“…However, the knowledge on the assemblage structure of reef fishes is scarce, with few studies that just averaged abundances for the whole reef system, which recorded Chromis multilineata, Halichoeres burekae, Coryphopterus personatus, Haemulon aurolineatum, Stegastes adustus, and Abudefduf saxatilis as the most abundant species. Additionally, higher fish densities have been reported for the reefs of the northern group, for the 10-15 m range depth, and for the 2009 year in the 2006-2014 period (González-Gándara & Chávez, 2020;Olán-González et al, 2020;Pérez-España et al, 2015;Rangel-Ávalos et al, 2008). However, none of these studies addressed for differences in the reef fish assemblage structure among reefs, nor they found a relationship with any ecological or environmental factor.…”
