Abstract

Anthropogenic activities are causing increased noise levels in the marine environment. To date, few studies have been undertaken to investigate the effects of different noise frequencies on juvenile fishes’ behaviour. In this study we evaluate the behavioural changes of juvenile gilthead seabream (Sparus aurata) exposed to low frequency noise for 7 hours. The emitted sounds were white noise filtered at 1/3 octave band centred at 63, 125, 500 and 1000 Hz (Sound Pressure Level: 140-150 dB re 1µ?a). For each frequency (plus control with no sound) three independent trial replicates were performed. The dispersion (group dispersion), motility and swimming height of the fish were analysed before and during the acoustic emission. Gilthead seabreams were found to be more sensitive to the lowest frequencies but exhibited different response and habituation behaviours depending on the particular frequency.
