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.

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.

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 ...

Growth and Survival of Black-lip Pearl Oyster Pinctada margaritifera (Linnaeus, 1758) in Bamboo and Metal-framed Pocket Net Baskets Subjected to Cleaning and Without Cleaning Conditions

The Philippine Journal of Fisheries, 2022
The farming of black-lip pearl oyster Pinctada margaritifera (Linnaeus, 1758) has been a viable industry for small and large-scale farmers in the South Pacific, but not in the Philippines, where it is monopolized by large-scale farms primarily based on ...

Heat Stress Response in Ruditapes Decussatus: Transcriptional Regulation of Key Pathways and Novel SNPs in Antioxidant Genes

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Climate change is known to affect all levels of biology, setting at risk ecological balance. Among other organisms' groups, aquatic inhabitants, and particularly bivalves, are expected to be influenced to a greater extent owing to their inability to move to more mild temperatures.

Fish Predation in Bivalve Aquaculture: Impacts and Potential Mitigation Strategies

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Fish predation poses a significant challenge to bivalve aquaculture throughout the global range of production. However, the issue remains poorly understood, preventing the advance of effective interventions. Fish predation, especially on mussels in longline culture, can be severe and, in some instances, lead to crop losses of up to 100%, which

Aggregation Behaviour as an Adaptive Reproductive Strategy in a Marine Ecosystem Engineer

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Mussels play a key role in coastal ecosystems by forming dense aggregations that provide habitats and enhance biodiversity. Here, we showed that the mussel aggregation rate varies seasonally according to their reproductive cycle, increasing during gamete maturation and declining postspawning, supporting a reproductive function for this behaviour.

Trophic relationships between the farmed pearl oyster Pinctada margaritifera and its epibionts revealed by stable isotopes and feeding experiments

Aquaculture Environment Interactions, 2016
Bivalve cultures support a host of epibionts, mainly suspension feeders, which can compete for food resources with the cultivated bivalves. However, the magnitude of interspecific competition for food in bivalve aquaculture settings remains inconclusive,

A micro‐geoarchaeological investigation of a cultivation pit (maite) on Teti'aroa atoll, Central‐East Polynesia

Archaeology in Oceania, Volume 60, Issue 1, Page 17-41, April 2025.
ABSTRACT Cultivation pits represented the principal form of horticultural features developed by past atoll communities in Central‐East Polynesia (CEP), and they are still utilised on some atolls in Oceania. The majority of information about the use of cultivation pits in CEP derives from ethnographic and preliminary archaeological investigations.

Influence of preoperative food and temperature conditions on pearl biogenesis in Pinctada margaritifera [PDF]

Aquaculture, 2017
Trophic conditions and water temperature strongly influence bivalve physiological processes and metabolism. In black-lip pearl oyster Pinctada margaritifera, these parameters have been shown to affect shell biomineralization. The present study investigated the effect of preoperative food level (i.e., microalgal concentration) and temperature on pearl ...
