Climate change forcing bluefin tuna further north away from Irish coast, study finds

The study monitored the tagged fish for up to 12 months once they left Irish waters. Some fish travelled to the Mid-Atlantic while others travelled to the Mediterranean Sea, possibly to spawn, while several tagged tuna returned to Ireland the following year.

Climate change off the Irish coast is leading the giant Atlantic bluefin tuna to move north in search of cooler habitats, a new scientific study has found.

Electronic tags placed on the species, which normally live around Irish waters during the summer, showed they are spending more time toward higher latitudes as the region experiences ocean warming events.
