Serological diagnosis of corynebacterial kidney disease of salmonids
P. K. Chen, G. L. Bullock, H. M. Stuckey, A.C. Bullock
1974, Journal of the Fisheries Research Board of Canada (31) 1939-1940
An immunodiffusion test is described which provides a rapid, sensitive, and definitive diagnosis of corynebacterial kidney disease of salmonid fishes. Specific precipitin lines are formed within 24 h when rabbit antiserum is reacted with kidney disease cell suspensions or internal tissue homogenates containing the specific bacterium. No precipitin lines are formed...
Short-term fate of dietary dieldrin in the digestive tract of juvenile lake trout (Salvelinus namaycush)
Donald J. Stewart, Roy A. Stein
1974, Bulletin of Environmental Contamination and Toxicology (11) 563-566
Short-term fate of dietary dieldrin in the digestive tract of fishes is poorly known. Studies of the uptake, distribution, and elimination of chlorinated hydrocarbons have suggested that uptake or degradation is rapid in the intestine (GROSS 1969; MACEK et al. 1970; GRZENDA et al. 1970, 1971). The present study was...
Effect of acclimation temperature and heat shock on vulnerability of fry of lake whitefish (Coregonus clupeaformis) to predation
Thomas G. Yocom, Thomas A. Edsall
1974, Journal of the Fisheries Research Board of Canada (31) 1503-1506
Fry of lake whitefish (Coregonus clupeaformis) acclimated to 10, 15, and 18 C were exposed to temperatures of 24.5, 25, and 28 C for 1 min and then immediately returned to water at their acclimation temperature, in test tanks containing yearling yellow perch (Perca flavescens). The number of attacks on the fry and...
The effects of environmental stress on outbreaks of infectious diseases of fishes
S. F. Snieszko
1974, Journal of Fish Biology (6) 197-208
Infectious diseases of fishes occur when susceptible fishes are exposed to virulent pathogens under certain environmental stress conditions. Very little research has been carried out to show the effect of pollution on outbreaks of infectious diseases of fishes. Therefore, examples taken from the literature were selected and reviewed to show...
Mammals and birds
James C. Bartonek, R. Elsner, F.H. Fay
E.J. Kelley, Donald W. Hood, editor(s)
1974, Book chapter, Probes: a prospectus on processes and resources of the Bering Sea shelf, 1975-1985
New concepts regarding the production of waterfowl and other game birds in areas of diversified agriculture
H.K. Nelson, Harold F. Duebbert
1974, Book chapter
Many concepts regarding breeding ecology of waterfowl and the influences of environmental factors on annual production have changed in the past 20 years. These influences are especially pronounced in the prairie region of central North America where agriculture becomes more intensive each year. The principal task assigned to this Research...

W. L. Halvorson, C.G. Dawson
1974, Book chapter, Coastal and Offshore Environmental Inventory, Cape Hatteras to Nantucket Shoals.

Habitat management considerations for prairie chickens
L.M. Kirsch
1974, Wildlife Society Bulletin (2) 124-129
Lack of nesting and brood rearing habitat appears to be the universal limiting factor for prairie chickens (Tympanuchus cupido pinnatus) throughout their range. Grasslands are essential to prairie chickens, but vary widely in quality and thus in their ability to support prairie chickens. High-quality habitat is grassland providing residual vegetation...
Hazards to animals feeding on blackbirds killed with 4-aminopyridine baits
E. W. Schafer Jr., R.B. Brunton, Norman F. Lockyer
1974, Journal of Wildlife Management (38) 424-426
Red-winged blackbirds (Agelaius phoeniceus) killed by ingesting cracked corn baits treated with 3 percent 4-aminopyridine, or by oral doses of 4-aminopyridine, were fed to canines, laboratory rats (Rattus norvegicus), black-billed magpies (Pica pica), and three species of hawks. The test animals consumed the equivalent of up to 3.4 LD50 doses...
