Abstrakt: Animals can use a variety of sources of information to learn about local predation threats, including the behavior of conspecifics. Socially-acquired information about predation risk has been demonstrated in a variety of fish species, so the phenomenon is likely taxonomically widespread. Threespine stickleback fish are a geographically widespread species that encounters a variety of native and introduced predators throughout its range; as such, learning to recognize predators may be an important component of survival. We assessed whether laboratory-bred, predator-naïve stickleback could learn to fear the odor of a live rainbow trout by first observing videos of conspecifics exhibiting antipredator responses in the presence of trout odor. We found that this is not the case: following one conditioning trial in which trout odor was paired with videos of frightened conspecifics, stickleback did not exhibit an increase in antipredator behavior (e.g., a decrease in activity or an increase in hiding) in the presence of trout odor. Although there is evidence that stickleback use social information to find foraging patches, it does not appear that they do the same to learn about predation threat, at least in the context of our experimental conditions.
