  abstract = {{M}esophotic marine ecosystems are characterized by lower light penetration supporting specialized fish fauna. {D}ue to their depths (-30--150 m), accessibility is challenging, and the structure of mesophotic fish assemblages is generally less known than either shallow reefs or deep zones with soft bottoms which are generally trawled. {E}nvironmental {DNA} metabarcoding from seawater filtered in situ could improve our ability to monitor the diversity of mesophotic ecosystems. {H}ere, we developed and tested a submersible standalone pumping device allowing targeted marine water filtering to explore the biodiversity of two mesophotic ecosystems, one temperate along the {P}rovence coast in the {N}orth-{W}estern {M}editerranean {S}ea and one tropical at the seamount {L}a {P}{\'e}rouse in the {W}estern {I}ndian {O}cean. {W}e filtered water samples from depths ranging between 0 and 200 m in the {M}editerranean {S}ea and between 60 and 140m in the {I}ndian {O}cean and applied a metabarcoding protocol using the teleo primer pair targeting the 12{S} mitochondrial r{DNA} ({A}ctinopterygii and {C}hondrichthyes). {F}or both study regions, our e{DNA} surveys were able to recover highly diverse fish assemblages, and the compositional analysis of e{DNA} samples showed both a marked signal of fish compositional turnover and overlapping taxa between depth zones. {F}urther, we observed that a substantial number of species were found in samples collected in depths beyond their reported depth range suggesting an underestimation of species'depth tolerances. e{DNA} metabarcoding should thus complement existing knowledge of species'geographic distributions across space and depth. {O}verall, our results demonstrate the potential of e{DNA} metabarcoding for future mesophotic surveys as it allows fast and broad biodiversity assessment.},
