- •
Deepwater Horizon oil spill coincided with oyster spawning and recruitment season.
- •
Different Crassostrea virginica larval stages were exposed to oil and/or Corexit for 72–96 h.
- •
HEWAF, CEWAF and Corexit reduced larval growth, settlement success and survival.
- •
Toxic effects were observed at environmentally relevant concentrations of tPAH50.
- •
Sublethal doses of PAH may impact oyster populations and the whole ecosystem.
