Morphological Correlates Of Auditory Sensitivity In The Inner Ear Of Two Species Of Invasive Carp, Tyler Patty
Mahurin Honors College Capstone Experience/Thesis Projects
Silver (Hypopthalmichthys molitrix) and bighead (H. nobilis) carp, are invasive species that have negative impacts upon ecosystems. H. molitrix is known to jump completely out of the water in response to broadband sounds, however, this is not observed in H. nobilis. Preliminary experiments reveal that sounds can be used to modify the behavior of carps. Thus, understanding the hearing abilities of these species is important in order to design appropriate acoustical deterrents. Fish heads were preserved in 4% paraformaldehyde and the inner ears dissected and photographed under a light microscope in order to describe the …
