  abstract = {{T}he role of habitat at different spatiotemporal scales in structuring fish communities is nowadays universally recognized. {F}rench {G}uiana, with a dense hydrographic network and high fish species richness, constitutes an adapted field to test some hypotheses about fish-habitat relationships. {T}his paper aims at synthesizing the actual knowledge on the environmental variables determinant in structuring fish communities in {F}rench {G}uiana rivers. {H}istorical factors linked to the alternation of glacial and inter-glacial episodes explain the peculiar distribution of fish species in an {E}ast-{W}est gradient. {T}he number of fish species in the basins matches the general relationship between basin area and fish richness observed in other {A}mazonian rivers. {T}he zonation of fish species along the course of rivers is poorly marked with only two zones identified, excluding the headwaters which are largely unknown. {A}t the reach scale creeks and pools house distinct fish communities but no fish species is exclusive of the rapid habitat. {I}n the creeks as well as in the pools many statistical relationships have been found between environmental variables and the presence and/or abundance of individual fish species. {G}old mining and the presence of a dam are the main human activities that influence fish communities' structure through modification of the aquatic environment.},
