Gill parasites of Prochilodus lineatus (Valenciennes, 1836) (Pisces; Curimatidae; Prochilodontinae) in the Middle Paraná System (Argentina)

We studied gill parasites of Prochilodus lineatus in the San Javier River, which is connected to the Middle Paraná System (Santa Fe, Argentina). In 25 specimens, the parasite prevalence in branchial organs was 92% and the average intensity was 8.3 parasites/infested fish. The parasite community showed no dominance of any taxon, but the family Dactylogyridae represented 60% of the community. We found a significant association between Tereancistrum curimba and Dactylogyridae specimens. The prevalence of the parasites T. toksonum and T. curimba was higher than what has been recorded in the floodplain of the Upper Paraná River, Brazil, demonstrating that the geographic distribution of parasites belonging to Tereancistrum genus is thus expandeing.
