As urban development across the globe increases, the acoustic environments that surround us alter with the addition of new sounds. Our aquatic ecosystems are prime examples of altered acoustic environments as levels of anthropogenic noise within our waters have risen dramatically within the past decade. This has developed concern for a number of aquatic animals that rely on the use sound to communicate since their ability to detect acoustic signals directly impacts their survival and reproductive fitness. In order to determine how marine organisms are affected when living near dense cities, we examined the impacts of anthropogenic noise on oyster toadfish (Opsanus tau) calling behavior. Oyster toadfish, commonly found in the Hudson River, are an ideal model as they depend on detecting conspecific vocalizations for reproduction. It was hypothesized that anthropogenic noise would occur most frequently during the daytime compared to after dark, and that oyster toadfish may space their calls to avoid masking. This study aimed to quantify anthropogenic noise as well as oyster toadfish vocalizations and was carried out by collecting passive acoustic recordings in the Hudson River (New York, New York). Using Audacity Software, noise was categorized and number of occurrences over a 24-hour period were recorded. It was found that anthropogenic noise can be heard within the oyster toadfish’s hearing range (80-800 Hz) and occurs most frequently during the daytime.
