Repeated antipredator conditioning: a pathway to habituation or to better avoidance?
Hatchery‐reared juveniles of Arctic charr Salvelinus alpinus were conditioned to the odours of Arctic charr‐fed pikeperch Sander lucioperca in the absence of any other cues. Accordingly, there was no physical threat of capture for the Arctic charr. It was evident from the subsequent survival tests t...
