Effects of Pile Driving on the Residency and Movement of Tagged Reef Fish

ABSTRACT

The potential effects of pile driving on fish populations and commercial fisheries have received significant attention given the prevalence of pile driving occurring in coastal habitats throughout the world. Behavioral impacts of sound generated from these activities on fish typically have a greater area of influence than physical injury, and may therefore adversely affect a greater portion of the local population. This study used acoustic telemetry to assess the movement, residency, and survival of 15 sheepshead (Archosargus probatocephalus) and 10 grey snapper (Lutjanus griseus) in Port Canaveral, Florida, USA, in response to 35 days of pile driving at a wharf complex. No obvious signs of mortality or injury to tagged fish were evident from the data. Received sound pressure levels from pile strikes on the interior of the wharf, where reef fish primarily occur, were on average 152–157 dB re 1 μPa (peak). No significant decrease in sheepshead daytime residency was observed during pile driving within the central portion of the wharf and area of highest sound exposure, and no major indicators of displacement from the exposure wharf with the onset of pile driving were observed. There was evidence of potential displacement from the exposure wharf that coincided with the start of pile driving observed for 2 out of 4 grey snapper, along with a decrease in daytime residency for a subset of this species with high site fidelity prior to the event. Results indicate that snapper may be more likely to depart an area of pile driving disturbance more readily than sheepshead, but were less at risk for behavioral impact given the lower site fidelity of this species.

Each symbol represents a single day fish was present; shading indicates the period of pile driving.

Mentions: Individual detection data were examined to determine timing of departure from the exposure basin (Fig 4). Two sheepshead left the exposure basin before pile driving began; sheepshead ID4 moved into the control basin while sheepshead ID6 was never detected again. The remaining sheepshead stayed in the exposure basin for the duration of pile driving, with the exception of sheepshead ID5 that left on day 10 of pile driving, and returned 21 days after pile driving ended.
