Fathead minnows, Pimephales promelas , exposed to acidified water (pH = 5.0) for 72 h continued to respond normally to the alarm substance (Schreckstoff) contained in water extracts of conspecific skin. This result contrasts with an earlier finding that some behavioral responses to chemical feeding stimuli are lost at relatively high pH levels (pH = 6.0). In combination, the two sets of results indicate that different stimulus/response systems have different thresholds for interference by acidification.
