Spawning Atlantic cod (<i>Gadus morhua</i> L.) exposed to noise from seismic airguns do not abandon their spawning site

Abstract Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes to abandon spawning grounds, reproductive success could be impacted. To investigate whether sound cod (Gadus morhua L.) leave their acoustic telemetry arrays were deployed on two grounds: a test reference site. From 2019 2021, 136 mature from the site 45 tagged with transmitters. Intermittent seismic shooting of 40 in.3 airguns for 1 week during periods 2020–2021 resulted in fluctuating exposure levels (SEL) site, comparable full-scale industrial survey 5–&amp;gt;40 km away. Residency survival analysed capture–mark–recapture models fitted detection recapture data. Departure rate varied between seasons but was similar sites. Neither nor departure significantly differed baseline periods. The results indicated that received SEL up ∼145 dB re µPa2 s, occurring several kilometres away, did not grounds.
