The objective of this research is to determine the effect of the riparian forest on the fish community of the Tumbaro, Naranjillo, and Mayo rivers in the Native Community of Shampuyacu, Awajun, Peru. Sampling was carried out at 14 points in the three rivers located in the Native Community. The collection of fish involved the use of passive and active fishing gear. The riparian forest was classified utilizing satellite images into three categories: primary forest, secondary forest, and agricultural cultivation, and finally eight physicochemical parameters were measured. A total of 1,198 fishdistributed in 12 families and 27 species were collected. The Characiformes represented 57.3% of the total, followed by the Siluriformes (32.7%) and Perciformes (10%).
