DNA fingerprinting of pearls to determine their origins. [PDF]
PLoS ONE, 2013 We report the first successful extraction of oyster DNA from a pearl and use it to identify the source oyster species for the three major pearl-producing oyster species Pinctada margaritifera, P. maxima and P. radiata. Both mitochondrial and nuclear gene

Different food particle sources in the pearl oyster Pinctada margaritifera and its epibionts
Aquaculture Reports, 2021 Suspended bivalve culture (e.g. longlines) transfers benthic biomass - including bivalves and various epibionts - toward the water column, creating strong trophic interactions with the planktonic compartment.

Colour or no colour in the juvenile shell of the black lip pearl oyster, Pinctada margaritifera? [PDF]
Aquatic Living Resources, 2012 Pinctada margaritifera mollusc is cultivated in French Polynesia for the production of black pearls. For this study, the colour of juvenile samples (48 days old) was investigated in the visible range spectra (430–700 nm) using spectrophotometry. A first measurement was done with the soft parts still inside the shell (entire animal).

Response of the pearl oyster Pinctada margaritifera to cadmium and chromium: Identification of molecular biomarkers [PDF]
Marine Pollution Bulletin, 2017 This study was designed to identify in the pearl oyster Pinctada margaritifera, used as a bio-accumulator, molecular biomarkers for the presence of heavy metals in the lagoon environment. Pearl oysters were exposed to 2 concentrations (1 and 10μgL-1) of cadmium (Cd) and chromium (Cr) compared to a control.
