Fish hearing and how it is best determined

Abstract Hearing, as defined by numerous investigators of vertebrate hearing, involves not only detection a sound, but the ability to respond sound behaviourally. Thus, in order understand what fish (or any animal) hears, it is important use behavioural methods that allow an animal “tell investigator” which sounds are detected and not. However, since 1980’s, most studies suggest they measuring hearing have used electrophysiological approaches measure response ear or lower levels central auditory system sounds. In this paper, we argue these measures do represent indicate can potentially while provide some useful interesting insights into mechanisms, valid sensitivity, understanding (anthropogenic otherwise) able to, obtained using studies. We also must be done carefully designed acoustic setups so nature stimulus responds appropriate well understood.
