Inland Fisheries Ireland records first tagging of Atlantic bluefin tuna for 2024

Inland Fisheries Ireland has recorded the capture and tagging of the first Atlantic bluefin tuna of 2024.

The giant fish, measuring 1.68 metres, was caught, measured, tagged and released at Donegal Bay. 

In 2023, a total of 381 Atlantic bluefin tuna were tagged by authorised skippers in Irish waters.

Dr William Roche of Inland Fisheries Ireland (IFI) said: “The first fish of the season marks the start of a sustained period of data collection on bluefin tuna.

“Typically in summer, Atlantic bluefin tuna migrate to their feeding waters in Ireland in large numbers.

“This provides an excellent opportunity to tag tuna and collect data on when they appear in Irish waters, where they go, and what size they are.

“Any recaptures of tagged tuna will provide high-quality information on their wider migrations around the Atlantic Ocean, or the Mediterranean Sea, or further afield.

"IFI is very grateful to authorised skippers for their work on this large-scale information collection programme.”

Recreational angling for Atlantic bluefin tuna is technically prohibited in Ireland. 

However, through the Tuna CHART (CatcH And Release Tagging) programme, authorised charter skippers can capture, measure, tag and release bluefin during the 2024 season, which began on July 1st.

Bluefin tuna captures are kept in the water alongside boats, which progress slowly at speeds of 2-3 knots to ensure the fish remain in the best possible condition for their release.

Atlantic bluefin tuna average 2m in length in Irish waters, but can surpass lengths of 4m and weigh more than 600kg.

They are caught between approximately 1km and 20km off the coast of Ireland.

Skipper Adrian Molloy caught and released the first bluefin on Monday, July 29th and landed a second on the following day.

The 2024 Tuna CHART programme season runs until November 12th.
