2008 - Present | Ongoing Project


The All-Ireland visual tagging project is funded by the Heritage Council, Inishowen Development Partnership and supported by the Shannon Dolphin fund and Wildlife Foundation ( and the Irish Whale and Dolphin Group. This ambitious project has several aims and objectives.



  • Determine short term spatial and temporal movements of basking sharks found in Irish waters

  • Examine the annual and seasonal movements of basking sharks tagged in Irish waters

  • Identify important areas of concentration (i.e. "hotspots")

  • Use individual identification tags to observe interaction between identified and sexed sharks

  • Compile information on individual sharks to establish behavioural patterns and habits

  • Use individually-identified tagged sharks to record ecological and biological changes to a shark over time (e.g. size)

  • Use GIS mapping to correlate / identify trends in movements with possible determining factors
