Seasonal variation of pollution biomarkers to assess the impact on health status of juvenile Pacific oysters Crassostrea gigas exposed in situ
International audience Background, aim, and scope In this study, a suite of sublethal stress biomarkers were analysed in juveniles of the sentinel species, the Pacific oyster Crassostrea gigas, with a view to using them as pollution monitoring tools. The aim of this work was (1) to study baseline se...
