This video was taken as part of a study into the influence of the Great Barrier Reef Marine Park Zoning on fish communities of the Great Barrier Reef. Pairs of shoals and reefs were compared, where one shoal was zoned 'green' (closed to fishing) and the other 'blue' or 'yellow' (open to line fishing). The demersal habitats and vertebrate communities were sampled using non-extractive Baited Remote Underwater Video Stations (BRUVS). These BRUVS revealed a diverse fauna of fish, sharks, rays and sea snakes, including species prized by fishers, taken as bycatch, or not vulnerable to hook and line fishing.
At each shoal multiple BRUVS (typically 12) were deployed, each recording 1 hour of underwater video. These videos were then viewed by an expert classifier and the relative abundance and species of fish and other vertebrates (such as seasnakes, turtles, whales and dolphins) seen in each video were measured and recorded.
The videos shown in this series (162 videos from all 1102 BRUVS) were selected to show the best 30 secs of the best 3 videos (based on the abundance of coral trout and red emperor) from each of the 48 study locations.
This video was taken by the Australian Institute of Marine Science (AIMS). [ Ссылка ]
