Abstract

Fish chorusing is a long-duration reproductive vocal behavior that dominates marine acoustic environments. Black drum are among the loudest chorusing fishes and have a range from Massachusetts to Florida, yet the spatial distribution of their chorusing behavior has never been examined across their range. Using acoustic data from 2015-2018 along the US Atlantic coast, I examined the occurrence of black drum chorusing events. Of the 80 acoustic recorders evaluated, chorusing was found in three at two recording sites, Georgia and South Carolina. Environmental parameters correlated with chorus duration, start time, and onset were found. Through modeling, sea surface temperature and salinity were found to be key predictors of the onset of chorusing at the Georgia and/or South Carolina recording sites. These results indicate that black drum chorusing requires certain combinations of oceanographic parameters to occur and that these vocalizations can maybe be used as an indicator of ocean change.
