Gadoids (codfish) gather at particular locations to spawn,where they exhibit complex reproductive behavior with visual and acoustic displays. Gadoid species are most sensitive to sounds from 30 to 500 Hz. Gadoid hearing can be masked by ambient sound but also by anthropogenic sounds, which may therefore adversely affect their reproduction, with potential effects upon discrete local stocks.Listening for gadoid sounds provides a reliable, non-invasive way of locating spawning sites, which can enhance the protection of reproducing fish from human impacts.This paper puts together a review of what is known about the bioacoustics of gadoid fishes and then considers the potential impacts of anthropogenic sound on this group of animals.
