The main objective of this work was to report the presence of the pentastomid Sebekia sp. collected from Astronotus oscellatus (Agassiz, 1831) "Oscar" acquired in the Belén market, in Iquitos, Peru during the month of June 2021. The work was carried out through the observation, search, identification, measurement and calculation of the parasitological indices of Sebekia sp. collected from the musculature and stomach of 30 adult specimens of A. ocellatus. A prevalence of 20 %, mean intensity of 1.5 and a mean abundance of 0.3 of Sebekia sp was reported. The morphometric measurements obtained show specimens of Sebekia sp. with a mean body length of 1560.29 µm and 650.78 µm in width. The presence of this parasite in the musculature of A. ocellatus raises an alert to the possibility of its accidental ingestion due to the consumption of its meat in preparations that use raw or undercooked ...

The main objective of this work was to identify taxonomically the parasiticmetazoans present in Astronotus ocellatus "acarahuazú" from the Mercado de Belén, Iquitos – Peru 2022. The work was carried out through the observation, search, identification of parasites in Astronotus ocellatus. The analysis of the fish was carried out in the Laboratory of Parasitology and Aquatic Health of the Research Institute of the Peruvian Amazon (IIAP). In the study, the genus Posthodiplostomum sp., Contracaecum sp., Sebekia sp., and the monogenean species Gussevia asota, Gussevia astronoti and Gussevia rogersi. Likewise, the calculation of the parasitic indices was carried out, resulting in the species Gussevia asota and Gussevia astronoti having the highest parasitic indices with a prevalence of 100% respectively, intensity of 318 and 230 individuals, intensity and average abundance of 7.95 and 5.75...
