Visual Census of Reef Fish Assemblages: A Comparison of Slate, Audio, and Video Recording Devices


Fish assemblage data were recorded using slate, audio, and video techniques with a point-count visual census technique under controlled conditions. The community variables (number of species, number of individuals, and species diversity) describing the assemblage were generally similar for all three recording methods but audio recorded parameters were higher in magnitude. Slate and audio techniques were more similar to each other than each was to video with regard to the assemblage variables. Community resemblances were high for pairwise comparisons for all three recording methods. Users should be aware that certain species are more likely to contribute to differences in faunal comparisons than others. The simultaneous recording of fish assemblage date in situ using audio/video is recommended.
