During summer 2019, two acoustic surveys were conducted at 40 listening points distributed within the inlet areas of Venice (northern Adriatic Sea). Two five- minute recordings were collected per each point during both the boat traffic hours and the peak of the species\u2019 vocal activity with the aims of (1) characterizing the local noise levels and (2) evaluating the fish spatial distribution by means of its sounds. High underwater broadband noise levels were found (sound pressure levels (SPLs)50\u201320kHz 107\u2013137 dB re 1 \u03bcPa). Interestingly, a significantly higher background noise within the species\u2019 hearing sensibility (100\u20133150 Hz) was highlighted in the afternoon (113 \u00b1 5 dB re 1 \u03bcPa) compared to the night (103 \u00b1 7 dB re 1 \u03bcPa) recordings due to a high vessel traffic. A cluster analysis based on Sciaena umbra vocalizations separated the listening points in three groups: highly vocal groups experienced higher vessel presence and higher afternoon noise levels compared to the lower ones. Since the species\u2019 sounds are a proxy of spawning events, this suggests that the reproductive activity was placed in the noisier part of the inlets.","type_name":"Journal Article","journal_abbreviation":null,"pmid":null,"info_url":"https:\/\/bio.acousti.ca\/node\/58420"}]}
