Main Article Content


Underwater Visual Census (UVC) and Baited Remote Underwater Video (BRUV) are broadly used methods to study fish assemblages in marine and estuarine environments. This study compared the results of BRUV and UVC methods for assessing seasonal trends in coral reef fish assemblages in a marginal reef in the northern Persian Gulf. In doing so, seasonal surveys of coral reef fishes were done using BRUV and UVC methods. Comparison of assemblage metrics driven from each method indicated that both methods may reveal similar patterns of seasonal changes in fish and trophic group assemblages while there may be between-method differences in species richness, total abundance, and trophic group abundances. The observed differences may be related to the longer sampling times of BRUV.
