Piaractus brachypomus (Pacú) is the main native fish species cultivated in Peru and holds great potential for growth aquaculture from Peruvian Amazon. Between October 2021 January 2022 two producing farms Amazon region of San Martín Peru, P. individuals were examined parasite evaluation. A total 6366 monogeneans isolated gills 30 fish, revealing a prevalence 100%, with an abundance mean intensity 212 parasites per fish. Monogeneans morphologically identified as Mymarothecium viatorum Anacanthorus penilabiatus. The genetic divergence 28S rDNA gene found among A. penilabiatus sequences was 0.1% spp. it ranged 0.9% to 7.5%. M. 0.3%. These finding represents first molecular data using these monogeneans. new obtained will contribute future studies on phylogenetic relationships dactylogyrids. However, further research broader range host-parasite samples additional markers needed clarify provide stronger support positions.
