By measuring the fluorescence spectra of pearls from various species of mother oysters, a distinction has already become possible as to whether the pearls are from Pinctada fucata, Pinctada maxima, Pteria penguin or Pinctada margaritifera. In this study, the fluorescence of pearls from freshwater bivalves was measured. The results have made it possible to distinguish freshwater pearls from the ...

background: persian gulf is a semi-closed environment which is affected by pollution ‎from heavy metals. entrance of heavy metals to the water column and binding to ‎sediment particles can affect the benthic organisms that can accumulate these ‎materials in their body. noticing this ability, mussels are considered as bio-monitoring ‎agents.‎ methods: the pearl oyster, pinctada radiate, and sedi...

Seasonal variations of three heavy metals (Pb,Cd, Ni) in Pinctada radiata have been conducted in Hendorabi and lavan Island from March 2011 to march 2013, edible oysters are best pollution indicator organism in aquatic environment. The soft tissue of Pinctada radiata and sediment was analyzed to detect some potentially toxic metals as Pb, Cd, Ni with a flame AAS and statistical analyses were pe...

Pearl oyster Pinctada fucata is widely cultured to produce seawater pearl in South China, and the quality of pearl is significantly affected by its shell color. Thus the Pearl Oyster Selective Breeding Program (POSBP) was carried out for the shell color and growth traits. The black (B), gold (G), red (R) and white (W) shell strains with fast growth trait were achieved after five successive gene...

This study examines the seasonal changes of marine birnavirus (MABV) in seawater and the Japanese pearl oyster Pinctada fucata reared at different depths (2 and 15 m). Oysters and seawater were collected in 1998, and a 2-step PCR was carried out to detect MABV. Virus isolation was performed on the PCR-positive samples in the oyster. The detection rate of the MABV genome in the oyster was low du...
