Figure 6. Locomotor behaviour of zebrafish larvae reared under different temperature groups.

Swimming activity (number of events recorded every 10 seconds) was observed in 3 and 10 days post fertilization (dpf) larvae. Data is expressed as mean±SEM. Different lowercase (3 dpf) and uppercase (10 dpf) letters indicate statistical differences among temperature groups (Student’s t-test and ANOVA, P<0.05, N = 30 per temperature group). Abbreviations as in Figure 1.
