Key Points

• Species Overview:
  • Atlantic bluefin tuna, historically abundant in Irish waters, face threats from overfishing and climate change.
• Climate Impact:
  • Warming seas are causing tuna to migrate north, impacting marine ecosystems and coastal communities.
• Research Efforts:
  • Trinity College Dublin and Irish Marine Institute tracked tuna migration using satellite tags.
• Findings:
  • Some tuna travelled to the Mid-Atlantic and Mediterranean, with several returning to Ireland the following year.
