Leiden: Brill Academic Publishers, v. 149, n. 9, p. 941-951, 2012.0005-7959http://hdl.handle.net/11449/17809We examined whether pintado catfish (Pseudoplatystoma corruscans) can discriminate between scents of non-injured conspecifics stressed by a predator or by confinement and how fish use this information in the trade-off between feeding and predator avoidance. In the confinement stress condition, fish ingested the food, whereas in the predator stress condition, fish did not eat. This finding and comparisons of the latency to food ingestion and the time spent swimming between the confinement and predator-stress conditions indicated that pintado catfish can discriminate between conspecifics stressed by a predator or confinement using chemical cues, and use this information for adjusting the trade-off between food intake and predator avoidance.941-951engchemical cuesstressantipredator behaviorpredator avoidancefeeding behaviorcatfishPseudoplatystoma corruscansArtigo10.1163/1568539X-00003022WOS:000311973400004Acesso restrito59867844357279800000-0003-4591-4415
