  Gamma-ray bursts are thought to be sites of hadronic acceleration, thus
neutrinos are expected from the decay of charged particles, produced in
p{\gamma} interactions. The methods and results of a search for muon neutrinos
in the data of the ANTARES neutrino telescope from four bright GRBs (GRB
080916C, GRB 110918A, GRB 130427A and GRB 130505A) observed between 2008 and
2013 are presented. Two scenarios of the fireball model have been investigated:
the internal shock scenario, leading to the production of neutrinos with
energies mainly above 100 TeV, and the photospheric scenario, characterised by
a low-energy component in neutrino spectra due to the assumption of neutrino
production closer to the central engine. Since no neutrino events have been
detected in temporal and spatial coincidence with these bursts, upper limits at
90% C.L. on the expected neutrino fluxes are derived. The non-detection allows
for directly constraining the bulk Lorentz factor of the jet {\Gamma} and the
baryon loading fp.
