  abstract = {{T}he marine microbiome arouses an increasing interest, aimed at better understanding coral reef biodiversity, coral resilience, and identifying bioindicators of ecosystem health. {T}he present study is a microbiome mining of three environmentally contrasted sites along the {H}ermitage fringing reef of {L}a {R}{\'e}union {I}sland ({W}estern {I}ndian {O}cean). {T}his mining aims to identify bioindicators of reef health to assist managers in preserving the fringing reefs of {L}a {R}{\'e}union. {T}he watersheds of the fringing reefs are small, steeply sloped, and are impacted by human activities with significant land use changes and hydrological modifications along the coast and up to mid-altitudes. {S}ediment, seawater, and coral rubble were sampled in austral summer and winter at each site. {F}or each compartment, bacterial, fungal, microalgal, and protist communities were characterized by high throughput {DNA} sequencing methodology. {R}esults show that the reef microbiome composition varied greatly with seasons and reef compartments, but variations were different among targeted markers. {N}o significant variation among sites was observed. {R}elevant bioindicators were highlighted per taxonomic groups such as the {F}irmicutes:{B}acteroidota ratio (8.4%:7.0%), the genera {V}ibrio (25.2%) and {P}hotobacterium (12.5%) dominating bacteria; the {A}scomycota:{B}asidiomycota ratio (63.1%:36.1%), the genera {A}spergillus (40.9%) and {C}ladosporium (16.2%) dominating fungi; the genus {O}streobium (81.5%) in {C}hlorophyta taxon for microalgae; and the groups of {D}inoflagellata (63.3%) and {D}iatomea (22.6%) within the protista comprising two dominant genera: {S}ymbiodinium (41.7%) and {P}elagodinium (27.8%). {T}his study highlights that the identified bioindicators, mainly in seawater and sediment reef compartments, could be targeted by reef conservation stakeholders to better monitor {L}a {R}{\'e}union {I}sland's reef state of health and to improve management plans.},
