Creator:: Weber, Madeleine Demaries
Abstract:: This thesis focuses upon whether stressful aspects of an organism's environment are reflected by that organism's shape. It presents an application of the powerful thin-plate spline and relative warp methods from morphometric analysis to demonstrate the overall utility of morphometrics in detecting environmental stress in an estuarine flatfish, the English...

Creator:: Barss, William H.
Abstract:: The English sole is a major contributor to Pacific Ocean trawl fisheries off the United States and Canada. Only Dover sole and sometimes petrale sole provide greater annual landings in Oregon. English sole are considered fine eating sole and usually enjoy a good market. In British Columbia, local consumers of...

Creator:: Macomber, Marcia Fraser
Abstract:: This study examined the logbook record of the Oregon trawl fishery using a geographic information system (GIS) to determine the spatial and temporal distribution of English sole, Pleuronectes vetulus. The original logbook data for the years 1981,1982,1994,1995,1996 were filtered twice to provide both a general description of trends in the...

Creator:: Stowell, Michelle A.
Abstract:: Observations of the Oregon coast’s physical oceanography over the last few decades have revealed falling dissolved oxygen levels associated with seasonal upwelling, as well as rising water temperatures. In extreme cases, these changes have been associated with die-offs, redistribution, and decreased abundance and diversity of benthic fish and invertebrates. Many...

Full Text:: Condition of Juvenile English Sole (Parophrys vetulus) from the Oregon Coast Abstract approved

Creator:: Hayden, Thomas R.
Abstract:: English sole is a major contributor to Oregon and Washington groundfish resources. In accordance with the continued trend of increasing fishing effort, in 1975 Oregon State University Sea Grant funded an extensive groundfish research program: the Pleuronectid Project. The purpose was to provide information to assist resource management agencies. This...
Resource Type:: Masters Thesis

Creator:: Bancroft, Morgan P.
Abstract:: In the past two decades, occurrences of summertime upwelling-driven low dissolved oxygen (DO) events, or hypoxia, have increased along the northeast Pacific coast. If hypoxic events are severe enough to cause marine species mortality, the areas affected are often called "dead zones." In 2002 and again in 2006, the events...
