The objective of this study was to identify the ectoparasites of Colossoma macropomum juveniles, which are cultivated in four fish farming centers (CP1, CP2, CP3 and CP4), on the axis of the Iquitos-Nauta highway. For this, during the months of March to May 2019, a total of 84 juveniles of Colossoma macropomum were collected, being transferred to the facilities of the NGO's Amazon Research Center for Ornamental Fishes. The fish were sacrificed and samples of skin, eyes, fins, nostrils, oral cavity and gills were analyzed. Likewise, the water quality of the culture ponds was recorded at the time of the fish collection. The parasites were identified using specific taxonomic keys for each class of parasite and the parasitic indices, prevalence, abundance, mean intensity and mean abundance were determined. For the relationship between the weight and length of the fish, the physical-chemical parameters (temperature, pH, dissolved oxygen, carbon dioxide and ammonium) of the water with the abundance of the ectoparasites, the Spearman correlation coefficient (rs) was used. Three monogeneans were identified, two at the species level (Anacanthorus spathulatus and Notozothecium janauchensis) and one at the genus level (Mymarotecium sp.), Located in gills; Likewise, a protozoan, Piscinoodinium pillulare, located on the skin, fins and gills, was identified. Monogeneans were present in the four fish farming centers, with the exception of the protozoan, which was present in CP4. The parasitic indices were different in each fish farm. There was no relationship between the weight and length of the fish with the abundance of ectoparasites. There was no relationship of the physical-chemical parameters of the water with the abundance of the ectoparasites in the fish farms CP1, CP2 and CP3, with the exception of CP4. Monogeneous ectoparasites are frequent in the culture of Colossoma macropomum juveniles.
