Effects of amplitude and duration of noise exposure on the hearing and anti-predator behaviour of common roach (Rutilus rutilus) and sand goby (Pomatoschistus minutus)

Open Access Peer Reviewed Research Article 2023

Journal of the Acoustical Society of America

Maurer, N., Baltzer, J., Schaffeld, T., Ruser, A., Schnitzler, J.G., Siebert, U.
Differentiation of amplitude vs duration of nose exposure, controlled for cumulative energy, in relation to anti predator behaviour. This was examined in regard to a vessel slowdown as a management strategy to decrease vessel noise impact on fishes. results show that a reduction in vessel speed with a corresponding reduction in source level could mitigate the effects on the auditory senses of sensitive fish but does not appear to have any mitigating effect on their noise-induced behavioural changes.
