Assessing Caribbean Shallow and Mesophotic Reef Fish Communities Using Baited-Remote Underwater Video (BRUV) and Diver-Operated Video (DOV) Survey Techniques - Fig 4

<p><b>Fish abundance per species on (A) shallow reefs, and (B) mesophotic reefs, using BRUV and DOV methods calculated across all sites.</b> Only species comprising >1% of the total number of fish recorded are shown. Abundance represents the mean number of fish recorded per 250m² DOV transect, or per BRUV drop for DOV and BRUV surveys respectively.</p

Assessing Caribbean Shallow and Mesophotic Reef Fish Communities Using Baited-Remote Underwater Video (BRUV) and Diver-Operated Video (DOV) Survey Techniques - Fig 5

<p><b>Fish length frequency distribution for (A) shallow and (B) mesophotic reefs recorded by DOV and BRUV across all sites.</b> Grey shaded areas represent one standard error either side of the null model, <i>n</i> = number of individual fish measured, <i>p</i> indicates whether the length distributions are significantly different based on permutation tests.</p
