Fig. 1. The frequency of ABR in T. microlepis exposed to normoxia and hypoxia for 14 days. The frequency of ABR in the hypoxic group was significantly higher than that in the control group at days 1, 2, 4, 7, and 14 (asterisk indicates a significant difference between hypoxia and normoxia, t test, P <0.05). The frequency in the hypoxic groups increased to its highest level at day 1 and then gradually decreased to a stable level until the end of the 14-d experiment (Tukey's test, P <0.05).
