Anglers across Galway are taking part in a unique catch, tag and release programme to help Irish and international scientists learn more about the largest tuna in the world – the Atlantic bluefin tuna.
Under the Tuna CHART programme, recreational anglers on board two authorised charter vessels in Galway will be catching bluefin tuna and skippers will be tagging and releasing them back into the sea, alive, from July to November this year.
The vessels will be operating out of Cleggan and Rossaveal and the data collected on board authorised vessels will then be used for scientific assessment to improve knowledge of population structures, fish size and how bluefin tuna is distributed in Irish waters and throughout the North Atlantic.
Migrating through North Atlantic waters, bluefin tuna frequent Irish coastal waters to feed. Bluefin is an iconic sports angling species and can grow up to 1,500 lbs (approximately 680 kgs ).
Under strictly-controlled conditions, 685 bluefin tuna were caught, tagged, measured and released through the Tuna CHART programme in 2020. All bluefin tuna were caught by anglers in Irish coastal waters and then tagged by skippers. The fish is always kept in the water to ensure correct handling and tagging; the largest tuna tagged in Ireland in 2020 was 2.75 metres long, estimated to weigh over 800 lbs (approximately 360 kgs ).
Now in its third year, the programme has been a successful collaboration between Inland Fisheries Ireland and the Marine Institute in partnership with the Sea Fisheries Protection Authority, the Department of Agriculture, Food and the Marine and the Department for Environment, Climate and Communications.
Key role of the skippers acknowledged
Eamon Ryan TD, Minister for the Environment, Climate and Communications said the 22 angling vessels authorised by hisDepartment will contribute substantially to essential Bluefin tuna data collection as they migrate along the Irish coastline. The recreational fisheries sector is crucial in the delivery of this data collection programme and we look forward to continue working with all the State agencies involved. I want to acknowledge the key role of the authorised charter skippers and their crews who are bringing their unique expertise to bear on providing valuable data for scientific purposes, and the ‘citizen scientist’ anglers who will catch the fish. The fact that 685 fish were tagged last year with no mortalities recorded is a great achievement by the skippers.”
Under the tagging programme, twenty-two angling charter vessels in total have been authorised to take anglers fishing for bluefin tuna on a catch, tag and release basis, during the open season. All skippers have been fully trained while vessels have been fitted with a customised GPS device. Data is collected by skippers digitally by means of a specifically designed app.
The authorised vessels operate out of ports in Donegal (Killybegs and Bundoran ), Sligo (Rosses Point and Mullaghmore ), Galway (Cleggan and Rossaveal ), Clare (Carrigaholt and Kilrush ), Cork (Courtmacsherry, Kinsale, Ballycotton, Union Hall, Great Island in Cobh, Baltimore and Youghal ) and Waterford (Dungarvan ).
Anglers looking to fish for bluefin tuna in Irish waters may only do so from an authorised charter vessel from now until 12th November 2021. The Sea Fisheries Protection Authority and Inland Fisheries Ireland are undertaking inspections and patrols around the coast to ensure that no unauthorised vessels are targeting or catching bluefin tuna.
Both organisations have also confirmed that any person engaging in fishing for bluefin tuna on a vessel which is not appropriately authorised, would be in breach of the Sea-Fisheries and Maritime Jurisdiction (Bluefin Tuna ) Regulations 2019 (S.I. No. 265 of 2019 ) and would face prosecution.
Like last season, skippers will have to adhere to any local or national Covid-19 public health guidelines that may be put in place. A full list of authorised skippers and vessels for the Tuna CHART programme in 2021 can be found at www.fisheriesireland.ie/bluefin
