Satellites that are capable of detecting gamma-ray bursts can trigger the Antares neutrino telescope via the real-time gamma-ray bursts coordinates network. Thanks to the "all-data-to-shore" concept that is implemented in the data acquisition system of Antares, the sensitivity to neutrinos from gamma-ray bursts is significantly increased when a gamma-ray burst is detected by these satellites. The performance of the satellite-triggered data taking is shown, as well as the resulting gain in detection efficiency. Different search methods can be applied to the data taken in coincidence with gamma-ray bursts. For gamma-ray bursts above the Antares horizon, for which a neutrino signal is more difficult to find, an analysis method is applied to detect muons induced by the high-energy gamma rays from the source.
