BACKGROUND Oyster norovirus outbreaks often pose high risks to human health. However, little is known about environmental factors controlling the outbreaks, and little can be done to prevent the outbreaks because they are generally considered to be unpredictable. OBJECTIVE We sought to develop a mathematical model for predicting risks of oyster norovirus outbreaks using environmental predicto...

This study was conducted to evaluate the calcium (Ca) absorption efficacy of king oyster mushroom (Pleurotus eryngii) grown on sawdust medium supplemented with Ca-sources, including oyster shell powder, and to determine the efficacy of oyster shell powder as a calcium supplement on growth, yield, spawn run and primordial formation of P. eryngii. Optimum calcination of oyster shell powder was ac...

the effect of microbial load on the condition index of the edible oyster, saccostrea cucullata were analysed on monthly basis during 2010 and 2011 from the three different stations (namkhana, frasergaunge and sajnekhali) of indian sundarbans. the results showed significant variation with respect to microbial load between stations and seasons, which is reflected in the tissue of edible oyster. s...

Background There are a variety of marine worm species that commonly inhabit the benthic sediment of oyster growing areas. Because of the oysters proximity to the substrate, benthic worms may often be found in the external crevices of oyster shells. As well, the worms may inhabitant the holes in oyster shells created by the boring sponge Cliona sp. which bore holes when feeding on the oyster she...

Oyster extract was prepared by hydrolysis of oyster protein with proteases, Aloase (a protease from Bacillus subtilis), and Pancitase (a protease from Aspergillus oryzae). Rats were fed a diet containing 20% casein (the control diet) or 15% casein and 5% oyster extract (the oyster extract diet) as the protein source. The oyster extract diet exerted a significant reduction in serum cholesterol a...

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...
