Overview

Analysis reveals trends in bycatch rates of harbour porpoise and common dolphin in static net fisheries, indicating a need for improved mitigation strategies.

Key Points

  • Bycatch rates of harbour porpoise decreased while common dolphin rates increased since 2014, indicating diverging trends in marine mammal bycatch.
  • Utilizing acoustic deterrent devices reduced harbour porpoise bycatch by about 75%, but did not show a significant effect on common dolphin bycatch rates.
  • The study analyzed data from nearly 20,000 static net fishing operations between 1996 and 2023, assessing various environmental and operational factors.
  • Model predictions can help refine bycatch estimation and develop targeted strategies for reducing bycatch in fisheries.
