A type of remote video system used by NOAA's Ecosystem Sciences Division (ESD) at the Pacific Islands Fisheries Science Center (PIFSC) is the baited remote underwater video station (BRUVS). The BRUVS was developed and several have been used widely by Euan Harvey, PhD, and colleagues at the University of Western Australia and the Australia Institute of Marine Science. BRUVS are similar to existing BotCam technology, but are more suitable for deployment on coral reef systems because they are smaller, lighter, and can be deployed closer to the substrate. Supported by the NOAA Coral Reef Ecosystem Program (CRCP), ESD uses BRUVS to conduct fish surveys to depths of ~100 m. Each BRUVS uses high-definition video cameras mounted 0.7 m apart on a base bar that is inwardly converged at 8°, set up as a stereo-video system. The video images from the cameras are subsequently analyzed to identify fish species and to determine fish sizes. The use of bait attracts a wide diversity of fish species into the field of view of the cameras, but ESD is also experimenting with unbaited deployments. The data provided in this data set—including fish species, counts, and lengths—were generated from the analysis of video footage from BRUVS surveys conducted during PIFSC missions in the Main Hawaiian Islands (MHI) in September 2012 and November 2013, and the Northwestern Hawaiian Islands (NWHI) in May and September 2014. Targeted fishes for measurement in the MHI included: all large-bodied predatory species, including sharks (Carcharhinidae), jacks (Carangidae), snappers (Lutjanidae), and the Hawaiian grouper (Cephalopholis argus. Select parrotfishes (Scarinae), goatfishes, chubs (Kyphosidae), and surgeonfishes (Acanthuridae) were also identified by PIFSC as species of interest. Targeted fishes for measurement in the NWHI included: all large-bodied predatory species, including sharks (Carcharhinidae), jacks (Carangidae), and the snapper Aprion virescens. Data are primarily collected to obtain a greater understanding of coral reef fish and roving predator populations between 0-100 m depths.

Where appropriate, deep-water scientists were also consulted in order to confirm identification of uncommon/rare species in mesophotic depths. Completeness Report All BRUV MaxN datasets (.csv files) are compiled from individual site outputs generated during annotation through the EventMeasure application (individual .txt files). Note: as of November 2017, the NWHI BRUVS data has only been annotated for roving predators (sharks/jacks/snapper), while MHI BRUVS targeted all fishes present. Conceptual Consistency All BRUVS data sets remain consistent with known, established protocols as described in literature. The count and size of reef fish observed on BRUVS surveys are manually logged by a video analyst. Each setup for a BRUV survey uses high-definition video cameras mounted 0.7 m apart on a base bar that is inwardly converged at 8°. All BRUVS, consisting of paired Sony handycams, are calibrated using CAL software (www.seagis.com.au; Seager 2008) according to well-published protocols (Harvey and Shortis 1998; Shortis and Harvey 1998) before and after each data collection effort. Following post-cruise video concatenation and conversion using the program Xilisoft, stereo-video files are reviewed with species annotated to the lowest possible taxonomic level using the program EventMeasure-Stereo (Seager 2008). Asher, Jacob M (808)725-5456 jacob.asher@noaa.gov processor The MaxN metric is used as the basis for abundance estimation (Ellis and Demartini 1995; Willis and Babcock 2000a; Willis, Millar et al. 2000b), with fork-length measurements obtained for a subset of target species at the time of MaxN. All species annotations are reviewed prior to analysis to ensure proper identifications, with quality control completed by one analyst to retain consistency across samples (Wilson, Graham et al. 2007). MHI Analysis: Analysts attempted to measure all fish within the MaxN by moving the video forward or backwards so they were not obstructed by other fish or benthos and close to the camera. Fork length measurements were only possible for fishes within the full field of view of each BRUV deployment, which are collected at the time of MaxN for each respective BRUV drop. E.g. any sightings at the time of MaxN, which recorded only part of the head/body, were not able to be measured. Finally, particularly for smaller fishes, fork-length measurements at the time of MaxN were not taken if sizing precision or root-mean-square rules were exceeded. NWHI Analysis: Length-based frequencies between predator groups were compared against the MHI. Fork lengths for groups other than the targeted species were not collected. Asher, Jacob M (808)725-5456 jacob.asher@noaa.gov processor All EventMeasure output .txt files are compiled into a .csv file, and imported into PRIMER Version 7.0.11 with PERMANOVA+ extensions or R-Studio for subsequent analysis.
