Brief description

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.

Notes

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.

Lineage

Fish, sharks, rays and seasnakes were included as 'fish'. There was a lack of data on spatial and temporal variation in fishing effort around the shoal habitats.
