Surveys were undertaken in February/March and August/September 2007 (Autumn and Spring) and October 2009 (Spring) on two pairs of discrete deepwater shoals in the mid-shelf section of the southern Great Barrier Reef - East and West Warregos; Karamea and Barcoo Banks. Within each pair, one shoal was from a 'Green' (closed to all fishing) and the other from a 'Blue' (open to fishing) zone, based on the rezoning carried out in 2004. The demersal vertebrate communities were sampled using non-extractive Baited Remote Underwater Video Stations (BRUVS), which revealed a diverse (c250 species) fauna of fish, sharks, rays and seasnakes.Variables recorded:Habitat composition of underlying substratum (sand, rubble, consolidated outcrop or reef), and epibenthic community (hard coral, soft coral, sponge, macroalgae, whips and gorgonians, encrusting organisms, bare substratum) - estimated from BRUVS field of view as percentage cover of each component, to nearest 10%.Zone (Green, G; or Blue, B); Reef name; Habitat class (coral - coral dominated reef; garden - gorgonian and seawhip garden; rubble - low relief rubble field; sand - open sandy seabed); Depth (m; or shallow, deep); Latitude and longitude (ship's GPS position at deployment); Trip (1 - February, autumn; 2 - August/September, spring). In some (stereo) BRUVs the size of fishes was recorded (mm).Fish species were placed in categories depending on the likelihood of being caught and retained by line fishers:(a) 'Highly sought after reef dwelling species' - the most desirable reef dwelling species based on eating qualities and size, as well as their reef dwelling habits.(b) 'Sought after reef dwelling and pelagic species' - as in (a) plus pelagic and semi-pelagic species, and smaller, acceptable food fishes.(c) 'All species considered likely to be caught by line fishers including by-catch' - as in (b) plus the undesirable fishes that form by-catch.(d) 'Species considered unlikely to be caught by line fishers' - all species unlikely to be hooked because of their dietary preferences or small size.

To describe the fish fauna in relation to habitat and spatial and temporal variables on selected deep shoals of the GBRMP.To present baseline fish community data from BRUVS surveys of two pairs of 'blue'(open to fishing) and 'green' (closed to fishing) zoned shoals in the GBRMP.
