A baited remote underwater video station (BRUVS) is generally considered an appropriate sampling tool for fish. The applicability of BRUVS to determine the substrate coverage was assessed by comparing stills from BRUVS videos to traditional point intercept transect (PIT) data to estimate percentage cover (PC) of different benthic substrate categories. Mean PCs of hard corals, rock, sand, and coral growth forms yielded statistically identical values with the two survey methods, while PCs of motile epibenthic invertebrates were underestimated by BRUVS in areas of both high and moderate relief. Yet, multivariate analyses revealed that the two methods yield similar substrate assemblage in an area of moderate relief. Results of our study suggest that the BRUVS can be effectively used to quantify both the presence/absence of a basic set of benthic habitat characteristics and diversity of coral growth forms on coral reefs in the Persian Gulf.
