“…The depth of this habitat varied between 2.5 and 4.5 m, and its structural complexity was high and presented transparent waters (Figure3G and H). These habitats were similar to those determined in the shallow parts of platform-type reefs[22,23].…”

The biological knowledge of the reef communities of southern Veracruz is fundamental, because, according to the Mexican National Commission for the Knowledge and Use of Biodiversity, they are part of a priority marine zone. This paper describes the ichthyological components of the southern Veracruz fringing reefs, including information on abundance and distribution. 146 random visual censuses were conducted in 5 habitats characterized by the dominant benthic groups and environmental features (structural complexity, transparency, and depth). In each census, fish species were identified and their abundance estimated using 6 ordinal categories. Subsequently, the similarity of the ichthyologic communities with the Jaccard Index was determined. The reef formations of southern Veracruz include 91 fish species, 58 genera, and 31 families. According to their relative abundance, 25 % of the fish species were catalogued as rare, 25 % as uncommon, 23.9 % as occasional, and 22.7 % as common or abundant. The most abundant fish species were: Stegastes adustus, Halichoeres bivittatus, Thalassoma bifasciatum, Bodianus rufus, and Ophioblennius maclurei while, the families: Epinephelidae, Gobiidae, and Scaridae showed a scarce richness and abundance. The benthic attributes (coral cover) and environmental features of habitats were related to the richness, components, and relative abundance of fishes.

“…Zonation of the platform-type reefs (crest, lagoon, windward and leeward slopes) is defined by the benthic components [21,[23][24][25][26] resulting from wave exposure, ocean currents, suspended sediments, and turbidity [27,28]. Coral coverage of these reefs is 15 to 25% [21,26]. Veracruz's submerged banks have an irregular to oval or semicircular shape, with a depth ranging from 1 to 40 m [19].…”

The state on knowledge of fish communities associated with coral reefs of the southern Gulf of Mexico (Veracruz, Campeche bank), and eastern Yucatan on the Caribbean is reviewed, in addition to a description of the main fisheries of the area. The review includes coral reef fish of Veracruz, the Campeche Bank, and reefs running along the Caribbean coast up to the border with Belize. Data recorded suggest that the heterogeneity of different levels (region, reef and reef zone) may be responsible for a larger number of niches available, promoting higher specific diversity that is more evident in the Caribbean reefs. The environmental conditions create patterns of differential abundance among the three zones. The main regional fisheries include more than 60 species and the current yield suggests a 30% reduction compared to catch volumes recorded a few years ago. The changes in coral coverage and the fishing pressure over coral reefs have exerted effects on species of fishing importance.

“…Since these enhance marine diatom's growth and other essential food supplies, it could have prompted the presence of H. viridiaurantia in Playa las Islitas and its absence in the rest of Matanchén Bay. In addition, other conditions such as the sediment input from the mouth of the San Cristobal River, sunlight, temperature, and nutrient availability may have promoted algal growth and, consequently, sea cucumber species to thrive (Huettel et al 2014, González-Gándara et al 2015. Furthermore, the presence of sandy zones between coralline and rocky areas favors the occurrence of irregular echinoids and holothuroids, which is related to the feeding habits of both groups, as they depend upon filtration methods or sand foraging to acquire their food (González-Gándara et al 2015).…”

Sea cucumbers (holothuroids) play a major role in coastal environments; their detritivore conduct favors oxygen penetration in the sediments and the disposal of pathogens on the sea floor. This study determined holothuroid diversity in the rocky intertidal zone of Matanchén Bay, Mexico. Sampling campaigns were carried out in January, March, May, and July 2018. Linear transects (10 m length and 1 m width) perpendicular to the coastline in rocky areas (0-3 m depth) were established, where the density (ind m-2) and proportion (%) of sea cucumbers were estimated. Organisms were photographed, examined live, and preserved in 70% alcohol for subsequent identification utilizing ossicle characterization. Our results show the presence of four sea cucumber species: Holothuria (Halodeima) inornata Semper, 1868, Holothuria (Selenkothuria) lubrica Selenka, 1867, Holothuria (Selenkothuria) portovallartensis Caso, 1954, and Holothuria (Mertensiothuria) viridiaurantia Borrero-Pérez & Vanegas-González, 2019. The average density per species was 0.208, 0.108, 0.017, and 0.025 ind m-2) and proportion (%) of sea cucumbers were estimated. Organisms were photographed, examined live, and , respectively; each species' proportion was 58.1, 30.2, 4.7, and 7.0%, respectively. Due to the above values, we found that the number and spatial distribution of sea cucumber species vary in Matanchén Bay.
