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.

Mantle histology, histochemistry and ultrastructure of the pearl oysterPinctada margaritifera(L.) [PDF]

Aquatic Living Resources, 1992
The edge and isthmus of the mantle of Pinctada margaritifera (Mollusc, Bivalvia) were studied using light and electron microscopy from a morphological and histochemical point of view. Six areas with several subareas were differentiated in the mantle edge.

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples

Advanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Screening Relaxants for Efficacy and Effects on Growth for Greenlip Abalone, Haliotis laevigata Donovan

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...

Genetic Relatedness and Parentage Analysis as a Framework to Enhance Local Conservation Strategies for Marine Species

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We investigated the genetic structure and parentage relationships within a nearly complete population of Atrina vexillum in Bora‐Bora. Using 30 microsatellite markers and spatially explicit sampling, we found strong family clustering despite the absence of overall population structure.

Morphometric measurements of pearl shell shells Pinctada margaritifera for aquarium cultivation

Jurnal Moluska Indonesia, 2022
The pearl oyster Pinctada margaritifera or the black-lipped oyster is one of the important species used in the pearl industry. The availability of natural pearl oyster seeds is limited, while exploitation is increasing. The purpose of this field work practice is to measure and observe the morphometric comparisons of Arakan, Mantehage Bango and Talengen

Microbiome of the Boring Giant Clam Provides Insights Into Holobiont Resilience Under Coral Reef Environmental Stress

Environmental Microbiology, Volume 27, Issue 8, August 2025.
The microbiome of the boring giant clam, Tridacna crocea, varies among tissues, with Endozoicomonas dominating most tissues and putative carotenoid‐producing bacteria (Rubritalea, Muricauda) enriched in the outer mantle. Using dark‐induced bleaching, we examined the impact of symbiont loss on bacterial communities and found that the overall bacterial ...
