We are investigating the use of permanent magnets as behavioural deterrents for benthic (bottom-dwelling) shark species. These sharks frequently interact with baited hooks and nets, resulting in high levels of bycatch. This study aims to:

• Assess the effectiveness of different magnet types and configurations in repelling benthic sharks
  
  
• Quantify behavioural responses such as avoidance and the time taken to approach bait
  
  
• Identify species-specific sensitivity thresholds to magnetic fields
  
  

The findings will support the development of fishing gear modifications that reduce shark bycatch without affecting target species.
