"Letters and newspaper articles concerning the low quantity and poor quality of Dungeness crabs in Nehalem Bay have been frequently received by the Oregon Fish Commission. Popular opinion usually places the blame for the lack of legal-sized bay crabs in the Nehalem estuary upon the adjacent commercial crab fisheries, A...
Estuaries provide juvenile salmonids with highly productive feeding grounds, refugia from tidal fluctuations and predators, and acclimation areas for smoltification. However, these dynamic, fluctuating salinity environments may also be physiologically stressful to growing juvenile fish. In order to evaluate the costs and benefits of estuarine marshes to juvenile Chinook salmon,...
In 1971 the Fish Commission of Oregon conducted a comprehensive study of the recreational use of marine food fish, shellfish, and other miscellaneous invertebrates in 16 Oregon estuaries. From March 1 through October 31, 1971, boat and shore anglers and tideflat users were interviewed for catch, effort, and origin data...
Multibeam sonar data was collected on Nehalem Bank, off of the Oregon Coast with the purpose of increasing the spatial resolution of our knowledge of the area and delineating seafloor habitats. The system used was the Kongsberg Simrad EM-300 operating at 30 kHz. The data set collected includes both topographic...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...

Abnormal, large, possibly neoplastic cells from two Ostrea /urida have been successfully labeled with tritiated thymidine, and thus, for the first time, data are available for analyzing a presumptive invertebrate proliferative disorder. Large numbers of labeled atypical cells (AC) were uniformly distributed throughout the connective tissue (CT) underlying the gills,...
Side-scan sonar records in Oregon's Coos Bay estuary navigation
channels were obtained at intervals of two to three months during the
November 1974 - October 1975 time period from Coos Bay Channel Mile
11+50 to 15+20, and from a reach in the Marshfield Channel. A limited
side-scan survey effort was...
During the six-month period of July through December, 1966,
a study of animals inhabiting laminarian holdfasts in Yaquina Bay,
Oregon, was carried out to determine what animals live in this habitat
and to gain some idea of the factors which influence their presence
and distribution. This study deals with yet...
