Silver and bighead carp frequency detection was evaluated in response to 100 Hz to 9 kHz using auditory evoked potentials (AEPs). AEPs, consisting of measured minimum Sound Pressure Levels (SPL; dB re 1 ms-2) and Particle Acceleration Thresholds (PAT; dB re 1 ms-2). SPL and PAT were recorded every 100 Hz from 100 Hz to 1000 Hz plus 1500, 2000, 3000, 4000, and 5000 Hz for five individual Silver Carp and five individual Bighead Carp. Minimum detectable PAT and SPLs were measured at 100, 200, 400, 600, 800, 1000, 2000, 4000, and 5000 Hz for three individual Common Carp.
