Fig. 2 in Repeated stressors do not provoke habituation or accumulation of the stress response in the catfish Rhamdia quelen
Fig. 2. Plasma cortisol concentrations of R. quelen (Quoy & Gaimard) fingerlings exposed to sequential acute stressors. Comparison of responses to two similar stressors and a third different stressor in experiment "A" and comparison of responses to three sequential stressors of the same type in experiment "B." Data are expressed in terms of mean ± S.E.M. values. The different small letters above the histograms indicate statistical differences by ANOVA, followed by Tukey's range test. (n = 8-9).
Fig. 1 in Anesthetic activity of Brazilian native plants in silver catfish (Rhamdia quelen)
Fig. 1. Induction time and recovery of essential oils in silver catfish juveniles: a = Hesperozygis ringens; b = Ocotea acutifolia. Stages of induction were observed according to Schoettger & Julin (1967). Maximum observation time for induction and recovery was 30 min. Data are presented as mean±SEM (N = 5-6). Different letters indicate significant differences among concentrations for the same induction stage (P<0.05). Recovery time was omitted of Fig. 1b because it was higher than 30 min for most fish tested (see results).

Fig. 3. Blood glucose levels after anesthesia of silver catfish with essential oils: A = essential oil of Hesperozygis ringens; B = essential oil of Ocotea acutifolia; W = water control; EC = ethanol control. Data are presented as mean±SEM (N = 6). Different letters indicate significant differences among groups (P<0.05).

In experiment "A," Rhamdia quelen (Quoy & Gaimard) fingerlings were sequentially exposed to the same stressors twice and to a different stress the third time. In experiment "B," R. quelen fingerlings were sequentially exposed as the same stressors 3 times.
