Abstract (EN): A shark tagging programme along the Portuguese coast was initiated in 2001 in collaboration with the National Marine Fisheries Service. From a total of 168 blue sharks (Prionace glauca) tagged, 34 sharks were recaptured (20% return rate) providing important information on this species' movement patterns for the area. A total of 28 sharks travelled less than 1000 km while at liberty for time periods ranging from 22 to 1294 days. The remaining fish travelled long distances to north-west Africa, central Atlantic and the Bay of Biscay. Only one shark made a transatlantic migration, being recaptured 3187 km from the tagging site. North-south movements seem to be related to seasonal sea-surface temperature variation in the north-east Atlantic. Seasonal segregation of different life stages also occurs.
