From: Atlantic cod actively avoid CO2 and predator odour, even after long-term CO2 exposure
CO 2 avoidance in Atlantic cod after long-term exposure to control water or high pCO 2 water. Mean time (%) that juvenile Gadus morhua spent in the control water (550 μatm CO2) when presented with the choice of control water or high pCO2 water (1170 μatm CO2); ncontrol = 19 and nCO2 = 12. Fish from both acclimation groups were tested: the control fish and the long-term CO2-exposed fish. Both treatment groups displayed equally strong avoidance (p = 0.0001). The data represent the mean ± SEM.
