This dataset includes exported hydroacoustic data (i.e., coordinates for acoustically detected fish targets, mean target strength of detected fish). The distance (m) from the water guns for each fish target was calculated using the gps coordinates of fish targets and the water guns’ location. The total lengths of fish targets were estimated from their target strength (dB), and fish were then classified as native fish or bigheaded carp according to their total length. This dataset was used to examine the efficacy of water guns to alter bigheaded carp behavior via analyses on fish abundance, spatial and size distribution of fish, and the effective water gun range. Each worksheet tab is labeled with the survey date and time, as well the water gun treatment (i.e., control, off, on).
