In monitoring studies, these sounds can be used to detect and identify species. However, being able to confidently link a sound to the correct emitting species requires precise acoustical characterization of the signals in controlled conditions. For practical reasons, this characterization is often performed in small sized aquaria, which, however, may cause sound distortion, and prevents an accurate description of sound characteristics that will ultimately impede sound-based species identification in open-water environments. This study compared the sounds features of five specimens of the silverspot squirrelfish Sargocentron caudimaculatum recorded at sea and in aquaria of different sizes and materials. Our results point out that it is preferable to record fish sounds in an open-water environment rather than in small aquaria because acoustical features are affected (sound duration and dominant frequency) when sounds are recorded in closed environments as a result of reverberation and resonance. If not possible, it is recommended that (1) sound recordings be made in plastic or plexiglass aquaria with respect to glass aquaria and (2) aquaria with the largest dimensions and volumes be chosen. specialized 120 034 154 1 270-278 2023 0001-4966 https://www.documentation.ird.fr/hor/fdi:010090047 10.1121/10.0020149 0001-4966 [F B010090047] https://www.documentation.ird.fr/hor/fdi:010090047 https://www.documentation.ird.fr/intranet/publi/2023-09/010090047.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-09-22 2025-02-24 fdi:010090047 fre
