| Abstract |
Neogobius melanostomus (round goby) are a benthic dwelling invasive species of fish in the Great Lakes. This study was done to determine if a tone that mimics the frequency (175 Hz) of mating call of a male round goby would have an effect on male and female response. A testing tank and a simulated trap in front of a speaker at each end were used. Each fish was then placed individually into the small holding box that was in the center of the tank. A video camera was then turned on to record fish movement once the door was opened. Next, the artificial sound was turned on for 1 min (175, 300, 500 Hz, and no sound); 175 Hz mimics the conspecific mating call. This process was done for each frequency for each fish. The individual fish was then allowed to roam for 5 min. The video camera recorded fish location and behavior. From the videos, a continuous measure was collected according to when the fish crossed the center line. The hypothesis, if (N. melanostomus) hears different frequencies of sound projected from a certain location in a fish tank habitat, then the females will be attracted and spend more time on the sound-emitting side of the tank, which mimics the frequency of mating call of a male round goby (175 Hz, 13 pulse), was supported; females spent more time on the sound-emitting side of the tank and males avoided the sound-emitting side of the tank, analysis of variance p < 0.012. |
