Can species-specific prey responses to chemical cues explain prey susceptibility to predation?

However, post hoc comparisons using Fisher's LSD test did not show any significant differences among species, although perch was preferred over roach at a nearly statistically significant level (perch α = 0.53, rudd α = 0.26, roach α = 0.21; species comparison: rudd vs. roach p = .370, rudd vs. perch p = .300, roach vs. perch p = .055; Figure 2 ). 4 DISCUSSION The experimental evaluation of the species‐specific reactions to the threat of catfish predation revealed that both roach and rudd were able to detect chemical cues and change their behavior under the threat of predation.
