The much-publicized threats to coral reef systems necessitate a considered management response based on comprehensive ecological data. However, data from large reef systems commonly originate from multiple monitoring programs that use different methods, each with distinct biases that limit united assessments of ecological status.

Journal of Experimental Marine Biology and Ecology, 2012
Abstract Fish communities associated with a series of artificial reefs deployed in three estuaries in southeastern Australia (151° 34′ E, 33° 7′ S to 150° 37′ E, 35° 8′ S) were surveyed using both Baited Remote Underwater Video (BRUV) and Underwater Visual Census (UVC).

Biased underwater visual census biomass estimates for target-species in tropical reef fisheries
Journal of Fish Biology, 1995Visual census biomass estimates are compared with yields of three emperor (Lethrinidae) genera from shallow water fished reef habitats and we demonstrate that visual census can consistently underestimate the exploitable biomass of Lethrinus spp.

Detection of spatial variability in relative density of fishes:comparison of visual census, angling, and baited underwater video [PDF]
Marine Ecology - Progress Series, 2000 The ability to make accurate estimates of fish relative abundance is the basis of both ecological and environmental effects studies, and flawed sampling methods may give misleading results even in otherwise well-designed surveys. This paper compares surveys of snapper Pagrus auratus (Sparidae) and blue cod Parapercis colias (Pinguipedidae) conducted ...

A comparison of two survey methods: differences between underwater visual census and baited remote underwater video [PDF]
Marine Ecology - Progress Series, 2010 Essential to any model, conservation or management plan are measures of the distribution and abundance of a species. Countless methods for estimating these parameters exist, making it essential to assess the limitations and biases associated with a particular sampling protocol.

Performance of transect and point count underwater visual census methods [PDF]
Ecological Modelling, 1997 A simulation approach was used to study bias and variability of density estimates of fish using the transect and point count underwater visual census methods. Three experiments were conducted to examine the effects of fish density, sampling effort, and the speed of fish in relation to the observer. Fish density and sampling effort did not significantly
