Albacore fact sheet

Thunnus alalunga | Albacore

The albacore tuna, or simply albacore is characterised by having very long pectoral fins, leading to its name in portuguese "atum voador" which means "flying tuna". This species is known for its tireless fighting during the fishing season. They are found mostly in the upper 100 m of the water column, but can dive down to 800 m. Albacore inhabit tropical to subtropical regions with surface waters typically ranging from 15.6˚ C to 19.4˚ C, although they can tolerate temperatures as low as 9.5˚ C for short periods. This species is highly migratory, travelling in large groups/schools, typically more then 20 miles off the coastline. Albacore occur in the Azores during April and again from September to December, in coastal zones, open water and around seamounts. At the beginning of July they travel southwest to Spain, between July and August they travel to the Bay of Biscay and in the winter they migrate to the Caribbean.
