Tuna species, other pelagic fish, squid.
In the Eastern Atlantic believed from the Iberian Peninsula down to the Cape of Good Hope
Additional NotesEditKnown to grow above 1000lbs in weight. Another extremely rare vagrant to UK waters.
The pictures are of a 900 lb Atlantic Blue Marlin (brought in by my wife) being tagged and released off Madeira. The fish recovered and swam strongly away seconds after the third photo. It is difficult to do justice to such a large and handsome fish with boatside photos, but fortunately the practice of bringing marlin ashore for "trophy" shots has virtually ceased.
