Fig. 2. Chronological changes of the cardiorespiratory status of 6-, 10- and 15°C-acclimated common carp exposed to severe hypoxia. Note the different time scales among temperature groups. Significant differences (P
0.05) from time zero are indicated by the solid line above the traces. Circled data points are designated as the normoxic control, hypoxic minimum, and hypoxic maximum values and correspond with those given in Table 1. Values are means ± S.E.M.; N=8 (6°C), 15 (10°C) and 8 (15°C) unless otherwise indicated (numbers above points).
