A new study reveals Irish waters are a crucial haven for endangered basking sharks, based on nearly five decades of sighting data. Researchers analyzed records spanning almost 50 years to understand the sharks’ presence and behavior. The findings highlight the importance of continued conservation efforts to protect this vulnerable species. Ireland’s waters offer a significant refuge, potentially supporting a substantial portion of the eastern Atlantic basking shark population. This research underscores the need for monitoring and management strategies to mitigate threats like bycatch and disturbance. The long-term data set provides valuable insights into the sharks’ movements and habitat preferences, informing future protection initiatives. Further investigation will focus on the impacts of climate change and human activity on basking shark populations in the region.
