Effects of X- and gamma irradiation on the juvenile pacific oyster, Crassostrea gigas

Creator:: Trenholm, Steve Ray
Abstract:: Two separate studies were conducted during this research project. Oysters were irradiated with 500 and 1000 rads and 5, 10, 20, 50, 75, 100, 150, and 200 krads in the first study in order to determine the effects of ionizing radiation on survival and growth rates. Two periods of high...

The effects of concentration and particle size of suspended materials on growth and condition of the Pacific oyster (Crassostrea gigas)

Creator:: Wilson, William Joseph
Abstract:: The effects of exposure to suspended silt, kaolin and fuller's earth on growth and condition of Pacific oysters, 16 months of age, were studied. The exposure apparatus maintained a continuous flow of turbid water through chambers containing test oysters. Additional studies measured the filtration rates of oysters exposed to suspended...

Cardiovascular and respiratory responses of the ghost shrimp, Callianassa californiensis Dana, to the pesticide carbaryl and its hydrolytic product 1-naphthol

Creator:: Estes, Patricia S.
Abstract:: Many environmental factors influence cardiovascular and respiratory activities of crustaceans. The effects of natural stressors (hypoxia, low salinity, high temperature) have been well studied, but the effects of pollutants upon these two organ systems have received less attention. The presence of the pesticide carbaryl (Sevin, Union Carbide, Inc.) and its...

Growth and production of salmonids exposed to a stabilized Kraft mill effluent in experimental stream channels

Creator:: Mower, Barry Francis
Abstract:: The growth and production of brown trout, Salmo trutta Linnaeus, exposed to a concentration of 0.65 mg/l BOD (4.1 percent by volume) stabilized kraft mill effluent (KME) were studied from October 1973 until May 1974 in three experimental stream channels located near a kraft mill in Albany, Oregon. Growth rate...

Predator-prey interactions under the influence of ammonia

Creator:: Woltering, Daniel Mark
Abstract:: Predator-prey interactions, as measured by the consumption and growth rates of a predator (Micropterus salmoides) and by the observed activities of both predator and prey (Gambusia affinis), were found to be sensitive to sublethal levels of ammonium chloride (reported as unionized ammonia NH₃). One bass and 15, 30, 60 or...

The dynamics of exploited guppy populations exposed to dieldrin

Creator:: Liss, William J.
Abstract:: Sixteen populations of guppies (Poecilia reticulata) were established in laboratory aquariums. Eight populations were exposed to dieldrin at a mean concentration of 0.525 ppb in the water and 2.11 ppm in the food, tubificid worms. Eight populations received control water and food. All populations were fed three grams of tubificid...

BOD and toxicity of log leachates

Creator:: Atkinson, Sheridan William
Abstract:: A series of log storage experiments were conducted to determine whether leachates derived from water storage of logs are acutely toxic to fish. Log segments approximately 18 inches long and 16 inches in diameter were stored in tanks and held submerged for a period of 7 days. The holding water...

Influence of 2,4-dichlorophenol on the flavor of fish

Creator:: Palensky, John R.
Abstract:: A laboratory investigation was performed to determine the influence of 2,4-dichlorophenol on the flavor of fish. The study was conducted at the Oak Creek Fisheries Laboratory of the Department of Fisheries and Wildlife, Oregon State University. The three experimental apparatus used in this study were designed to deliver 250 ml/min...

The Willamette River fishes as biological indicators of pollution

Creator:: Noble, Richard Earl
Abstract:: An investigation of the fishes of the Willamette River and three of its larger tributaries was made during July, August, September, and November of 1951, to ascertain the possibility of using them as bio-indices of pollution. Thirteen stations were established on the Willamette River and tributaries. These stations were selected...
