3.2. PO activity in mature oysters stressed air exposure
Phenoloxidase activity declined significantly 48 h after oysterswere
exposed to air (p=0.046; Fig. 3; by 43%). Following this decline, PO
levels increased significantly (by 2.60 fold) relative to the controls after 96 h (p=0.023). Overall, PO activity increased significantly over
time in air-treated oysters (p=0.004), while PO activity in control oysters
did not differ significantly over time.
