Overview

Experimental analysis of fish community changes due to a seismic survey, suggesting minimal impact on diversity.

Key Points

  • No significant changes in fish community structure were observed after a seismic survey, indicating low impact.
  • A total of 102 fish genera were detected, with more identified through baited remote underwater video stations than eDNA.
  • eDNA collected within a BACI framework efficiently monitored fish community responses to noise from seismic activities.
  • Results imply that eDNA metabarcoding is a valuable tool for ecological assessments alongside traditional methods.
