Previous studies on underwater acoustic pollution showed that noise affects vertebrates’ behaviour, like fish and marine mammals. However, little is known about other organisms. Consequently, we studied important lacking aspects, well known with chemical pollution: the effect on a key zooplankton species (used as bioindicator) and the effect on fitness (survival and fecundity). We exposed isolated water fleas, Daphnia magna, to chronic boat noise or to a silence broadcasted as control, from birth to death. We measured effects on lifespan and clonal offspring production (e.g., clutch size, number of produced offspring along life). We did not observe any effect of the chronic boat noise exposition on Daphnia’s fitness. These results are consistent with results on previous acute noise exposure, but also opposite to other ones found with acute and chronic noise effect. Thus, we discuss how the noise structure and temporal pattern could affect its impacts on aquatic organisms. Our work highlights that noise pollution should be integrated in ecotoxicological studies, but also that some particular aspects of this pollutant should be considered differently than chemical pollutants.Competing Interest StatementThe authors have declared no competing interest.
