Abstract: This study provides the first investigation on acquisition of parasites in invasive O. niloticus by parasite species of native Cichlidae from the Igarapé Fortaleza basin, Northern Brazil. There were examined 576 specimens of 16 species of native cichlids and invasive O. niloticus collected in the main channel and the floodplain area of this tributary of Amazon River. The invasive O. niloticus was poorly parasitized having only Ichthyophthirius multifiliis, Trichodina centrostrigeata, Paratrichodina africana, T… Show more

“…Gorytocephalus spectabilis only parasitized T. coriaceus, and at low infection levels, which were similar to those reported for Aquidens tetramerus Heckel, 1840; Heros efasciatus Heckel, 1840; Chaetobranchus flavescens Heckel, 1840; and Satanoperca jurupari Heckel, 1840 -all these hosts were also from the ecosystem of this study (BITTENCOURT et al, 2014b;TAVARES-DIAS et al, 2014). Although congeneric host species have similar biological and behavioral characteristics and are therefore potential hosts for parasitic fauna that is also similar, closely related species may also exhibit divergent characteristics that allow them to coexist, such as in relation to some trophic traits (GUIDELLI et al, 2009).…”

“…In these two hosts in the Amazon region, the dominant species were T. tetramerii and Trichodina nobilis, followed by I. multifiliis. These protozoans are typical of lentic-eutrophized environments like the hydrographic basin of this study , 2014BITTENCOURT et al, 2014b). In addition, in T. coriaceus and T. galeatus, the greatest richness of parasites was in species of helminths, with predominance of endoparasites of relatively high prevalence and low abundance, but only two endoparasites were found in larval stage (Contracaecum sp.…”

“…Characteristics of the habitat may facilitate the transmission and establishment of fish parasites (MOREIRA et al, 2009;COSTA-PEREIRA et al, 2014;BITTENCOURT et al, 2014;OLIVEIRA et al, 2016). The abundance and diversity of the invertebrate fauna are also key components in the formation of a parasite community in fish populations (MOREIRA et al, 2009;MORLEY, 2012;TAVARES-DIAS et al, 2015).…”

“…Consequently, this increases the possibility of the fish finding different infective stages of the parasite species in the environment. (BITTENCOURT et al, 2014). However, as there are few reports on the occurrence of E. paranensis in fish, little is known about its biology and life cycle.…”
