Abstract: Since 2007, Ifremer together with the French Federation of Sport fishermen (FFPM) and Big Game Fishing Club France (BGFCF) have been carrying out a program of conventional and electronic tagging on bluefin tuna in the western Mediterranean Sea. 479 and 95 ICCAT “spaghetti” tags have been deployed by the FFPM recreational and sportive fishermen along the Mediterranean French coasts in 2007 and 2008, respectively. To date, not a single \nrecapture has been registered. Ifremer together with BGFCF has deployed 11, 6 and 8 pop-up archival tags (PAT) offshore of Marseille in 2007, 2008 and 2009, respectively. Outputs were impaired by two main technical difficulties: premature detachment and low transmission rates in the Argos band over the Mediterranean. While the first difficulty can be partially solved, the second remains a key limitation when using pop-up archival tags in this area. Preliminary\nresults are, however, of interest and indicate that (i) most tagged fish remained in the western Mediterranean Sea and did not migrate in the Atlantic but (ii), migration to the central Mediterranean Sea (Sicily or Gulf of Syrta) occurred during the spawning period, and (iii) a possible foraging ground has been detected South of the Gulf of Lions in both 2007 and 2008.
