Spinitectus asperus and Klossinemella iheringi , intestinal nematodes of Prochilodus lineatus (Pisces, Prochilodontidae) from the alluvial plain of the Middle Paraná River, Argentina.

Prochilodus lineatus has been considered an ecosystem engineer in the Neotropics given its influence on important ecosystem processes, and it is therefore relevant to understand their inter-specific relationships. The association of P. lineatus with parasitic helminths was studied in two isolated shallow lakes of the alluvial plain of the Middle Paraná River.

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.
