  abstract = {{S}ince the mid 1990s, the use of drifting {F}ish {A}ggregating {D}evices (d{FAD}s) by purse seiners, artificial objects specifically designed to aggregate fish, has become an important mean of catching tropical tunas. {I}n recent years, the massive deployments of d{FAD}s, as well as the massive use of tracking devices on d{FAD}s and natural floating objects, such as {GPS} buoys, have raised serious concerns for tropical tuna stocks, bycatch species and pelagic ecosystem functioning. {D}espite these concerns, relatively little is known about the modalities of d{FAD} use, making it difficult to assess and manage the impacts of this fishing practice. {T}he present paper provides an overview of a 4-year research on the use of d{FAD}s by tropical tuna purse seiners in the {W}estern {I}ndian {O}cean. {T}hough our primary objective was to derive information on d{FAD} fisheries from a large variety of quantitative sources of information ({GPS} buoy positions, onboard observers, logbooks and {VMS}), a multi-disciplinary approach was adopted throughout our research. {Q}uantitative results (estimates of d{FAD} use, fishing efficiency and impacts of d{FAD} use) were discussed with {F}rench purse seine skippers during semi-structured interviews to understand their perception of the impacts of d{FAD} use and to propose adapted management options for tropical tuna purse seine d{FAD} fisheries. {I}nterviews with {F}rench purse seine skippers revealed the existence of a competition between {EU} purse seine fleets, encouraging the recent increase in the use of d{FAD}s. {T}hey underlined the need for a more efficient management of the fishery, including the implementation of catch quotas, a limitation of the capacity of purse seine fleets and a regulation of the use of support vessels.},
