Toxicity and histopathological effects of toxic dinoflagellate, Alexandrium catenella exudates on larvae of blue mussel, Mytilus galloprovincialis, and Pacific oyster, Crassostrea gigas

Jurnal Ilmiah Perikanan dan Kelautan, 2020
Highlight • Toxicity and pathological effects of A. catenella were investigated on shellfish larvae • Unfiltered exudates of A. catenella caused significant mortality of blue mussel larvae • Application of 0.22 mm filtration on A.

Growth and Reproduction of the Pacific Oyster Crassostrea gigas Cultured on Tidal Flat in Hebei Spirit Oil Spill Area on the West Coast of Korea Four Years After the Accident

Frontiers in Marine Science, 2022
The Hebei Spirit oil spill (HSOS) accident in December 2007 on the west coast of Korea devastated the intertidal oyster farms along the Taean coast, resulting in the shut-down of the farming for three years.

On the edge: assessing fish habitat use across the boundary between Pacific oyster aquaculture and eelgrass in Willapa Bay, Washington, USA

Aquaculture Environment Interactions, 2020
Estuaries are subject to diverse anthropogenic stressors, such as shellfish aquaculture, which involve extensive use of estuarine tidelands. Pacific oyster Crassostrea gigas aquaculture is a century-old practice in US West Coast estuaries that ...

Differential Mortality and High Viral Load in Naive Pacific Oyster Families Exposed to OsHV-1 Suggests Tolerance Rather than Resistance to Infection

Pathogens, 2020
Pacific oysters, Crassostrea gigas, are one of the most productive aquaculture species in the world. However, they are threatened by the spread of Ostreid herpesvirus-1 (OsHV-1) and its microvariants (collectively “µvars”), which cause mass mortalities ...

Biochemical Polymorphism in the Pacific Oyster-III

NIPPON SUISAN GAKKAISHI, 1978
Genetic variations have previously been described in the myogen, est erases, tetrazolium oxidase, and leucine arninopeptidases in the Pacific oyster, Crassostrea gigas. Some 900 specimens (35 lots) of the Pacific oyster, sampled from the wild populations off the Pacific and the Japan Sea coasts of Hokkaido, and off Iwate and Akita Prefectures, as well ...

Influence of environment on the pathogenesis of Ostreid herpesvirus-1 (OsHV-1) infections in Pacific oysters (Crassostrea gigas) through differential microbiome responses

Heliyon, 2019
The oyster microbiome is thought to contribute to the pathogenesis of mass mortality disease in Pacific oysters, associated with OsHV-1. As filter-feeders, oysters host a microbiota that can be influenced by the estuarine environment.

Functional Analysis on Shelk2 of Pacific Oyster [PDF]

, 2018
Shelk2, a novel shell matrix protein from the Pacific oyster, Crassostrea gigas, is reported to be involved in shell biosynthesis of the prismatic layer. Results of RNAi experiment on shelk2 showed that Shelk2 has a key role in shell regeneration. When dsRNA of shelk2 was injected into the adductor muscle of Pacific oyster, the prismatic layer did not ...

Field tests of trophic interactions between non-native European green crabs (Carcinus maenas) and non-native clams along an estuarine gradient [PDF]

Aquatic Invasions
Estuaries are highly invaded ecosystems exhibiting many novel species interactions. This project addressed how predation from native and non-native crabs influences density of non-native clams along an estuarine gradient in Willapa Bay (Washington, USA).

Wild populations of Pacific oysters (Magallana gigas) emerge during the blob heatwave in south Puget Sound, Washington USA

Frontiers in Marine Science
Marine heatwaves have altered ecosystems globally, including changing community composition and facilitating the spread of invasive species. In south Puget Sound, Washington (USA), non-native Pacific oysters (Magallana gigas) have been farmed extensively
