Pinctada margaritifera responses to temperature and pH: Acclimation capabilities and physiological limits [PDF]

open access: yesEstuarine, Coastal and Shelf Science, 2016
The pearl culture is one of the most lucrative aquacultures worldwide. In many South Pacific areas, it depends on the exploitation of the pearl oyster Pinctada margaritifera and relies entirely on the environmental conditions encountered in the lagoon.

Substantial gene expression shifts during larval transitions in the pearl oyster Pinctada margaritifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 2, Page 76-84, March 2024.
Larval transition is associated with large shifts in gene expression in Pinctada margaritifera. Abstract Early development stages in marine bivalve are critical periods where larvae transition from pelagic free‐life to sessile mature individuals. The successive metamorphosis requires the expression of key genes, the functions of which might be under ...

Genetic Effects of Pearl Culture Practices and Recruitment of the Black-Lipped Pearl Oyster (Pinctada margaritifera) in French Polynesia

open access: yes, 2011
French Polynesia relies solely on the collection of wild Pinctada margaritifera spat for pearl oyster culture. This was developed to help protect the wild populations from overexploitation, but it is feared that massive spat collection could lead to ...
