Abstract:
Understanding spatio-temporal patterns of top predators can be crucial
for evaluating key habitats, assessing the effects of anthropogenic
activity and consequently applying suitable management policies. Here,
we characterized dolphins acoustic occurrence and interactions with
boat presence and noise in the waters of the Sicily Strait. A
hydrophone was deployed on an elastic beacon three miles off the coast
of south-west Sicily, and recorded continuously for 14 months, from
January 2015. Results revealed that packed and train clicks types were
the most detected signals, suggesting that animals were especially
involved in feeding activity. A regular year-round acoustic presence
was recorded, with seasonal variability. Two peaks were detected
during the year in August and November, concurrently with a possible
increase in fish biomass in the area. An abrupt decrease in click
detection rate in September coincides with the biological shutdown in
2015 and the shift of fishing vessels offshore, suggesting a possible
movement of dolphins following trawlers. Furthermore, dolphins
vocalized more during the night-time, probably carrying out movements
to and from the coast. Results indicated that dolphins interact with
trawlers during mid-morning when an intermediate level of activity was
collected, but click detection rate decreased with increasing noise
levels at one-third octave bands centered at 250 Hz. Outcomes can help
inform conservation efforts and the development of monitoring
programmes focused on environmental impact assessments under the EU
Marine Strategy Framework Directive.
