Clam-Oyster-Abalone Larval Rearing: Annual Report July 1, 1970 to June 30, 1971 - Lukas, Gerald; Gibson, Gary; Oregon. Fish Commission. Research Division (Oregon Fish Commission, 1971)
Reports on studies of spawning and larval rearing of Manila littleneck clams, native littleneck clams, butter clams and gaper clams, including field work. "Field studies comparing growth and survival of laboratory-reared and imported Pacific and Kumamoto oysters were completed. We continued studies comparing various methods of oyster culture in Yaquina Bay. Winter survival of laboratory-reared oyster spat was determined. Adult red abalone were obtained for spawning purposes." (p.1) Covers July 1, 1970 to June 30, 1971.

Oyster Mortality Study: Annual Report April 1, 1969-March 31, 1970 - Gibson, Gary; Oregon. Fish Commission; U.S. Fish and Wildlife Service, (Fish Commission of Oregon, 1970)
"Objectives of Oregon's oyster mortality study for the past year included monitoring oyster mortality in Yaquina, Tillamook, and Coos bays, obtaining hydrographic data in Yaquina Bay; and furnishing oysters to the University of Washington and the Bureau of Commercial Fisheries (BCF) in Oxford, Maryland, for histological examination. Other activities included (1) determining seasonal growth of Pacific oysters in Yaquina Bay, (2) cooperating with the BCF Oxford laboratory on a study of the neoplastic disease in native oysters, Ostrea lurida, and (3) obtaining information on the longevity of Pacific oysters, Crassostrea gigas." (Introduction) During the study year, 8.6% of Pacific oysters in Yaquina Bay and 26.5% of the native Olympia oysters there died.

Shellfish investigations. Progress report #39. April 1, 1967 - March 31, 1970 - Snow, C. Dale; Gaumer, Tom; Demory, Darrel; Neilsen, John R.; Osis, Laimons; Phibbs, Duane; Gibson, Gary (Shellfish Investigations Progress Report, 1970)
This document is a report on shellfish investigations from April 1967 to March 1970. It includes the results of bay clam surveys for Yaquina, Siuslaw, and Umpqua bays, and harvest numbers for razor clams in both personal-use and commercial fisheries. This report also contains a summary of beach surveys for six razor clam beaches, and the results of two new methods of ragging razor clams. In crab work, the report discusses problems with tagging, condition sampling, and regulatory issues. The report discusses rearing of red abalone, federal programs for oysters, and concludes with a summary of work with intertidal nonfood animals.

Oyster Mortality Study: Annual Report April 1, 1968-March 31, 1969 - Gibson, Gary; Oregon. Fish Commission; U.S. Fish and Wildlife Service, (Fish Commission of Oregon, 1969)
"Objectives of Oregon's Oyster Mortality study for the year ending March 1969 were similar to those of the first 2 years of the program: (1) to monitor oyster mortality in Yaquina, Tillamook and Coos bays, (2) to collect hydrographic data in Yaquina Bay and (3) to furnish oysters to the University of Washington for comparative histological examination. Additional work was done on the seasonal growth of Pacific oysters, the survival and growth of native oysters from spat and low salinity tolerance of adult native oysters." (Introduction)

"Although Oregon has been relatively free from any major oyster mortality a monitoring program has been established with the basic objectives being to: (1) monitor mortalities; (2) collect environmental data; and (3) furnish oyster from a disease-free area for histological examination." (Introduction) Includes hydrographic data from test plots in Yaquina, Tillamook and Coos Bays, size and condition data for native Olympia oysters as well as Pacific oysters and a record of oyster mortalities for Yaquina Bay.

Oyster Mortality Study: Hydrographic Data for Yaquina, Coos, and Tillamook Bays - Gibson, Gary; Snow, C. Dale; Oregon. Fish Commission; U.S. Fish and Wildlife Service, (Fish Commission of Oregon, 1967)
Accompanies Oyster Mortality Study, 1966/1967 report. "Tables 1 through 5 give salinity, temperature, dissolved oxygen, turbidity, and pH data for Yaquina Bay while Table 6 gives temperature and salinity for Tillamook and Coos bays.""This information appears in the quarterly and annual reports as either mean values or ranges, but is presented in the following tables as collected. It is hoped that this information can be used for comparison in areas where high oyster mortalities occur." (from the Introduction)
