Atlantic bluefin tuna have returned to UK waters and can once again be seen during the summer and autumn months.
Their numbers appear to be increasing, following a long period of absence linked to population decline, according to research led by Cefas and the University of Exeter.
Marine scientists in the UK and Ireland have analysed multiple datasets, spanning a 16-year period, to document the increase in bluefin, which arrive into the waters of the Celtic Seas and off South West England, the Scilly Isles, and North West Ireland to feed in late summer and autumn.
The research is part of the Defra-funded “Thunnus UK” research project. MORE
