Thunnus (Thunnus) is sometimes referred to as the bluefin group and comprises five species: subgenus Thunnus (Thunnus) T. alalunga (Bonnaterre, 1788) – albacore; T. maccoyii (Castelnau, 1872) – southern bluefin tuna; T. obesus (Lowe, 1839) – bigeye tuna; T. orientalis (Temminck and Schlegel, 1844) – Pacific bluefin tuna
In 2000 a 76-year-old pensioner using a fishing rod for the first time landed the largest tuna caught off the British Isles for nearly 50 years. Off the north-west coast of Ireland Alan Glanville caught a 353-pound (160 kg) fish and next day caught one of 529 pounds (240 kg). [ 2 ]
