Identifying the taxa of the endoparasitic fauna as well as their frequency, intensity, abundance, and organs affected was the aim of the current study in Plagioscion squamosissimus (croaker) from four main markets in the city of Iquitos - Perú. A total of 60 specimens of the species were examined through observation, search and direct identification. The eyes, skin, muscle and viscera were studied in search of endoparasites. Larvae of the genera belonging to nematoda were identified: Hysterothylacium sp. and Spiroxys sp. in eyes, Contracaecum sp. and Procamallanus (Spirocamallanus) inopinatus (adult) in intestine, Anisakis Type I larvae and Pseudoterranova sp. in coelomic cavity and intestine, and one species of acanthocephala: Rhadinorhynchus plagioscionis in pyloric caeca. Likewise, the calculation of the parasitic indices (mean frequency, intensity, intensity and abundance) and the correlation of the size and weight of the fish with the parasitic abundance were carried out. It is concluded that the endoparasites present in Plagioscion squamosissimus are composed mostly of nematode species, with a high diversity of species in specimens from the natural environment.
