Overview

Pilot study shows that pingers reduce acoustic activity of Burmeister’s porpoise, suggesting effectiveness in bycatch mitigation.

Key Points

  • Pingers reduced Burmeister’s porpoise acoustic activity by 20%, indicating potential for decreasing bycatch.
  • Significantly more clicks were detected at night, confirming nocturnal foraging patterns of Burmeister’s porpoise.
  • Acoustic behaviors were analyzed continuously for 27 days in Mejillones Bay during the austral summer.
  • Future applications of pingers in fishing nets could minimize bycatch risks for the near-threatened porpoise species.
