Minnows gave a fright response when exposed to skin extract (chemical alarm cue) and an artificial visual light stimulus. When they were retested with light stimulus alone, the minnows that had previously been conditioned with alarm cues and light exhibited anti-predator behavior in response to the visual cue. To carry out this experiment, we hypothesized that fathead minnows would learn to associate predator risk stimulus with visual stimulus, and they would be capable to differentiate between the three different colors by showing associate response to the red color and no response to the green and blue lights. The results of this experiment have far-reaching implications because they provide important information on the role of visual stimuli in the ecological environment of fishes.en-USItascaMinnesotaPimephales promelasfathead minnowsScholarly Text or Essay
