A summary of investigations of the use of hatchery-reared steelhead in the management of a sport fishery

Creator:: Wagner, Harry H. and Oregon State Game Commission
Abstract:: This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared...

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...

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...

Creator:: Demory, Robert L.
Abstract:: The market sampling program for Dover, English and petrale sole and Pacific ocean perch continued. Bottomfish landings were sampled at Astoria and Coos Bay. Dover sole research cruises were made in August 1967 and February 1968. Results on juvenile distribution are discussed. A tagging cruise for Dover sole was completed...

Investigation of the abundance and recruitment of bottomfish off Oregon, with emphasis on Dover sole: annual progress report July 1, 1966 to June 30, 1967

Creator:: Demory, Robert L.
Abstract:: The market sampling program for Dover, English, and petrale sole, and Pacific Ocean perch continued. Market conditions severely limited landings during the last quarter. A Dover sole cruise was completed in May. Data from the July 1966 Dover sole cruise plus data from two shrimp cruises (October-November 1966 and March-April...

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...

Rockfish assessment studies on Heceta Bank, Oregon, 1980-81. Sub-project annual report: October 1, 1980 to March 1, 1982

Creator:: Johnson, Steven L., Barss, William H., and Demory, Robert L.
Abstract:: From January 1980 to January 1981 approximate monthly sampling of a unique rockfish (Scorpaenidae) fishing area on Heceta Bank, Oregon was undertaken using acoustic techniques and trawling aboard chartered commercial fishing vessels. Rankings of density of fish sign observed on acoustic transects were regressed against selected environmental variables. Acoustic abundance...
