yet been proved. In his classic text on seismology, K.E Bullen remarked that small but discernable "trigger" forces, such as tidal effects, temperature changes or barometric changes, have been thought to act as "last straw" phenomena when the earthquake...
