Abstract:
Chemical communication of predation risk has evolved multiple times in fish species, with conspecific
alarm substance (CAS) being the most well understood mechanism. CAS is released after
epithelial damage, usually when prey fish are captured by a predator and elicits neurobehavioural
adjustments in conspecifics which increase the probability of avoiding predation. As such, CAS is
a partial predator stimulus, eliciting risk assessment-like and avoidance behaviours and disrupting
the predation sequence. The present paper reviews the distribution and putative composition of
CAS in fish and presents a model for the neural processing of these structures by the olfactory
and the brain aversive systems. Applications of CAS in the behavioural neurosciences and neuropharmacology
are also presented, exploiting the potential of model fish [e.g., zebrafish Danio
rerio, guppies Poecilia reticulata, minnows Phoxinus phoxinus) in neurobehavioural research.
