During the past 10 years the embryos and larvae of oysters and some species of clams have been employed to quickly assess the biological effects of various substances in marine water samples. The best materials have included some insecticides, herbicides, antibiotics, detergents, a variety of other compounds, and a few...

Fisheries Laboratory during 1952, in the rearing of the native Pacific Coast oyster, Ostrea lurida Carp., in small containers. The decline of the oyster fishery in Yaquina Bay, Oregon, has been attributed in part to the lack of adequate spat-falls. Investigations were begun in 1947 to devise methods of artificially...
This report is a brief overview of the status of Oregon’s oyster aquaculture in the mid to late 1970s, including discussions of trends in harvests and research into oyster breeding.
Beginning in the late 1960s and throughout the past decade, unusual, perhaps neoplastic, large cells with rather consistent characteristics were described in mussels, clams, and oysters from several bays in the United States and the United Kingdom. The large, characteristic cells are thought by many workers to be abnormal leukocytes...
