Abstract :
[en] Mesophotic Coral Ecosystems remain largely unexplored. The aim of this study was to determine how the acoustic fsh biodiversity varied depending on the depth and the type of island in six Polynesian islands. The link between benthic cover and fsh sound diversity was established. In most islands, acoustic fish α-diversity decreased between 20 and 60 m but not between 60 and 120 m. Fish sound types community composition was more driven by depth, likely due to benthic coral cover diferences, than by the type of island. These results show fish sounds exhibit a bathymetric stratifcation and can refect diferent habitat features. It opens perspectives in the monitoring of mesophotic coral ecosystems using passive acoustics.
