Species of Monogenoidea from fish species used in aquaculture in the Peruvian Amazonia

In the present study it is presented a list of species of Monogenoidea with their fish-hosts used in aquaculture in the Peruvian Amazonia. Fish species were obtained from April 2018 to April 2022 from different artificial fish ponds located in “Centro de Investigaciones Fernando Alcántara Bocanegra” (CIFAB) of the “Instituto de Investigaciones de la Amazonía Peruana (IIAP) in Loreto-Peru and from fish ponds of the “Centro de Investigación Carlos Miguel Castañeda Ruiz” from IIAP, San Martín- Peru. A total list of fourty-eight species is presenting in the present study: one species from Arapaima gigas (Schinz); four species from Colossoma macropomum (Cuvier); five species from Myloplus schomburgkii (Jardine); two species from Piaractus brachypomus (Cuvier); 19 species from Pygocentrus natterei (Kner); one species from Prochilodus nigricans (Spix & Agassiz); five species from Brycon amazonicus (Spix & Agassiz); one species from Chaetobranchus flavescens; three species from Astronotus ocellatus (Agassiz); two species from Cichla monoculus (Agassiz); four species from Pterigoplichthys pardalis (Castelnau); three species from Calophysus macropterus (Lichtenstein); and three species from Pseudoplatystoma punctifer (Castelnau). •First check list of monogenoids from fishes from aquaculture.•First reports of some species of Monogenoidea in the Peruvian Amazonia.•This study constitutes a base line to sanitary investigations.•The results contribute to improve aquaculture activities in the Peruvian Amazon.
