Bighead carp (Hypophthalmichthys nobilis), silver carp (H. molitrix) (hereafter: bigheaded carps), and common carp (Cyprinus carpio) are invasive fish causing negative impacts throughout their North American range. To control their movements, non-physical barriers are being developed. Broadband sound (0.06 to 10 kHz) has shown potential as an acoustic deterrent for bigheaded carps, but the response of common carp to broadband sound has not been evaluated. Since common carp are ostariophysians, possessing Weberian ossicles similar to bigheaded carps, it is possible that sound can be used as an acoustical deterrent for all three species. Behavioral responses to a broadband sound were evaluated for common carp in an outdoor concrete pond. Common carp responded a median of 3.0 (1st Q: 1.0, 3rd Q: 6.0) consecutive times to the broadband sound which was lower than silver carp and bighead carp to the same stimulus. The current study shows that common carp demonstrate an inconsistent negative phonotaxis response to a broadband sound, and seem to habituate to the sound quickly.
