Spawning-dependent stress response to food deprivation in Pacific oyster, Crassostrea gigas

Transcriptomic response of the Pacific oyster Crassostrea gigas to hypoxia.

Marine intertidal organisms commonly face hypoxic stress during low tide emersion; moreover, eutrophic conditions and sediment nearness could lead to hypoxic phenomena; it is indeed important to understand the molecular processes involved in the response to hypoxia. In this study the molecular response of the Pacific oyster Crassostrea gigas to prolonged hypoxia (2mg O(2) L(-1) for 20d) was inv...

Synergistic impacts of heat shock and spawning on the physiology and immune health of Crassostrea gigas: an explanation for summer mortality in Pacific oysters.

Mass mortality is often observed in cultured oysters during the period following spawning in the summer season. To examine the underlying causes leading to this phenomenon, thermotolerance of the Pacific oyster Crassostrea gigas was assessed using pre- and postspawning oysters that were sequentially treated with sublethal (37 degrees C) and lethal heat shocks (44 degrees C). The effects were ex...

The Effects of 4-nonylphenol on the Immune Response of the Pacific Oyster, Crassostrea Gigas, following Bacterial Infection (vibrio Campbellii)

Physiological recovery from prolonged ‘starvation’ in larvae of the Pacific oyster Crassostrea gigas

Previous studies of energy metabolism in larvae have described a developmental ‘‘point of no return’’ (PNR), a time by which larvae of planktotrophic marine species must feed in order to survive and grow. This study investigated the effects of long-term food deprivation on developing larvae of the oyster Crassostrea gigas with the goal of providing a biochemical and metabolic description of lar...

The estimation of Dynamic Energy Budget (DEB) parameters for Crassostrea gigas larvae Rico-Villa, Benjamin and Pouvreau, Stéphane Département de Physiologie Fonctionnelle des Organismes Marins, Station IFREMER

The major commercial marine bivalve in French aquaculture is the Pacific oyster, Crassostrea gigas. Traditionally, bivalve culture relies on juvenile collection from the natural environment but due to the high year-to-year variation in spatfall recruitment the spat production in hatcheries is increasing recently. In this context, a better understanding of the biology of C. gigas larvae is requi...
