"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.
