    Acoustic and chemical conditioning and retention for behavioral deterrence in invasive bigheaded carps (Hypophthalmichthys molitrix and H. nobilis)
    (2023-05) Culotta, Jackie
    Invasive bigheaded carps (Hypophthalmichthys molitrix and H. nobilis) are two aquatic invasive species that are expanding their range throughout the Mississippi River Basin. These carp display negative phonotaxis to broadband sound and thus acoustic deterrents have shown promise for managing their populations. Numerous dams block direct upstream access for the carp; however, fish can bypass these physical obstructions by swimming though navigational locks. Nonphysical acoustic deterrents have the advantage of not effecting navigation, are relatively inexpensive, and could be tuned above the hearing range of non-ostariophysian fishes. Fish also react negatively to high levels of carbon dioxide, and it has been proposed to combine these two stimuli into one deterrent system to reduce potential habituation to long term acoustic playbacks and increase barrier efficacy. Here, the possible synergies of combining these two stimuli into integrated deterrent systems are evaluated.

    Raw Data from Silver, Bighead, and Common Carp Acoustic Avoidance tests, December 2013 - February 2014
    (2017-02-16) Sorensen, Peter W; Zielinski, Daniel P; dzielinski@usgs.gov; Zielinski, Daniel P
    Raw data of fish position and sound measurements from acoustic avoidance tests with silver, bighead, and common carp. The data is made available to support a open access publication submitted to PLOSONE entitled "Silver, bighead, and common carp orient to acoustic particle motion when avoiding a complex sound."
