  abstract = {{T}his work, conducted on both reef and non-reef habitats of {R}eunion island, represents the first study on the coastal ichthyofauna structure at the scale of the whole island. {I}t aims at (1) describing and analyzing the dominant characteristics of fish communities, (2) identifying the main spatial patterns in the fish distribution, and then (3) interpreting the interactions between fish communities and environmental variables. {S}ampling was implemented using {U}nderwater {V}isual {C}ensuses ({UVC}) on twenty sectors distributed all along the island. coastline. {S}ixty-four families and 406 species were recorded. {F}or each species identified, diet, demographic strategy, geographical distribution and associated reef or non-reef habitats were attributed. {F}our ichthyological clusters, characterized by their environmental variables (substrate rugosity, energy of swell, current velocity, turbidity), were identified according to their geographical location. {T}he northern cluster was rich in planktivorous and non-reef habitat species, with a circumtropical distribution and relatively low fecundity, focusing their reproductive strategy on juvenile survival. {T}he southern one was rich in herbivorous fish and browsers of sessile,invertehrates, coral reef habitat species with high fecundity and low juvenile survival. {T}he eastern cluster was' composed of high proportion of south-western {I}ndian {O}cean species whereas the western one presented no ichthyological characteristic linked to any of the analysed environment variables. {T}he comparison between reef and non-reef fish communities showed that there was a high affinity between coral reef dependent species and environmental variables such as high rugosity and coral cover, also found outside the reef areas. {A}lthough this study was limited to the outer slopes of fringing reefs, the distinction between reef and non-reef communities could be mitigated by the small area, fragmentation and degradation of coral health in {R}eunion {I}sland, which promote the development of opportunistic and ubiquitous species at the expense of the characteristic species of coral reefs.},
