  The ANTARES telescope, with a duty cycle close to unity and a full hemisphere
of the sky at all the times visible, is well suited to detect neutrinos
produced in astrophysical transient sources. Assuming a known neutrino
production period, the background and the sensitivity can be drastically
improved by selecting a narrow time window around it. GRBs, {\mu}-quasars and
AGNs are particularly attractive potential neutrino point sources since
neutrinos and gamma-rays may be produced in hadronic interactions with the
surrounding medium as they are the most likely sources of the observed ultra
high energy cosmic rays. A strong correlation between the gamma-ray and the
neutrino fluxes is expected in this scenario. ANTARES data has been analysed in
various transient source analyses with the goal of detecting cosmic neutrinos
from GRBs, {\mu}-quasars and AGNs. The sensitivity of a standard
time-integrated point source search can be improved by a factor 2-3 by looking
for neutrinos only during the most probable emission time. This information can
be provided by the different satellite telescope types on the X-rays and
gamma-rays wavelengths. The results of these different analyses will be
presented.
