| Salmo salar | 36 ± 3 | 18 | 151 ± 41 | Barnes et al. (2011)a |
| 45 ± 4 | 22 | |||

| 28 | 35 | 295 ± 49 | ||
| Anguilla anguilla | 16 | 25 | (yellow phase) | Cruz-Neto and Steffensen (1997)b |
| Oreochromis niloticus | 11 ± 3 | 25 | 301 ± 46 | Fernandes and Rantin (1989)b |

aValues of [O2]crit were converted to percentage saturation from milligrams per litre (100% saturation = 9.4 mg l−1 at 18°C and 8.7 mg l−1 at 22°C).
bValues of [O2]crit were converted to percentage saturation from millimetres of mercury (100% saturation = 159 mmHg).
