The plate collector, a new option for Pinctada margaritifera spat collection in French Polynesia
Aquaculture Reports, 2022 The aquaculture industry can constitute an important source of waste in the environment. In atoll lagoons of French Polynesia, among the materials used by pearl farmers, shade-mesh collectors can release toxic substances and are responsible of ...

Sustainability and traceability in marine cultured pearl production [PDF]
, 2014 For centuries, wild pearl oysters and mussels were fished in the quest for natural pearls and shell material. This eventually led to the drastic overexploitation of oyster stocks in many areas of the globe.

Histopathology of oedema in pearl oysters Pinctada maxima [PDF]
Diseases of Aquatic Organisms, 2010 In October 2006, severe mortalities (80 to 100%) were reported in pearl oyster Pinctada maxima production farms from Exmouth Gulf, Western Australia. Only P. maxima were affected; other bivalves including black pearl oysters P. margaratifera remained healthy. Initial investigations indicated that the mortality was due to an infectious process, although

A homeodomain transcription factor gene, PfMSX, activates expression of Pif gene in the pearl oyster Pinctada fucata. [PDF]
PLoS ONE, 2014 We reported pearl oyster Pinctada fucata cDNA and genomic characterization of a new homeobox-containing protein, PfMSX. The PfMSX gene encodes a transcription factor that was localized to the nucleus.

Physical Responses of Pinctada fucata to Salinity Stress [PDF]
Frontiers in Marine Science, 2022 This study was conducted to understand the changes of physiological and biochemical indexes of black and red shell Pinctada fucata under acute high and low salt stress. In this study, the salinity of 35‰ was used as the control, while the salinities of 20 and 50% salinity were used as the low and high salt treatment groups, respectively.

Anisotropy of Mechanical Properties of Pinctada margaritifera Mollusk Shell [PDF]
Nanomaterials, 2020 The mechanical properties such as compressive strength and nanohardness were investigated for Pinctada margaritifera mollusk shells. The compressive strength was evaluated through a uniaxial static compression test performed along the load directions parallel and perpendicular to the shell axis, respectively, while the hardness and Young modulus were ...

Exploring HSP90 as a Biomarker for Marine Heatwaves in Pinctada maxima
Frontiers in Marine Science, 2022 Many species, particularly marine organisms, are becoming more vulnerable to marine heatwaves due to climate change. Marine species anticipate perishing during marine heatwaves, but there is a growing interest in learning why some can resist.
