Fig. 7. Oxygen consumption of developing zebrafish larvae between 2 d.p.f. and 15 d.p.f., Values for animals between 1 and 9 d.p.f. were measured in a twin flow respirometer. Values are means ± S.E.M. from seven experiments. Within each experiment 10–15 eggs were pooled. Values for 11, 13 and 15 d.p.f. were taken from Bagatto et al. (2001), originally measured at 25°C. Data were recalculated to 28°C using a Q₁₀ of 3.2, as determined for 10 d.p.f. animals for the temperatures between 25°C and 28°C (Barrionuevo and Burggren, 1999). ^*Significant differences relative to the previous day (P<0.05).
