Fish is extremely sensitive to low-frequency vibrations, below some 10s of Herz. If the sound source is sufficiently intense, fish usually respond by swimming away from the source. The reason for this is probably that low frequency sounds usually indicates an approaching predator.
What are the most sensitive fish?
Diadromous fishes depend on migrations between marine and freshwater habitats. They are considered the first most sensitive due to this highly specialized lifestyle (McDowall, 1999, Britton and Pegg, 2011). Potamodromous fish essentially migrate in freshwaters and were thus considered second sensitive.
Do fish have sensitive hearing?
While the inner ears are sensitive to sound, and to linear and angular acceleration of the fish body, the lateral line is primarily sensitive to local water movements relative to the fish surface (Dijkgraaf, 1963).
