Abstract
In 140 specimens of five carangid species were captured in Playa Las Barrancas and El Cabezo Reef, Veracruz Reef System National Park, Veracruz State, Southern Gulf of Mexico:Caranx crysos (n=51), Caranx hippos (n=18), Chloroscombrus chrysurus (n=28), Oligoplites saurus (n=24) and Trachinotus carolinus (n=19), a total of 44 helminth species were recovered, distributed as follows: 18 digeneans (17 adults, and 1 metacercaria), 12 monogeneans, 9 nematodes (6 adults, and 3 larvae), 4 cestodes (all larvae), and 1 acanthocephalan (juvenile).Parasite of helminths species with the highest prevalence in five communities were Pseudobicotylophora atlantica and Amphipolycotyle chloroscombrus, while species with mean intensity wereHurleytrema catarinensis;and the nematode Hysterothylacium sp., was registered in all five communities. The component community with highest richness and diversity was forC. crysos (S=21, Shannon index H’= 2.19), atinfracommunitylevel highest richness was for T. carolinus (S = 4.5 ± 2.1) and C. hipos (S = 4.1 ± 2.8, while the highest diversity was for C. chrysurus(Brillouin indexH = 1.03 ± 0.32)andC. crysos (Brillouin indexH = 1.01 ± 0.44).The highest Similarity Index of was between the communities ofC. crysosand C. hippos (Jaccard index=60%). Results suggestthat compositions, richness and diversity are similar to other founded marine fishfromtropical and temperate latitudes
