BRUVS (TM) - Fish and Benthic survey of Rowley Shoals and Scott Reef (WA) 2003-06-01 to 2003-06-15

The dataset comprises 1299 individuals from 102 species of fishes, sharks, rays and sea snakes observed at 15 sites (Rowley Shoals and Scott Reef (WA)) using 68 baited remote underwater video stations (BRUVS(TM)). 232 images were captured from these cameras. Approximately 3500 of the best images from all BRUVS (TM) projects are stored in a reference library. Data recorded concern: - classification of the habitat in the field of view (topography, sediments, benthos) - the identity of fish and CAABCODES - their time of arrival - their behaviour (8 categories, including feeding on the bait) - their maturity (adult or juvenile) - their relative abundance (as MaxN = the maximum number visible at one time, or distinguishable at different times as separate individuals e.g. much larger/smaller, male/female) - the time elapsed before MaxN and feeding occurs. A custom interface has been developed by AIMS staff, using Microsoft Access, for reading and analysis of BRUVS(TM) tapes. In 2003, the deployment of BRUVS (TM) was investigated as part of a pilot study to develop non-destructive techniques for rapid assessment of shark abundance in northern Australia. These data were later included in a larger study of reefs within the MOU74 Box and the Rowley Shoals, with the following aims: 1) to sample fish and shark assemblages at Ashmore and Cartier Reefs within the MOU74 Box (historically fished reefs, now Marine Protected Areas - MPAs) and Clerke and Imperieuse Reefs (unfished reefs) in the Rowley Shoals. 2) to integrate data from the 2003 BRUVS (TM) surveys (Scott Reef- presently fished, MOU74 Box, and Mermaid Reef, MPA, Rowley Shoals) into results to provide a comprehensive picture of the status of shark stocks within the MOU74 Box in comparison to unfished reefs (Rowley Shoals) nearby. 3) to provide a preliminary assessment of the status of reef fishes on Ashmore and Cartier Reefs within the MOU74 Box (historically fished reefs, now MPAs) in comparison to Clerke and Imperieuse Reefs (unfished reefs) in the Rowley Shoals. In recognition of the long standing use of marine resources of northern reefs as a small scale, traditional fishery, the Australian and Indonesian governments negotiated a memorandum of understanding (MOU74) that allows access by Indonesian fishermen to an area of 50,000 km² within the Australian Exclusive Economic Zone (AEEZ). Within this area lie 6 coral reef systems, the northern most of which are Ashmore and Cartier Reefs. Concern over the status of stocks of reef resources targeted by Indonesian fishermen led to a ban on all fishing at Ashmore Reef in 1988 and at Cartier Reef in 2000. One small area of the West Island lagoon of Ashmore Reef was made exempt from this restriction to allow subsistence fishing by crews. The primary aim of this restriction was to allow over-fished stocks of bêche-de-mer and trochus to recover. While a variety of surveys had concluded that there was little evidence that reef fishes had been over-exploited on reefs within the MOU74 Box, there was little evidence on which the status of shark resources could be assessed. The child records attached to this record refer to benthic BRUVS (TM) deployments only.
