Partial inhibition of hemocyte agglutination by Lathyrus odoratus lectin in Crassotrea virginica infected with Perkinsus marinus

Memorias do Instituto Oswaldo Cruz, 1995
Quantitative determinations of agglutination of hemocytes from oysters, Crassostrea virginica, by the Lathyrus odoratus lectin at five concentrations revealed that clumping of hemocytes from oysters infected with Perkinsus marinus is partially inhibited.

Identificación del ostión americano Crassostrea virginica (Mollusca: Bivalvia: Ostreidae) como recurso natural en las Antillas Mayores: Cuba

Revista Mexicana de Biodiversidad, 2016
El ostión de Mangle Crassostrea rhizophorae (Guilding, 1828) ha sido considerado la única especie de ostión nativo que se comercializa en Cuba. Sin embargo, se han encontrando agregaciones de «ostión de fondo» en las cuencas de los ríos Cuyaguateje y ...

CO2-induced low pH in an eastern oyster (Crassostrea virginica) hatchery positively affects reproductive development and larval survival but negatively affects larval shape and size, with no intergenerational linkages

, 2020
In North America, studies regarding effects of CO2-induced low pH in bivalve aquaculture are largely restricted to the US Pacific coast. Studies on species from the northwest Atlantic are lacking.

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 ...

Low concentrations and low spatial variability of marine microplastics in oysters (Crassostrea virginica) in a rural Georgia estuary.

Marine Pollution Bulletin, 2019
Microplastics are an emerging concern for the health of marine ecosystems. In the southeastern US, the filter-feeding Eastern oyster, Crassostrea virginica, is susceptible to microplastic ingestion.

Multiple-locus heterozygosity, physiology and growth at two different stages in the life cycle of the Chilean oyster Ostrea chilensis [PDF]

, 1996
A random sample of 150 individuals of a laboratory-produced cohort of Ostrea chilensis Philippi, 1845 was taken at 10 and 36 mo of age to estimate physiological variables and individual heterozygosity using 4 loci (Lap, Pgi, Pgm and Ca).

Effects of anthropogenic sounds on the behavior and physiology of the Eastern oyster (Crassostrea virginica)

Frontiers in Marine Science, 2023
IntroductionNoise pollution is a major stressor in the marine environment; however, responses of economically and ecologically important invertebrates, such as oysters, are largely unknown.MethodsUnder laboratory conditions, we measured acute behavioral ...
