  abstract = {{E}stimating diversity and abundance of fish species is fundamental for understanding community structure and dynamics of coral reefs. {W}hen designing a sampling protocol, one crucial step is the choice of the most suitable sampling technique which is a compromise between the questions addressed, the available means and the precision required. {T}he objective of this study is to compare the ability to sample reef fish communities at the same locations using two techniques based on the same stationary point count method: one using {U}nderwater {V}isual {C}ensus ({UVC}) and the other rotating video ({STAVIRO}). {UVC} and {STAVIRO} observations were carried out on the exact same 26 points on the reef slope of an intermediate reef and the associated inner barrier reefs. {STAVIRO} systems were always deployed 30 min to 1 hour after {UVC} and set exactly at the same place. {O}ur study shows that; (i) fish community observations by {UVC} and {STAVIRO} differed significantly; (ii) species richness and density of large species were not significantly different between techniques; (iii) species richness and density of small species were higher for {UVC}; (iv) density of fished species was higher for {STAVIRO} and (v) only {UVC} detected significant differences in fish assemblage structure across reef type at the spatial scale studied. {W}e recommend that the two techniques should be used in a complementary way to survey a large area within a short period of time. {UVC} may census reef fish within complex habitats or in very shallow areas such as reef flat whereas {STAVIRO} would enable carrying out a large number of stations focused on large and diver-averse species, particularly in the areas not covered by {UVC} due to time and depth constraints. {T}his methodology would considerably increase the spatial coverage and replication level of fish monitoring surveys.},
