The present work corresponds to a fish inventory, carried out between August and September 2019, in three sampling sites in the Pintuyacu stream, a tributary of the Itaya River basin, in the Peruvian Amazon. Based on 504 individuals analyzed, 117 species were identified, corresponding to 33 families and 8 orders. The most diverse order was Characiformes (65 species, 55.6%), followed by Siluriformes (31 species, 26.5%). At the Characidae family level, it presents the highest species richness with 24 species (20.5%). The most abundant species were Stethaprion erythrops (13.1%, 66 individuals), Knodus smithi (13.1%, 66 individuals) and Bujurquina peregrinabunda (6.2%, 31 individuals). Species for ornamental and consumer use were recorded. No threatened species were recorded and most were classified as Least Concern (LC), according to IUCN criteria. The present study is the first to present ...

Trichopodus trichopterus (Pallas, 1770) es una especie nativa del sudeste asiático que se introdujo en el Perú como un controlador biológico de los vectores de la malaria y para la ornamentación. Teniendo en cuenta que las especies hospedadoras exóticas pueden co-introducir sus parásitos en ambientes naturales, el presente estudio tiene como objetivo identificar los monogenoideos que parasitan las branquias del gourami de los tres puntos, dando una descripción morfológica de sus especies de parásitos y sus índices parasitológicos. Treinta especímenes de T. trichopterus fueron capturados en julio de 2018 de un estanque natural en Iquitos, Perú. Las muestras se sacrificaron y luego se analizaron en el Laboratorio de Parasitología y Sanidad Acuícola del Instituto de Investigaciones de la Amazonía Peruana (IIAP), Iquitos, Perú. Se encontró al monogenoideo Trianchoratus acle...
