Molecular identification, phylogeny and geographic distribution of Brazilian mangrove oysters (Crassostrea)

Genetics and Molecular Biology, 2010
Oysters (Ostreidae) manifest a high degree of phenotypic plasticity, whereby morphology is of limited value for species identification and taxonomy. By using molecular data, the aim was to genetically characterize the species of Crassostrea occurring ...

Effect of carbonate chemistry alteration on the early embryonic development of the pacific pyster (Crassostrea gigas) [PDF]

, 2011
Ocean acidification, due to anthropogenic CO(2) absorption by the ocean, may have profound impacts on marine biota. Calcareous organisms are expected to be particularly sensitive due to the decreasing availability of carbonate ions driven by decreasing ...

The Crassostrea coquina bed in the Qeshm Geopark (Southern Iran): Paleontology, Paleoecology and Geotourism Potential

Geoconservation Research
The Crassostrea coquina bed on Qeshm Island is named for its high abundance of Crassostrea virginica fossils. Field surveys and photographic documentation from two key locations show that there are three lithostratigraphic units deposited in deltaic or ...

Shellfish face uncertain future in high CO2 world: influence of acidification on oyster larvae calcification and growth in estuaries. [PDF]

PLoS ONE, 2009
BACKGROUND: Human activities have increased atmospheric concentrations of carbon dioxide by 36% during the past 200 years. One third of all anthropogenic CO(2) has been absorbed by the oceans, reducing pH by about 0.1 of a unit and significantly altering

Nursery upweller type has minimal impact on subsequent grow-out of Eastern oysters (Crassostrea virginica)

Frontiers in Aquaculture, 2023
Demand for oysters in the premium half-shell market drives the need for research to optimize and improve oyster aquaculture production methods. After setting, oysters are typically maintained in nursery upwellers that provide nutrients and oxygen while ...

From blue to pink: resazurin as a high-throughput proxy for metabolic rate in oysters [PDF]

PeerJ
Metabolic rate assays are essential for assessing organismal stress and resilience, yet their use in aquaculture remains limited. We evaluate a whole-organism, resazurin-based metabolic assay for oysters (Crassostrea gigas and C.

Crassostrea virginica dredge efficiency in Texas estuaries [PDF]

Experimental Results, 2020
Abstract Quantifying and comparing stocks of oysters ( Crassostrea virginica ) within and among estuaries across the Gulf of Mexico is difficult because the sampling equipment used is either inconsistent among studies, or inefficient.
