From: Zebrafish automatic monitoring system for conditioning and behavioral analysis
Zebrafish simple appetite conditioning responses using one stimulus: Red LED light. (A) Number of fish that were in the eating behavior before the light was turned on, (B) while the light was on, (C) during the feeding period and (D) after the stimulus is turned off. The horizontal lines of each group denote the mean ± SD and the asterisks on the brackets indicate statistical difference in comparison to the frequency of fish between the attempt and the control group by Mann–Whitney U-test (*p < 0.05; * *p < 0.001, ***p < 0.0001).
