Abstract

We recorded the parasitic fauna of Hoplias malabaricus in a Neotropical River from southeastern Bra-zil, the Jacare-Pepira River, in the Tiete-Batalha River Basin. The objective of this study was to inven-tory the composition of the parasitic fauna of H. malabaricus collected, through ecological and bio-diversity approaches. A total of 30 specimens of H. malabaricus were collected in 2018 using fishing nets. Parasites were prevalent in 96.6% of the hosts, with 710 parasites specimens collected, divi-ded into 22 species from 4 different taxa (i.e., Monogenea, Digenea, Nematoda, and Acanthocephala). This was the first survey about the parasitic fauna of H. malabaricus in this river, where three spe-cies are new records for this host (i.e., Gussevia sp. 1, Gussevia sp. 2, and Raphidascaris sp.). All species found are new records for the Jacare-Pepira River, which together with all the data obtained in the study, collaborates to increase knowledge and understanding of the global fish parasite biodiversity.
