Scientific names: Crassostrea gigas (Thunberg 1793), Ostreidae, Bivalvia Synonyms: Gryphaea angulata Lamarck 1819; Ostrea gigas Thunberg 1793; Ostrea laperousii Schrenk 1861; Ostrea talienwhanensis Crosse 1862. Note: The Portuguese oyster Crassostrea angulata is a name often used for this species. According to genetic studies it was shown that Crassostrea angulata is likely a strain of Crassost...
UNLABELLED In the summer of 2010, Vibrio parahaemolyticus caused an outbreak in Maryland linked to the consumption of oysters. Strains isolated from both stool and oyster samples were indistinguishable by pulsed-field gel electrophoresis (PFGE). However, the oysters contained other potentially pathogenic V. parahaemolyticus strains exhibiting different PFGE patterns. In order to assess the iden...
The relative contributions of the spring-neap tides, river discharge and vertical behavior to the dispersal of eastern oyster (Crassostrea virginica) larvae in Delaware Bay is investigated with a coupled circulation-individual-based larvae model. The coupled model simulates larval growth and behavior along particle trajectories using temperature and salinity conditions obtained from an implemen...
In Korea, oyster culture began in the early 1900’s. Commercial oyster culture using the hanging system started in the 1960’s, on the southern coast. After the 1960’s, production of cultured oysters has increased every year to the late 1980’s with the highest production recorded at 288,078 metric tons in 1987. This upward trend stagnated in the 1990’s and production dropped to 174,117 metric ton...
Mohar pearl oyster Pinctada radiata is the dominant economic species of pearl oyster in the Persian Gulf, particularly along the Iranian coastal waters. As pearling has been banned since 2006, stocks of pearl oysters has not been investigated during these years. For this purpose, conditions of natural habitats and stocks of Mohar pearl oyster in its old catch sites were surveyed in the present ...
Habitat suitability index (HSI) models provide spatially explicit information on the capacity of a given habitat to support a species of interest, and their prevalence has increased dramatically in recent years. Despite caution that the reliability of HSIs must be validated using independent, quantitative data, most HSIs intended to inform terrestrial and marine species management remain unvali...
The neuroendocrine-immune (NEI) regulatory network is a complex system, which plays an indispensable role in the immunity of the host. In the present study, the bioinformatical analysis of the transcriptomic data from oyster Crassostrea gigas and further biological validation revealed that oyster TNF (CgTNF-1 CGI_10018786) could activate the transcription factors NF-κB and HSF (heat shock trans...
Pesticides are frequently detected in estuaries among the pollutants found in estuarine and coastal areas and may have major ecological consequences. They could endanger organism growth, reproduction, or survival. In the context of high-mortality outbreaks affecting Pacific oysters, Crassostrea gigas, in France since 2008, it appears of importance to determine the putative effects of pesticides...
The protozoan parasite Marteilia refringens has been partly responsible for the severe decrease in the production of the European flat oyster Ostrea edulis Linnaeus in France since the 1970s. The calanoid copepod Paracartia grani Sars was recently found to be a host for M. refringens in French shallow-water oyster ponds ('claires'). This study reconsidered M. refringens transmission dynamics in...
Expectations of ecological and fisheries benefits of habitat restoration are commonly used to justify its high financial cost; however, few empirical studies that rigorously test these expectations exist. Here, we describe the results of a study designed to quantify the effects of restoring oyster reefs in marsh tidal creeks on the mobile macrofauna. We used a before/after control/impact (BACI)...
