Effects of dieldrin on the growth and development of steelhead trout

Creator:: Oregon State University. Agricultural Experiment Station, Shumway, Dean L., and Chadwick, George Grete
Abstract:: Experiments were conducted to determine survival, growth, and accumulation of HEOD (major component of dieldrin) in the tissues of steelhead trout (Salmo gairdneri) embryos, alevins, and fry exposed to dieldrin concentrations ranging from 0.012 to 52 ppb. The fish were held in specially designed exposure chambers provided with continuously renewed...

An analysis of the population dynamics of selected avian species

Creator:: Henny, Charles J.
Abstract:: The impact that pesticides may have had on the mortality rates and productivity rates of non-game birds during the last 25 years was evaluated by studying the population dynamics of 16 species. A mathematical model showing the relationships between population parameters that yielded stable populations was developed. The information needed...

Creator:: Suraswadi, Plodprasop
Abstract:: The experiment was conducted at the Soap Creek farm ponds near Corvallis, Oregon. Oregon Moist Pellet and Purina Trout Chow at three different rates of feeding for each diet were used to feed fingerling channel catfish stocked at the rate of 1,000 per acre. A complete random design and Fisher's...
