Oysters provide a critical habitat, are a food resource for higher trophic levels and support important commercial fisheries throughout the world. Oyster reefs can improve water quality by removing phytoplankton. While sediment denitrification may be enhanced adjacent to oyster reefs, little is known about nitrification and denitrification associated with living oysters and their shells. We mea...

The effects of feeding dietary and defatted oyster meat on lipid metabolism were investigated in rats by comparing measurements with those of casein and soybean protein. In the first experiment, male rats were fed 0.1% and 1% cholesterol-supplemented diets containing casein, oyster or soybean protein under the same dietary level of protein (20%). The concentrations of serum and liver cholestero...

Title of Document: NAKED GOBIES (GOBIOSOMA BOSC) AS INDICATORS OF OYSTER REEF RESTORATION SUCCESS Terra M Lederhouse, M.S., 2009 Directed By: Dr. Kennedy T. Paynter, Director, Marine and Estuarine Environmental Sciences Naked gobies (Gobiosoma bosc) are the most abundant resident fish on oyster reefs in the Chesapeake Bay and serve as a critical trophic link between the benthic and pelagic comm...

Along the Indian coast, oysters were identified and studied since the beginning of the 20th century. One of the first records on the taxonomy of Indian oysters is by Hornell (1910) [2]. Since then a series of reports on the taxonomy of Indian oyster were made[1,3,4-9]. Originally the Indian oysters were referred to under the genus Ostrea but was later included under the genus Crassostrea. Anoth...

Dramatic declines in populations of the eastern oyster Crassostrea virginica are a symptom of degradation in many US Atlantic and Gulf of Mexico estuaries. We sampled 94 oyster reefs (88 constructed, 6 natural) within 11 no-harvest sanctuaries in estuaries of central and northern North Carolina, USA, to evaluate the success of oyster sanctuaries as a conservation tool. The sanctuaries have been...

Global loss of 85% of oyster reef ecosystems over the past 130 yr (Beck et al. 2011) has led to both growing recognition of the services once provided by healthy oyster reef ecosystems (Grabowski et al. 2012) and increasing interest in restoring these ecosystems. In Chesapeake Bay, USA, populations of the native oyster Crassostrea virginica have been reduced to <1% of historic levels through a ...

Oysters from the north-west coast of Canada contain high levels of cadmium, a toxic metal, in amounts that exceed food safety guidelines for international markets. A first required step to determine the sources of cadmium is to identify possible spatial and temporal trends in the accumulation of cadmium by the oyster. To meet this objective, rather than sample wild and cultured oysters of unkno...

Eastern oysters were ecologically and structurally dominant features of the Chesapeake Bay prior to European colonization. Four centuries of harvest pressure, habitat degradation, and, more recently, disease activity have affected extant oyster population demographics. We compared population demographics and age-at-shell length relationships for modern mesohaline James River oyster populations ...

One hundred and eighteen oyster samples collected from local markets and oyster farms in southern Thailand were examined for noroviruses (NoVs) and bacterial indicators of fecal contamination (fecal coliforms and Escherichia coli). Using a virus concentration procedure followed by RT-nested PCR, NoVs were detected in 38% of the samples. Oysters collected from oyster farms were found with NoVs a...
