heavy metal pollution in aquatic ecosystems has become one of the global issues. mollusks such as clams can be used as bioindicators and biomonitors of heavy metal pollution in these ecosystems. in fact, mussels and oysters have been widely used for this purpose. in this study, the concentrations of cadmium were measured in soft tissues of rock oysters )saccostrea cucullata( collected from two ...

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 paramyxean protozoan, Marteilia sydneyi, is the etiological agent of QX disease in Sydney rock oysters (Saccostrea glomerata). QX disease affects the farming of oysters in Queensland and on five rivers in New South Wales (NSW), Australia. Disease outbreaks occur during summer months (January to April) and are associated with high mortality rates (up to 98%), which limit the growing out peri...

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...

The European flat oyster, Ostrea edulis, is an important ecosystem engineer that has been progressively disappearing from coasts over the last century mainly due to overexploitation, habitat degradation and disease. It now subject of many conservation restoration programs throughout Europe, including Flat Oyster REcoVERy (FOREVER) project in France. Protecting managing remaining populations bec...
