Description
Underwater visual census (UVC) and baited remote underwater video (BRUV) survey data of coral reef predator populations in North Malé Atoll, Maldives. The abundance of all coral reef predators was recorded and their size estimated (for UVC only). more

Using a combination of underwater visual census and baited remote underwater video, this study aimed to compare reef predator populations between inner and outer reefs of North Malé Atoll (Maldives) and determine which reef metrics may drive any differences in assemblage structure. Predator assemblages were significantly different between inner and outer atoll. Body sizes of several predator families were consistently larger in the outer atoll, however, abundance, biomass and species richness were similar between outer edge reefs and inner lagoonal reefs suggesting atoll lagoons may be undervalued habitats. Depth and complexity were consistently important predictors of the predator assemblage. Inner atoll lagoonal habitat is equally as important for reef predator assemblages as outward facing edge reefs, although species differ. This study provides important information on reef predator populations in the Maldives where detailed assessments of the reef predator assemblage are lacking but the reef fishery is thriving and annual catch will continue to increase.
