Assessing reef fish assemblage structure: how do different stereo-video techniques compare? (2010, background): “Harmelin-Vivien et al. 1985; Samoilys and Carlos 2000 ).”
Coral reef cascades and the indirect effects of predator removal by exploitation (2004, methodology): “Fish and starfish densities were estimated using SCUBA underwater visual census (UVC) in replicate 7 m radius point counts (Jennings & Polunin 1997; Samoilys & Carlos 2000).”
Bait attraction affects the performance of remote underwater video stations in assessment of demersal fish community structure (2007, background): “Underwater visual surveys by SCUBA divers in shallow waters, and by observers from submersibles in deeper waters, have enabled density estimates to be made for a variety of species in a range of habitats (e.g. Samoilys & Carlos 2000, Yoklavich et al. 2000).”
Size structural change in lightly exploited coral reef fish communities: Evidence for weak indirect effects (2004, background): “The lengths and numbers of individuals >8-cm fork length were estimated for 182 diurnally active, reef-associated species from 18 families (Jennings and Polunin 1997; Samoilys and Carlos 2000; Dulvy et al. 2002).”
Factors affecting the detection distances of reef fish: implications for visual counts (2011, background): “Similar trends have been reported for point count surveys with different sampling radii (Bohn-sack and Bannerot 1986; Samoilys and Carlos 2000; Minte-Vera et al. 2008).”
Potential of video techniques to monitor diversity, abundance and size of fish in studies of Marine Protected Areas (2003, background): “Consequently, there has been much research interest in Rapid Assessment Techniques for initial surveys and robust monitoring techniques that balance field costs and data quality with the need for very long data series (e.g. Samoilys and Carlos 2000; Samway and Hatton 2001).”
Comparing environmental DNA metabarcoding and underwater visual census to monitor tropical reef fishes (2020, background): “UVC is traditionally used to monitor fish diversity on coral reefs (Samoilys & Carlos, 2000).”
Fishing groupers towards extinction: a global assessment of threats and extinction risks in a billion dollar fishery (2013, background): “The good news is that most shallow to medium-depth groupers lend themselves well to fishery-independent sampling, such as from underwater visual census surveys (e.g. Samoilys and Carlos 2000; Nemeth et al. 2007).”
Use of natural marks on population estimates of the nurse shark,Ginglymostoma cirratum, at Atol das Rocas Biological Reserve, Brazil (2005, methodology): “Underwater visual surveys have been used extensively in reef fish studies of population dynamics, ecology and management (see review by Samoilys & Carlos 2000), providing precise and relatively accurate density estimates (Zeller & Russ 2000).”
Latitudinal gradients in Atlantic reef fish communities: trophic structure and spatial use patterns (2004, methodology): “Assembling data from different sampling methods is always problematic for statistical purposes, however, in a recent method re-evaluation, Samoilys & Carlos (2000) did not find significant differences between transect and point-count visual censuses for many taxa.”
A comparison of two survey methods: differences between underwater visual census and baited remote underwater video (2010, unknown): “After waiting 2 min for the disturbance of their arrival to dissipate (Samoilys & Carlos 2000), the observer swam slowly in a pre-determined direction, looking ahead as well as under ledges and in the kelp understory, identifying and counting fish in a strip 5 m wide.”
Abundance estimates of the Indo-Pacific lionfish Pterois volitans/miles complex in the Western North Atlantic (2006, background): “One visual transect was completed per site (Sanderson and Solonsky 1986; Samoilys and Carlos 2000; Schmitt et al. 2002).”
Impact of observers experience level on counts of fishes in underwater visual surveys (2006, background): “…vary depending on the detectability and behavioral characteristics of target groups (Lincoln Smith 1989, Cheal & Thompson 1997, Kulbicki 1998, Samoilys & Carlos 2000), and so we wanted groups to be broadly similar in those respects, while still reflecting as much as possible the kinds of…”
