Behavioural entrainment by periodic food availability of gr^+/+ and gr^−/− zebrafish juvenile. (A) Larvae were reared under LL from 15 to 35 dpf and fed once a day at a midday time for 20 days. After then larvae were starved for 84 h and the locomotor activity were recorded. (B) Mean waveform of locomotor activity under LL and starvation for 84 h (n = 45/genotype). Vertical dotted lines denote when the feeding would normally have occurred according to the previous regular feeding regime.
