Figure 3. Experiment II.

(A) Schematic representation of the behavioural treatments. From left to right: Alone_AS–alone focal fish (red filling) administered with AS; SB (O)_AS–focal fish (orange filling) administered with AS and exposed to shoal water of 8 conspecifics; SB (V)_AS–focal fish (blue filling) administered with AS and exposed to a shoal of 8 conspecifics and SB (O + V)_AS–focal fish (green filling) administered with AS and exposed simultaneously to shoal water and a shoal of 8 conspecifics. Red drops represent AS administration. (B) Freezing % in baseline (Bl) vs. first 5 min after AS onset (AS). n = 20 per treatment. Mean ± SEM are shown. *p’ < 0.05; **p’ < 0.01 and ***p’ < 0.001. (C) Freezing % over the 30 min test in 10 min bins. n = 20 per treatment. Mean ± SEM are shown. *p’ < 0.05; **p’ < 0.01 and ***p’ < 0.001.
