Effect of the predator on cortisol level of zebrafish. Experimental design and whole-body cortisol response of the target zebrafish. Mean values (±S.E.M.) compared by Kruskal-Wallis complemented by a Dunn's Multiple Comparisons Test. Means with at least a same letter above mean are not statistically different from each other (P indicated in the graph). Numbers of repetitions obtained for each treatment (T1 to T6) are inside each column. The fish drawings in the graphics were drawn by LB.
