The first tagged tuna were released by the project at the beginning of May 2005 in Seychelles waters.For all tagged fish were recorded: Tag number, Species, length, tagger, cradle, date and position as well as quality codes whenever necessary.Thons marqués durant le programme RTTP168,164 tuna were tagged and released including: - 54,684 Yellowfin or 32.5% - 34,569 Bigeye or 20.6% - 78,332 Skipjack or 46.6% - 579 species unknown or 0.3%22,858 tuna were double-tagged (DT) or 16.6%5,944 tuna were OTC tagged or 3.5%.289 archival tags (XX recovered) giving pressure, temperature, light data.6 pop-up tags (XX recovered).Pas de poids à la capture pour le marquage, juste la taille, toujours LF.les observations réasliées sur les individus marqués comportent la localisation, l'espèce, taille, numéro de tag ( éventuellement deux tags),The data are gathered in an ACCESS Data Base. The database also contains data on the vessel’s activities, bait fishing, sightings, catch on deck, biological data, electronic tagging, tag recoveries re-released. These data are on different tables linked together (ACCESS). A Tagging Manual describes in details all data and codes.This dataset is the one provided by IOTC (extracted from MasterTagging Access database which stores only data collected during the scientific cruises (some recoveries but only for individuals caught multiple times by vessels of the project).Miscellaneous Data : Bait fishing: all baiting sets were recorded with their catch. Bait samples were taken, species were indentified and measured. We only kept the average, the min and the max of the bait lengths.Activities and sightings were recorded with some environmental data.All schools were recorded and as well as other items related to tuna occurrence (cetaceans, logs, FADs, current lines, etc…).All successive recoveries in the AS were all documented.Précision GPS pour les individus marqués.
