Spontaneous swimming behavior of larval zebrafish at 5 dpf, comparing following hypoxia, to normoxia
| Treatment | Swimming distance (mm) | Velocity (mm/s) | Rotation frequency (no/10 min) | |||
|---|---|---|---|---|---|---|
| Dark (4×) | Light (3×) | Dark (4×) | Light (3×) | Dark (4×) | Light (3×) | |
| Normoxia, n = 30, 21% pO2 | 616.6 ± 48.3 | 385.3 ± 38.3 | 1.4 ± 0.1 | 0.9 ± 0.1 | 60.4 ± 3.2 | 43.2 ± 3.4 |
| Hypoxia 24–48 hpf, n = 30, 1% pO2 | 399.5 ± 36.0 | 197.2 ± 33.2 | 0.9 ± 0.1 | 0.4 ± 0.1 | 50.8 ± 4.6 | 31.6 ± 5.1 |
| Hypoxia 48–72 hpf, n = 25, 3% pO2 | 312.5 ± 28.8 | 102.9 ± 18.8 | 0.7 ± 0.1 | 0.2 ± 0.1 | 43.3 ± 4.4 | 18.3 ± 2.6 |
| Hypoxia 72–96 hpf, n = 30, 5% pO2 | 391.0 ± 31.6 | 190.7 ± 28.7 | 0.9 ± 0.1 | 0.4 ± 0.1 | 50.5 ± 34.1 | 27.9 ± 3.3 |
Behavioral paradigm used alternating light and dark exposures (see Materials and Methods for full description).
