Inter-island movements of scalloped hammerhead sharks (Sphyrna lewini) and seasonal connectivity in a marine protected area of the eastern tropical Pacific (2014, background): “…when underwater is close to Fl. Visual surveys of reef fish have shown that lengths estimated visually underwater closely approximate both fork length and total length (Karpov et al. 2009), but true mean length may be underestimated due to the sinusoidal movement of fish (Harvey et al. 2002).”
What is Big BRUVver up to? Methods and uses of baited underwater video (2017, methodology): “…versus single-BRUVS and shown that the accuracy of fish length measurement using singleBRUVS deteriorated with distance from the measuring scale (±2 m) and angle of view ([50 ), while stereo gave a good estimate of length at a variety of angles and distances within 7 m (Harvey et al. 2002b).”
Action Cameras: Bringing Aquatic and Fisheries Research into View (2015, unknown): “…were commonly used in fisheries and aquatic research for assessing habitat (Carleton and Done 1995; Heithaus et al. 2002), estimating fish size (Harvey et al. 2002; Costa et al. 2006), characterizing community assemblage structure (Booth and Beretta 2002; Cooke and Schreer 2002), validating…”
Spatial prediction of demersal fish distributions: enhancing our understanding of species–environment relationships (2009, methodology): “For a detailed description, comparative analysis and review of this method, refer to Cappo et al (2003, 2004), Watson et al (2005), Harvey and Shortis (1996), Harvey et al. (2001a, 2001b, 2002).”
Underwater video techniques for observing coastal marine biodiversity: A review of sixty years of publications (1952–2012) (2014, background): “Stereo-275 video has been shown to provide more accurate estimates of both fish length and distance 276 than visual estimation by divers (Harvey et al., 2001a, 2001b, 2002a, 2004) or single video 277 14 (Harvey et al., 2002b).”
A little bait goes a long way: The influence of bait quantity on a temperate fish assemblage sampled using stereo-BRUVs (2013, background): “The need for trained and experienced observers to maintain the consistency and repeatability of research programmes can increase the field time and decrease the cost effectiveness of studies requiring in situ observers (Harvey et al., 2002; Langlois et al., 2010; Murphy and Jenkins, 2010; Willis and”
Cost-efficient sampling of fish assemblages: comparison of baited video stations and diver video transects (2010, methodology): “…on average, a greater number of individual reef fish species and 156 Langlois et al.: Baited video stations versus diver video transects greater abundance and/or biomass of generalist carnivore species than diver-operated stereo-video (stereoDOV) methods (Harvey et al. 2002, Watson et al. 2005).”
Behaviour of temperate and sub-tropical reef fishes towards a stationary SCUBA diver (2007, methodology): “Even small errors in length estimates could have a large influence on weight estimates, with error larger for those fishes that have an exponential length/weight relationship (Harvey et al. 2002).”
