Fig. 4 in A novel method to obtain accurate length estimates of carnivorous reef fishes from a single video camera

Fig. 4. Boxplots showing the length distributions (mm) for Acanthistius patachonicus in five Submarine Parks within Golfo Nuevo, estimated by the naive (n = 132), Reference scale at the bait level (RSB) (n = 98) and Mirrored baited underwater video system (MBUV) (n = 132) methods. The numbers of fish measured with the MBUV in each reef are indicated, and the widths of the boxes within each reef are proportional to those numbers. The x-axis was truncated to avoid loss of detail.

Fig. 1. Mirrored baited underwater video system (MBUV). (a) MBUV settled on bottom for calibration purposes: 1) video signal and remote control, 2) strained cables marked every 200 mm segments, 3) placement of the bait holder, 4) mirrored surface; (b) Camera view of a MBUV deployment showing the naive length of a sea bass Acanthistius patachonicus (NL), the length of its reflected image (LRI), and the reference scales (RS = 200 mm) used for applying the MBUV and Reference scale at the bait level (RSB) procedures. Four fishes (1-4) could be accurately measured in this snapshot; fish #4 could be sized even when its body laid wholly outside of the mirrored area but was partially reflected by it.

Determinants of Reef Fish Assemblages on Tropical Oceanic Islands

ABSTRACT Diversity patterns are determined by biogeographic, energetic, and anthropogenic factors, yet few studies have combined them into a large-scale framework in order to decouple and compare their relative effects on fish faunas. Using an empirical dataset derived from 1527 underwater visual censuses (UVC) at 18 oceanic islands (five different marine provinces), we determined the relative influence of such factors on reef fish species richness, functional dispersion, density and biomass estimated from each UVC unit. Species richness presented low variation but was high at large island sites. High functional dispersion, density, and biomass were found at islands with large local species pool and distance from nearest reef. Primary productivity positively affected fish richness, density and biomass confirming that more productive areas support larger populations, and higher biomass and richness on oceanic islands. Islands densely populated by humans had lower fish species richness and biomass reflecting anthropogenic effects. Species richness, functional dispersion, and biomass were positively related to distance from the mainland. Overall, species richness and fish density were mainly influenced by biogeographical and energetic factors, whereas functional dispersion and biomass were strongly influenced by anthropogenic factors. Our results extend previous hypotheses for different assemblage metrics estimated from empirical data and confirm the negative impact of humans on fish assemblages, highlighting the need for conservation of oceanic islands. Keywords: species richness, functional dispersion, density, fish biomass, biogeographic factors, energetic factors, anthropogenic factors, marine provinces.
