Survey/Project Name: Baited Underwater Video Surveys (BRUV) - MER MARINE PARKS
Abstract: This project aims to assess change within priority South Australian (SA) marine park sanctuary zones, and compare this to suitable control sites outside the sanctuary zone, using Baited Remote Underwater Video Systems (BRUVS). In the SA marine parks context, BRUVS are used to monitor change in fish assemblages in reef, seagrass and occasionally sand habitats (identified as key ecological values in the Marine Park monitoring, evaluation and reporting program. BRUVS work by using a bait to attract fish species, capturing those fish on video, then later using that video footage to identify, count and measure the variety of fish and invertebrate species that were seen. BRUVS are a core tool for assessing the performance of SA's marine parks network. Data feeds into Global Archive. BDBSA holds a copy of 2015/2016 data only.

Methodology
         Vegetation: *** No vegetation methodology recorded
         Fauna: The location and frequency of sampling will be guided by the Marine Parks MER Plan and annual operational plans that factor in changes to available resourcing and priorities. It is anticipated that some Sanctuary Zones (SZ's) will be sampled annually and others less frequently. Sampling is conducted primarily during the warmer months of November to May when water temperatures are higher and daylight hours are longer. As much as possible, individual sites are resurveyed at the same time of year to reduce seasonal biases. At individual priority monitoring marine park sanctuary zone, three sites are surveyed inside and 3 outside the zone, with 4 replicate BRUVS samples at each site (separated by a minimum 200 metres to maintain a level of independence). Where possible, zones and sites are selected in such a way that broader spatial patterns (e.g. spatial and physical gradients) can be considered in comparisons of multiple in and out sample sets. Standardisation of habitat types, depths and oceanographic conditions is also sought to minimise background variability between sites.
