Auditory thresholds for bighead and silver carp after sound exposure determined by the AEP technique: Data
Invasive silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp, collectively referred to as bigheaded carps, threaten aquatic ecosystems of the Upper Midwestern United States. Due to extensive ecological impacts associated with these species, prevention of their further range expansion is the aim for fisheries management. Recent behavioral studies indicate bigheaded carps are deterred by acoustic barriers and exhibit negative phonotaxis in response to anthropogenic sound sources (≥ 150 dB re 1 μPa SPLrms). However, the impact of long-term exposure to these sounds on the hearing capabilities of bigheaded carps has not been well documented. In this study, the auditory evoked potential (AEP) technique was used to determine auditory thresholds for both sound pressure (SPL) and particle acceleration levels (PAL) among bigheaded carps before and after exposure to high intensity (155.7 +- 4.7 dB re 1 μPa SPLrms; -8.0 +- 4.7 dB re 1 ms-2 PALrms; mean +- SD) broadband sound. Fish were exposed to sound for 30-min or 24-hr and AEP measurements were taken either immediately after exposure, 48-hr, or 96-hr later.
