Census of potential predators and competitors of sandfish, Holothuria scabra, juveniles during floating hapa ocean nursery culture

open access: yesAquaculture, Fish and Fisheries, Volume 3, Issue 3, Page 316-328, June 2023., 2023
This study reports for the first‐time potential predators and competitors that recruited and migrated to floating hapa nets during ocean nursery culture of sandfish juveniles reared in the Philippines. Results indicate that the presence of potential predators and competitors within the floating hapas negatively affected growth performance and survival ...

Unusual conservation of mitochondrial gene order in Crassostrea oysters: evidence for recent speciation in Asia [PDF]

open access: yes, 2010
Background Oysters are morphologically plastic and hence difficult subjects for taxonomic and evolutionary studies. It is long been suspected, based on the extraordinary species diversity observed, that Asia Pacific is the epicenter of oyster

Whole genome sequencing of Crassostrea ariakensis (Mollusca: Ostreidae) and C. hongkongensis expands understandings of stress resistance in sessile oysters.

open access: yesGenomics, 2023
To understand the environmental adaptations among sessile bivalves lacking adaptive immunity, a series of analyses were conducted, with special emphasis on the widely distributed C. ariakensis.

Molecular phylogenetics and systematics of the bivalve family Ostreidae based on rRNA sequence-structure models and multilocus species tree.

open access: yesPLoS ONE, 2014
The bivalve family Ostreidae has a worldwide distribution and includes species of high economic importance. Phylogenetics and systematic of oysters based on morphology have proved difficult because of their high phenotypic plasticity.
