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.

Anaesthetic induced relaxation of the winged pearl oyster, Pteria penguin, varies with oyster size and anaesthetic concentration

Aquaculture Reports, 2022
Stress and mortality of pearl oysters during nucleus implanting for round pearl and mabé pearl production can be reduced using appropriate anaesthetics that allow improved access to nucleus implanting sites.

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.

Responses of Pearl Oysters to Marine Heatwaves as Indicated by HSP70

Frontiers in Marine Science, 2022
Marine heatwaves (MHWs) can severely affect bivalves and ecosystems they support. Heat shock proteins (HSPs) are a group of molecular chaperones playing a critical role in the cellular protection and thermo tolerance and thereby constraining ...

Expression pattern of genes involved in biomineralization in black and orange mantle tissues of pearl oyster, Pinctada persica

Frontiers in Marine Science, 2023
A few species of mollusks display color variation in their soft tissues. In pearl oysters, the color polymorphism in mantle tissue is associated with the color and radiance of shell and pearl. The study of biomineralization related genes in mantle tissue

Development of SSR marker by RNA-seq and its application in genotyping pearl sac in pearl oyster Pinctada fucata martensii

Electronic Journal of Biotechnology, 2017
Background: Pearl oyster Pinctada fucata martensii is cultured for producing round nucleated pearls. Pearl production involves a surgical operation where a mantle tissue graft from a donor oyster and a round nucleus are implanted in the gonad of a host ...
