6,370 kilometres across the Atlantic Ocean. That is the vast distance, as the crow flies, which has been covered by an albacore tuna tagged and released into the sea off a Gipuzkoan locality, 20 km to the north of Donostia-San Sebastian (Spain) in October 2006.
The specimen has recently been caught by Venezuelan fishermen just off the coast of their country. This is a record distance covered by an albacore tuna among those registered by the ICCAT-The International Commission for the Conservation of Atlantic Tunas.
When the specimen was tagged, it was a year old, 50 cm long and weighed 2.5 kg. When it was recaptured six and a half years later it weighed 21.8 kg and measured 100 cm. Tuna tagging is routine practice to find out, among other things, about their migrations and how big the populations of these species are.
