Avoidance of areas marked with a chemical alarm substance by fathead minnows (Pimephales promelas) in a natural habitat

Abstract

Minnows exhibited significant avoidance of traps marked with conspecific alarm pheromone. There was a nonsignificant tendency for minnows in control traps to be larger than those caught in experimental traps, suggesting a possible role of experience or developmental factors in determining the response to alarm pheromone. There was no apparent difference in overall body condition (length-specific mass) between minnows that were caught in control versus experimental traps.
