A total of 86 Triportheus angulatus specimens were collected during four expeditions
during the months of May, July and September, November 2015, in the Catalão
floodplain lake located near Manaus, Amazonas. A total of 1.106 individuals
corresponding to 14 parasites of tree taxa Monogenoidea, Nematoda and Copepoda. In
this work, T. angulatus is host type for eight species of Monogenoidea: Anacanthorus
acuminatus, A. chaunophallus, A. chelophorus, A. euryphallus, A. lygophallus, A.
pithophalus, Ancistrohaptor falciferum, A. falcunculum, and one of Nematoda,
Procamallanus (Spirocamallanus) inopinatus. And new definitive host for three species
of Monogenoidea, Jainus sp. n. 1, Monogenoidea gen. nov. 1 and Rhinoxenus
anaclaudiae and one of Copepoda Ergasilus triangularis. Triportheus angulatus is a
new paratenic host for Anisakis sp. The most parasitized organ was the gills with the
Monogenoidea group, with greater richness and abundance of species. The three
secondary species were Jainus sp n 1, Monogenoidea gen nov 1 and A. chellophorus,
respectively. The other 11 species were satellites, and there was no record of central
species in T. angulatus. Triportheus angulatus is an opportunistic omnivorous fish and
had a mean intensity of the parasitic infracommunity of endoparasites (IM = 2.55 ±
0.18) lower than that of ectoparasites (IM = 12.29 ± 2.16). The correlations between
parasite intensity and standard host length were strongly positive, as well as the average
abundance between the high and low water periods were also significant through the
Wilcoxcon test. |
