Shore-based belt transects were conducted at 1 to ~ 5 m depths at a total two (2) sites: at 2 longshore sites on the leeward coast (South Kohala district) of the Big Island (Hawaii Island) in the MHI during spring-summer 2009. For recruit reef fish survey, twenty (20) randomly positioned transects were surveyed at each site or site-group in 2009. Each transect was 50-m long x 2-m wide (100 m**2 area). Raw survey data consist of species-specific and size-specific (total length, TL, in cm) numerical counts of recruit (≤ 5 cm total length, TL) reef fishes encountered within transect boundaries. For predator reef fish survey, twenty (20) randomly positioned transects were surveyed at each site or site-group in 2009. Each transect was 50-m long x 4-m wide (200 m**2 area). Raw survey data consist of species-specific and size-specific (total length, TL, in cm) numerical counts of large juvenile and adult (≥ 6 cm total length, TL) stages of PREDATOR reef fishes encountered within transect boundaries. Inclusion as a predator fish in the transect tally was based on either known or likely (based on functional morphology) inclusion of small fishes in the species' diet. For recruit-habitat survey, the recruit-habitat relations (habitat use by recruits) were surveyed at 1 to ~5 m depths based on all 'Encounters' of singletons and 'groups' (where a group comprised > 1 recruit associating with one another and within 10-cm distance of one another), along transects conducted at a total two (2) sites on the leeward coast (South Kohala district) of the Big Island (Hawaii Island, in the MHI) during spring 2009. The substrate type closest to recruits encountered within transect swaths were recorded as one or more of fourteen (14) main taxonomic and functional habitat types.

During May 2007 and May and Nov 2008 a total of 305 individuals from 46 fish species were collected with line or spear under the approval of the Department of Environment and Conservation (permit numbers SF006335, CE001989 and SW012041). Reef-based fishes were collected from one of seven sites that traverse the reef, from reef slope to lagoon (thumbnail), while pelagic species were caught by trolling along the reef slope in the vicinity of stations 6 and 7. Paired tissue and gut samples were taken to determine stable isotope ratios of carbon and nitrogen and fatty acid analysis

Baited Remote Underwater Video Stations (BRUVS (TM)) were deployed in coastal waters between Quondong Point and Coulomb Point, to sample demersal and semi-demersal fishes, sharks, rays and sea snakes. Of the 197 BRUVS (TM) deployed, 154 produced imagery of sufficient quality to classify the benthic substratum, epibenthic cover and to identify and count vertebrates.BRUVS (TM) were deployed below the 5 metre depth contour (lowest astronomical tide) and placed at random within a grid of the entire study area (30x14 km), at spacings not less than 450m apart, to avoid double counting of more mobile fish. Surveys were completed around the neap tides in mid October 2009. Habitats dominated by stony corals were not sampled because they occurred intertidally, or in waters too shallow for access by the survey vessel. Baited Remote Underwater Video Stations (BRUVS (TM)) were deployed to provide baseline estimates of the diversity and relative abundance of demersal and semi-demersal fishes, sharks, rays and sea snakes in the James Price Point coastal area in direct relation to habitat and depth.

The biennial Alaska Fisheries Science Center's (AFSC) Gulf of Alaska (GOA) bottom trawl survey are an integral component of stock assessments and management of fishes and crabs in the region. However, the image set was used for deep sea coral and sponge identification and annotation. Each transect was 15 minutes long with a vessel speed close to 1 knot. The lowered stereo camera system (LSC) was kept within 1 m of the bottom during the transect. The start of each transect was haphazardly chosen. Most transects took place at night. The LSC system consisted of two parallel-mounted machine-vision cameras spaced approximately 30 cm apart in underwater housings connected via ethernet cables to a computer in a separate underwater housing enclosed in a protective aluminum cage. A monochromatic/color camera pair was used with image resolution. The monochromatic camera (Point Grey, BFLY-PGE_50S5M) collected images at 5.01 megapixels, and the color camera (Point Grey, BFLY-PGE_50S5C) collected images at 5.01 megapixels. Four high intensity strobe LED illuminators provided lighting and were activated at the surface when the camera unit entered the water and deactivated at the end of the deployment when the unit returned to a depth of approximately 10 m. Each strobe was constructed of two Cree CXB3590 arrays capable of producing 25,000 lumens at 200 W. The computer, cameras, and lights were powered by a 28 V NiMH battery pack. Synchronous images were recorded at a frequency of one image per second. Images were processed with software that allowed direct measurements to be made from calibrated stereo camera images.

This dataset derives from deployments of pelagic baited camera systems (stereo-BRUVS) conducted within the Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea during September and October 2012 onboard the RV Solander. This resource comprises species lists and relative abundance data (measured as MaxN, the maximum number of individuals of a given species captured in any one frame) for 116 sampling sites surveyed across three focal areas. The Oceanic Shoals Commonwealth Marine Reserve survey was undertaken as an activity within the Australian Government's National Environmental Research Program Marine Biodiversity Hub and was the key component of Research Theme 4 - Regional Biodiversity Discovery to Support Marine Bioregional Plans. Hub partners involved in the survey included the Australian Institute of Marine Science, Geoscience Australia, the University of Western Australia, Museum Victoria and the Museum and Art Gallery of the Northern Territory. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; sub-bottom acoustic profiles; physical samples of seabed sediments, infauna and epibenthic biota; towed underwater video and still camera observations of seabed habitats; baited video observations of demersal and pelagic fish, and; oceanographic measurements of the water column from CTD (conductivity, temperature, depth) casts and from deployment of sea surface drifters.

Baited remote underwater video stations (BRUVS (TM)) were deployed to census deep water fish communities (30-70 m) at 19 sites in South Scott Reef lagoon in November and December 1999. The sites were selected to cover nominally representative habitat types and depth contours across 6 regions of South Scott Reef lagoon. These regions, were East Hook Entrance, East Hook, East Lagoon, Central Lagoon, South Lagoon and West Lagoon. A total of 112 deployments were made along three transects running outward from the centre of South Scott Reef lagoon to both East Hook and West Hook and to the southern shallow region, as well as along the drop-off at the entrance to the lagoon. Six BRUVS (TM) were deployed at each site, at similar depths, separated by intervals of approximately 150 m. A GPS fix was taken for all BRUVS (TM) deployed. Each BRUVS (TM) was lowered to the seafloor, with an attached rope and surface float marking its position, enabling recovery later in the day. Normal daily operations were to deploy all six units in one site during the morning, followed by a second deployment at a new site in the afternoon. As a test, on one occasion, two BRUVS (TM) were deployed at night with underwater torches attached for illumination. Each BRUVS (TM) recorded onto a 90 minute Hi-8 video tape until the tape was full. The deployed units were recovered after the maximum recording time and generally within 4 hours of deployment. Tapes were scanned on a Sony Trinitron 14 inch Monitor using a Sony Video Hi-8 Cassette Recorder with a Sony Control Unit editing deck. This allowed fast-forward, play-back, zoom X2 and freeze to enable definitive species identifications, and to speed data collection. Data collected from each tape included a brief description of the seabed topography and benthic community, a species name, the time (hr:min:sec) of first sighting of the individual species, the species activities/behaviours (in 6 categories) in the field of view, the time that an individual species began to feed at the bait canister and/or the time at which the most number of individuals was active in the field of view, and the maximum number of each species sighted simultaneously in any one field of view. These data were initially entered into a Microsoft Excel spreadsheet. This study was undertaken to determine species richness and diversity of fishes, sharks, rays and sea snakes below the limits of safe SCUBA diving in South Scott Reef lagoon, using baited remote underwater video stations (BRUVS (TM)).BRUVS (TM) data was used in combination with benthic community data derived from surveys with television recordings from a remotely operated vehicle (ROV) to provide;1. a statistical clustering by similar fish communities of the different habitats and regions in the South Scott Reef lagoon and2. a measure of association between fish communities and broad habitat classifications. This study was part of a more extensive survey of North Scott Reef lagoon and South Scott Reef lagoon, "Characterisation of Scott Reef lagoon biota - fish and macrobenthos" carried out during November and December, 1999. Work in North Scott Reef lagoon focused on shallow water benthic communities, which were sampled by the divers using hand-held underwater video cameras. Sampling in South Scott Reef lagoon used more diverse methods and focused on not only the benthic communities but the demersal fish communities as well. In South Scott Reef lagoon the benthic communities were sampled using divers, ROVs and grabs, while fish communities were sampled using deployed baited remote underwater video stations (BRUVS (TM)).

Towed camera transects were conducted in the Great Australian Bight (GAB) and near St Helen's Hill seamount during the pilot survey for estimating the effectiveness of spatial closures for deepwater gulper sharks and associated fishery species. There are large gaps in ecological knowledge of gulper sharks which limit the effective design of area closures (e.g. optimising sizes and numbers) and assessment of their performance. The survey aimed to fill these gaps do this by characterising the habitats and ecosystem processes in 200-700 m depths that sustain key species, and commencing a process to determine the relevant aspects of species ecology. Primarily this will be (1) to measure the movement of fish within and to/ from a large closed area in the GAB with a tagging program, and (2) estimate the abundance of selected species in relation to habitat features (substructure within submarine canyons, escarpments and rocky banks, and adjacent water column features) with two independent, non-extractive photographic methods. This metadata record refers to the image data collected during the survey. The image annotations collected for this project will added to the Oracle data base BHIMAGE and the associated videos and still images have been archived as described in MarLIN record 14436 'Benthic Habitats Video Image Archive'.

This dataset contains the catch data from seasonal gillnet and longline surveys of shark nursery areas in the Central Section of the Great Barrier Reef Marine Park (2011-2014). Methods: Sampling occurred seasonally in nine bays along ~ 400 km of the tropical north Queensland coastline: Rockingham, Halifax, Cleveland, Bowling Green, Upstart, Abbott, Edgecumbe, Woodwark/Double and Repulse Bays. Of these nine bays, five were sampled regularly, the others (in italics) were sampled only once as part of a broader survey. Sampling sites were dominated by silty substrates, and mudflat and/or mangrove-lined foreshores. Between October 2011 and November 2013 eight rounds of fisheries-independent surveys were undertaken to collect data on the shark community across the study region. Within each bay sampling occurred randomly within sixteen 0.9 km wide strips running perpendicular to the shore. Two groups of eight strips were placed within each bay to spread the sampling across different habitat types and management zones (i.e. gill-net fishing allowed and gill-net fishing prohibited) where possible. During each round, each bay was sampled over four days allowing for two days of sampling in each group of strips. The bays vary in size and so the relative proportion of area sampled varied between bays. Two methods were used to sample across a broad range of shark sizes. During a total of 183 days of sampling, 453 longline shots and 343 gill-net shots were deployed totaling 370 and 310 h, respectively. Bottom-set gill-nets, comprised of 11-cm-stretched mesh, were deployed for ~ 1 h and checked every 15 min to facilitate tagging and release. In accordance with the Great Barrier Reef Marine Park Authority’s Dugong Protection Areas, multiple panels of net were joined to create a total net length of either 200 m or 400 m. In addition, some 100-m gill-nets were used during the Jan/Feb round in 2012. Bottom-set longlines were comprised of 800 m of 6-mm nylon mainline with an anchor and float at both ends. Gangions were attached to the mainline ~ 8–10 m apart; and were comprised of 1 m of 4-mm nylon cord, 1 m of 1.5-mm wire leader, and a baited 14/0 Mustad tuna circle hook. A variety of fresh and frozen baits were used including butterfly bream (Nemipterus sp.), squid (Loligo sp.), blue threadfin (Eleutheronema tetradactylum) and mullet (Mugil cephalus). Up to two longlines were deployed simultaneously for 40–90 min sets. Environmental data (water temperature, salinity, depth, turbidity and oxygen saturation) were recorded for all sets. Captured sharks were identified to species level, tagged on the first dorsal fin (Rototag or Superflex tag; Dalton, Oxfordshire, UK), measured, sexed, assessed for clasper calcification, examined for umbilical scar condition, and released at their capture site. Stretch total length was determined according to Compagno (1984). Small sharks (? 1 m) were placed ventral side down on a measuring board and measured to the nearest mm with the upper lobe of the caudal fin depressed in line with the body axis. Larger sharks were secured beside the boat and measured to the nearest cm using a measuring tape. Additional measurements of fork length and pre-caudal length were recorded. Format: CSV File, 4432 rows (~1MB), Shapefiles (4409 Points) Each line of data represents the catch of an individual shark, ray, fish, etc. Multiple lines exist per shot if more than one animal was caught. The shapefile was created by the eAtlas for visualisation purposes. It retains most of the information in the CSV as a point shapefile. The point shapefile was created from the CSV using the Start_Lat and Start_Long as the coordinate for points. If rows which did not have a valid Start_Lat or Start_Long (29 rows) then the End_Lat and End_Long were used instead (6 rows). If neither of these were available then the row was ignored. This removed 23 rows. Attributes Lat and Long were added to contain the coordinates used in the shapefile, leaving the

This dataset relates to deployments of pelagic stereo-BRUVS conducted by the University of Western Australia within and to the west of the Bremer Marine Park in February/March 2017. The survey was undertaken to provide a baseline assessment of the pelagic assemblages occurring in the region as part of the NESP Marine Biodiversity Hub Emerging Priorities Project #EP2 (https://www.nespmarine.edu.au/project/ep2-surveying-marine-life-canyons-bremer-bay). A total of 791 individuals from 13 taxa were identified.
