  abstract = {{A}utomated acoustic receivers are now widely used by biologists to study the behavior of fish. {H}owever, currently available acoustic receivers require physical recovery of the units to download stored data. {S}uch operation is often difficult in remote study areas like in the open ocean. {W}e present a new satellite-linked acoustic receiver ({V}emco {VR}3-{A}rgos) that allows downloading data through a satellite uplink ({A}rgos). {T}he {VR}3-{A}rgos can last up to one year, sending {GPS} positions and tag data at regular time intervals. {W}e illustrate the advantages of this new technology with tagging data from 121 fish of seven species (yellowfin tuna, bigeye tuna, skipjack tuna, wahoo, dolphinfish, silky shark and oceanic triggerfish) caught and released around drifting fish aggregating devices ({FAD}s) in the {W}estern {I}ndian {O}cean, far from any land. {I}n opposition with the classic acoustic receivers ({V}emco {VR}2), the use of {VR}3-{A}rgos allowed to collect data for several weeks after leaving the drifting {FAD}s. {M}aximum residence times of 3 days for bigeye tuna, 7 days for skipjack, 8 days for wahoo, 10 days for silky shark and 15 days for yellowfin tuna, dolphinfish and oceanic triggerfish could be recorded. {VR}2 and {VR}3-{A}rgos are equivalent in terms of quality of residence times data, however depth data obtained through satellites are aggregated in 8 classes for compression purposes, which leads to a loss of precision available with raw data. {F}uture directions of this technology are discussed.},
