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...
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...
An elutriation apparatus for macroinvertebrates
Joseph M. Worswick Jr., Michael T. Barbour
1974, Limnology and Oceanography (19) 538-540
An inexpensive hydropneumatic apparatus screens macroinvertebrates from bottom samples containing silt, mud, or clay. The elutriator, an acrylic cylinder with screened windows, cemented on an upright plastic funnel, retains benthic fauna while the sediment is washed away. The apparatus yields clean samples and has reduced the time required to sort...
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...

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...
