Investigation of the abundance and recruitment of bottomfish off Oregon, with emphasis on Dover sole: annual report July 1, 1969 to June 30, 1970

Creator:: Demory, Robert L.
Abstract:: Market sampling continues. Most samples have been aged. Several cruises were made during fiscal year 1969-70. The deep water survey for Dover sole yielded questionable results. Neither spawning concentrations nor concentrations of males were located. Calculations of year class strength for English sole showed that the 1961 year class was...

The Dover sole

Creator:: Demory, Robert
Abstract:: The Dover sole has been the most important flatfish in Oregon's trawl fishery since its beginning in 1938. At that time the fish was called slime sole, because the animal produces great quantities of the stuff. The term Dover sole apparently comes from the north Atlantic where a similar creature...

Investigation of the abundance and recruitment of bottomfish off Oregon, with emphasis on Dover sole: annual report July 1, 1968 to June 30, 1969

Creator:: Demory, Robert L.
Abstract:: Market sampling continues. Aging structures have been read, and all aging work is current. Age composition of Dover sole shows that stocks off Coos Bay are fully recruited 1-2 years later than stocks off the Columbia River. Age composition of English sole reveals a very strong 1961 year class. The...

Characterizing the Spread and Consequences of Mycoplasma ovipneumoniae on Bighorn Sheep (Ovis canadensis) in the Northern Basin and Range Ecosystem

Creator:: Spaan, Robert S.
Abstract:: North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...
