Disturbance chemical cues determine changes in spatial occupation by the convict cichlid Archocentrus nigrofasciatus.

摘要: I studied the effect of disturbance chemical cues on fish that make trade-offs between foraging in an open area and remaining a safe refuge. used convict cichlids Archocentrus nigrofasciatus were either visually exposed to predator (n = 8) or water conditioned by from disturbed conspecifics 8). Fish decreased their ingestion rate spent more time refuge than area, while receiving frightened did not alter site, but increased spatial occupation (i.e., motion). These results suggest recognized visual cues. Moreover, are form threatening public information may increase due exploring behaviour; is sufficiently alarming feeding use.
