After the detection by the IceCube Collaboration of the neutrino event IC170922A
in coincidence with the flaring blazar TXS 0506+056 in 2017, a huge effort has
been done to further find spatial and temporal correlations between high-energy
neutrinos and flaring electromagnetic sources. In 2019 this effort has resulted in
two promising associations between neutrinos observed by the IceCube detector
and the tidal disruption events AT2019dsg and AT2019fdr. More recently, in De-
cember 2021, the IceCube Collaboration reported the detection of the high energy
event IC211208A potentially correlated with the blazar PKS 0735+17 in a fla-
ring state, as confirmed by several optical observatories. Furthermore, the Baikal-GVD Collaboration and Baksan Underground Scincitillation Telescope have each reported the detection of a spatially compatible neutrino candidate during this flaring period.

The ANTARES neutrino telescope has proven to be a powerful tool in neutrino as-
tronomy benefiting from the accurate pointing due to the light scattering proper-
ties of the Mediterranean Sea. In the analysis presented in this contribution, the
data collected by the ANTARES telescope during the flaring emission of PKS 0735+17
are investigated to look for neutrino candidates spatially correlated with the blazar. The analysis strategy, which exploits both binned and unbinned methods,
together with the obtained results is presented.
