OsHV-1 and notifiable protozoa in healthy Crassostrea corteziensis cultured in two distant areas of the Gulf of California

Infectious diseases have been a major limiting factor for large scale production of oyster farming. Several factors have contributed to the emergence and spread of infectious diseases in all cultivation sites around the world. Therefore, the prevention and control of diseases has become a priority for the sustainability of global aquaculture. Crassostrea corteziensis is a … Continue reading OsHV-1 and notifiable protozoa in healthy Crassostrea corteziensis cultured in two distant areas of the Gulf of California

Oysters under threat from deadly herpes virus that is spreading around the world

THE world could soon be facing an oyster shortage as a deadly herpes virus is threatening to devastate oyster populations. The virus known as Ostreid herpesvirus 1 (OsHV-1), is impacting Pacific oysters, which is the most popular species to eat due to their large size and experts are worried it could continue to spread around … Continue reading Oysters under threat from deadly herpes virus that is spreading around the world

Metabolomic applications in marine mollusc development and aquaculture

Metabolomics is a rapidly emerging discipline within functional genomics to better understand biochemical phenotypes across a range of biological systems. The approach has many demonstrated applications in aquatic biology, but has not yet been applied to study early lifestages of marine molluscs. This Thesis evaluates metabolomics as an approach to characterise early lifestage phenotypes of … Continue reading Metabolomic applications in marine mollusc development and aquaculture

Mortality in Crassostrea gigas oysters in Ireland during 2012

OsHV-1 mu Var-related mortality is well described in several countries, including France. In Ireland, however, clear patterns in relation to the incidence and impact of this virus have been difficult to identify, at least in part because seawater temperatures rarely exceed 16 degrees C, a recognised threshold for OsHV-1 mu Var-related mortality, for prolonged periods. … Continue reading Mortality in Crassostrea gigas oysters in Ireland during 2012

Future CRC-P : advanced understanding of POMS to guide farm management decisions in Tasmania (project)

Pacific Oyster Mortality Syndrome (POMS) caused by the OsHV-1 virus was first detected in Tasmania in January 2016 with mass mortalities of cultured Pacific oysters on farms in several major oyster growing areas, including Pittwater, Pipeclay Lagoon, Blackman Bay and Little Swanport. Prior to this outbreak, Tasmanian oyster farms produced around four million dozen oysters … Continue reading Future CRC-P : advanced understanding of POMS to guide farm management decisions in Tasmania (project)

Oysters can get herpes, and it’s killing them. A deadly virus threatens to decimate oyster populations around the world

Oysters, a delicacy eaten on most coastlines of the world, are a multi-billion-dollar industry. They also are intriguing to study from a health perspective. Oysters feed by filtering tiny plankton from the surrounding water, processing up to 50 gallons per oyster daily. In doing so, they improve water quality and make their ecosystems healthier. But the water … Continue reading Oysters can get herpes, and it’s killing them. A deadly virus threatens to decimate oyster populations around the world

Molecular characterization of Pacific oyster (Crassostrea gigas) IRAK4 gene and its role in MyD88-dependent pathway

Interleukin-1 receptor-associated kinases (IRAKs) play important roles in MyD88-dependent TLR signaling, the crucial innate immune pathway in molluscs. In this study, we examined the full-length IRAK4 genetic sequence in the Pacific oyster (Crassostrea gigas) by molecular cloning. Phylogenetic analysis revealed that CgIRAK4 is most closely related to Mytilus edulis, and forms a clade with other molluscs. CgIRAK4 transcripts are widely … Continue reading Molecular characterization of Pacific oyster (Crassostrea gigas) IRAK4 gene and its role in MyD88-dependent pathway
