  • A mendelian study of Crassostrea gigas

    Creator:
    Smoker, Janet Van Dusen
    Abstract:
    The genotype frequencies of one-year-old oyster spat (Crassostrea gigas) from parents of known genotype, are compared to the frequencies expected with Mendelian inheritance. The genotypes are characterized at three enzyme loci, Aspartate amino-transferase (AAT), Phosphohexose isomerase (PHI) and Leucine aminopeptidase (LAP), and a general protein locus. In this study expression...

  • Comparative values of corn and corn cannery waste silages for milk production in dairy cattle

    Creator:
    Meyers, George Henry
    Abstract:
    The production level of dairy cows fed corn cannery waste silage was investigated during a 305 day lactation study. Eighteen Holstein cows were paired according to their probable producing ability and field corn silage was fed to the control pairmates, Forage analyses (DM, CP, CF, and nitrates) were determined on...

  • Application of linear programming techniques to ration formulation for lambs and steers

    Creator:
    Macy, Gregg Harlan
    Abstract:
    The object of this study was to analyze the application of linear programming techniques to ration formulation for feedlot lambs and steers. Three rations for feeder lambs were designed to study the application of linear programming techniques under varying ration constraints. Rations studied were as follows: iso-caloric rations with three...

  • The copepods in a collection from the southern coast of Oregon, 1963

    Creator:
    Lee, Wen-yuh
    Abstract:
    Plankton samples for this present study were collected from an area off the southern Oregon coast, extending westward to about 83 kilometers offshore. Over this sampling area, 41 species of adult copepods were identified, including representatives of 26 genera and 17 families. The total abundance averaged 550/m³. Population densities of...

  • Growth of a sea urchin, Allocentrotus fragilis, at different depths off the Oregon coast

    Creator:
    Sumich, James L.
    Abstract:
    Allocentrotus fragilis (Jackson) was obtained from six stations at depths of 100 to 1260 m on the continental shelf and upper slope off Newport, Oregon. Ages and growth rates of A. fragilis were determined by two methods: 1) A procedure was developed to make growth zones of the skeletal test...

    Abstract:
    This study of the immediate, localized effects of a small dredging operation on the benthic invertebrate community in the shipping channel of Coos Bay, Oregon, was designed: 1) to measure the extent of the physical removal of benthic macro- and meiofauna by hopper dredging; 2) to record the subsequent benthic...

  • The activity pattern of Diadora aspera

    Creator:
    Boese, Bruce Leon
    Abstract:
    Diadora aspera is an intertidal keyhole limpet found in the mid-tidal zone. Its activity pattern was estimated under laboratory conditions using time-lapse-photography and manometric determinations of oxygen consumption. Statistical and computer analyses of the photographic data suggest the presence of both a 24 hour and a 12-13 hour rhythm in...

  • The ghost shrimp, Callianassa californiensis Dana, 1854, in Yaquina Bay, Oregon

    Creator:
    McCrow, Lynne Tucker
    Abstract:
    The life cycle of Callianassa californiensis Dana, 1854, was studied in the tidal estuary, Yaquina Bay, Oregon. At this latitude it is largely restricted to intertidal sandy mudflats under predominately marine influence. Salinity and temperature appear to determine its distribution to a greater extent than does sediment type. Vertical movement...

    Creator:
    Canon, Jose Raul
    Abstract:
    The present work is an attempt to correlate information collected in the northern part of Chile with the anchoveta distribution and its fluctuation. This information was collected over a three year period (November 1967 to November 1970) by the Instituto de Fomento Pesquero, Chile (IFOP). The first and second part...
