The fish community of Palo Seco Reef, Veracruz, gulf of Mexico and its relationship with the morpho functional groups

The submerged reef banks may play the part of germoplasm reserve, due to their richness and species abundance that contribute to the biomass development in adjacent emergent reefs. The goal of this research was to establish the fish community of Palo Seco Reef, Veracruz, Mexico, and its relationship...

description The submerged reef banks may play the part of germoplasm reserve, due to their richness and species abundance that contribute to the biomass development in adjacent emergent reefs. The goal of this research was to establish the fish community of Palo Seco Reef, Veracruz, Mexico, and its relationship with morpho functional groups of the substrate. One hundred and seventeen visual censuses (63 random and 54 belt-transects) using SCUBA dive equipment were carried out during the Summers of 2013 and 2016 in order to determine the fish community structure (components, richness, abundance, biomass and trophic guilds) and characterize the substrate based on the morpho functional groups (MFG). The relationships between the fish and the substrate were determined by a canonical correspondence analysis (CCA). The ichthyofaune was represented by109 species, including 2 invasive species (Pterois volitans and Neopomacentrus cyanomos), and 3 endemic species of Veracruz (Elacatinus jarocho, Hypoplectrus atlahua and Hypoplectrus castroaguirrei). Halichoeres burekae, Coryphopterus hyalinus and juvenile of Haemulon aurolineatum were the most abundant species, whereas Sphyraena barracuda, Anisotremus virginicus and Megalops atlanticus dominated in biomass. The zooplanctivore guild was the most abundant (83.35 %), in contrast with the herbivorous (1.24 %). The piscivorous fish were the most abundant in biomass (28.89 %), followed by the generalized carnivorous fish (28.22 %). Nine MFG characterized the substrate of Palo Seco Reef. The CCA showed a gradient of MFG and depth which were related to some fish species and to some trophic guilds. The ichthyological community of Palo Seco Reef is similar to the fish communities of other reefs in Veracruz, but its richness and abundance respond to the local environment. The similarity suggests a possible regional connectivity and underlines its importance for conservation.

El objetivo de la presente investigación fue establecer la comunidad de peces del arrecife Palo SecoVeracrz, México, y su relación con los grupos morfofuncionales que caracterizan al sustrato. Se efectuaron 117 censos visuales con equipo de buceo SCUBA (63 censos aleatorios y 54 transectos en banda) durante los veranos de 2013 y 2016, para determinar la estructura de la comunidad de peces (composición, riqueza, abundancia, biomasa y gremios tróficos) y caracterizar el sustrato, usando los grupos morfofuncionales (GMF) a partir de fototransectos. Las relaciones entre los peces y el sustrato se determinaron mediante un análisis de correspondencia canónica (ACC). La ictiofauna de Palo Seco estuvo compuesta por 109 especies, incluyendo 2 invasoras (Pterois volitans y Neopomacentrus cyanomos), y 3 endémicas de Veracruz (Elacatinus jarocho, Hypoplectrus atlahua e Hypoplectrus castroaguirrei). Halichoeres burekae, Coryphopterus hyalinus y los juveniles de Haemulon aurolineatum fueron las especies más abundantes, mientras que, Sphyraena barracuda, Anisotremus virginicus y Megalops atlanticus dominaron en biomasa. El gremio de los zooplanctívoros fue el más abundante (83.35 %) contrastando con la proporción de herbívoros (1.24 %). Los piscívoros presentaron la mayor biomasa (28.89 %), seguidos de los carnívoros generalistas (28.22 %). El sustrato del arrecife se caracterizó por nueve grupos morfofuncionales. En el ACC se observó un gradiente de los GMF y de la profundidad que se relacionaron con algunas especies de peces y con algunos gremios tróficos. La comunidad ictiológica del arrecife Palo Seco en general, se parece a las comunidades de peces de otros arrecifes veracruzanos, pero su riqueza y abundancia responde a las condiciones locales. El parecido sugiere una posible conectividad regional y resalta su importancia para la conservación.  Universidad Autónoma de Tamaulipas 2020-01-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/html text/xml https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/1347 10.29059/cienciauat.v14i2.1347 CienciaUAT; Vol 14 No. 2.
