The ongoing ultrasonic experiments of phase 2 of the Regional Tuna Project (Commission de l'Ocean Indien) are reported and analysed in relation to the local environmental parameters. Although 7 yellowfin tuna (Thunnus albacares) were tagged during the first 3 cruises of the project, only 5 of  them are considered in this paper, as they were tracked around FADs. Seasonal trends affect the horizontal movements associated with FADs: strong association and homing behaviour during the fishing season vs. weaker association when the fishing season comes to an end and the fish start migrating from the area. The vertical movements are analysed in order to provide a typology of the distribution of tuna in relation to different features (FAD association by day and at...

Tagging is considered an excellent tool for estimating the importance of interactions and competition between fisheries as well as to study tuna stocks and migrations. The Regional Tuna Project of the Indian Ocean Commission (IOC) conducted five tagging cruises in the western Indian Ocean, during which 955 fishes were tagged. Out of the total number tagged 15 were recaptured. Tuna tagging in the Indian Ocean was also undertaken by the Indo- Pacific Tuna Programme and by the Japanese National Research Institute of Far Seas Fisheries. 39 tuna marked by these organisations were recovered in Mauritius. Analysis of data collected from the tag recoveries provide some preliminary estimates of growth rate and migration of tuna. Tagging is the most direct method to...
