The purpose of this report is to describe a large tumor complex that was found protruding into the pericardial cavity of a single Ostrea lurida from Yaquina Bay, Oregon.
The Pacific Oyster (Crassostrea gigas) is one of the most economically and ecologically significant shellfish species worldwide. In the Pacific Northwest United States (PNW), the sustainability oyster stocks is increasingly threatened by ocean acidification (OA), which has had significant negative effects on the aquaculture industry in this region over the...
This brief one page report was presumably written by R.E. Dimick, a prominent Oregon State University professor who studied the oysters of Yaquina Bay, Oregon during the 20th century. This report details human use of the native oyster through 1923.
The Olympia oyster is a foundation species that increases habitat structure for associate species in estuarine systems of the Pacific Coast of North America (Kimbro & Grosholz, 2006). This oyster provides ecosystem services in the form of water filtration (zu Ermgassen et al., 2013), habitat for commercially valuable species such...
Marine bivalves are globally recognized as ecologically and commercially valuable species and, for over a century, researchers have been studying their feeding, digestion and other related physiological processes. These studies have shown that marine bivalves have complex feeding and particle processing behaviors to maximize growth in dynamic environmental conditions. Additionally,...

CHAPTER 2 COMPARATIVE FEEDING PHYSIOLOGIES AND PARTICLE
PROCESSING OF THE OLYMPIAOYSTER
Unpublished manuscript that was distributed locally and is cited in contemporary publications. Describes oyster grounds, gives a brief history of the oyster industry in Yaquina Bay, reports on current conditions. Tables show salinity of Yaquina Bay for May-August, 1931 and 1931 spawning season. Recommends expanding production on State-owned beds.
Olympia oysters, “Ostrea conchaphila,” were once common along the west coast of North America. A popular delicacy, native oyster populations began to decline in the late 1800’s due to over‐harvest, degraded water quality, and habitat loss. Interest in re‐establishing the native oyster in a small Oregon estuary, Netarts Bay, culminated...
Oyster reefs provide an array of ecosystem services. Specifically, they provide structurally complex habitat for fish and invertebrate species such as the commercially important Dungeness crab, Metacarcinus magister. This ecosystem service, once provided by the native oyster Ostrea lurida, is now provided by the commercially cultured oyster Crassostrea gigas in...
The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...
