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...

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...

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...

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...

Creator:: Wirosoebroto-Hartadi, Retno Widaningroem
Abstract:: Rainbow trout (Salmo gairdneri) and bluegill (Lepomis macrochirus) were exposed to flows of water containing low DO concentrations produced by bubbling nitrogen through the water. Abrupt exposure of fish to critical DO concentrations (The standard dose response) and by a more gradual changing of DO levels (The "stepdown" approach) were...

Creator:: Schuler, Carol Ann, 1946-
Abstract:: Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and other minerals from farmland in the San Joaquin Valley of California. Aquatic plants and invertebrates were sampled at Kesterson in May, August, and December of 1984. The reservoir supported a different biota and lower species diversity than...
