The research carried out in the lower basin of the Nanay River, aims to know the taxonomic composition and characterization of the fishing for human consumption, this will allow having an updated taxonomic list, which serves as the basis for studies related to fishing activity. Likewise, the knowledge of the consumer fishery is an important part as an input to develop measures and management plans for the conservation of fishery resources. For the sampling methodology, fishing nets, cast net, trawl net, and hooks were used to capture the fish to diversify the fishery. Four field samplings were carried out in 2020, coinciding with the hydrological period of emptying (2) and rising (2), in nine sampling stations; Surveys were applied to the fishermen based on direct interviews to analyze the variables and indicators of the fishery. A total of 2,399 specimens were collected, distributed in 145 species, 109 genera, 38 families, and 9 orders. The Characiformes was the most diverse (81 species), followed by the Siluriformes (36 species), both make up 81% of the total registered species. In addition, the diversity indices analyzed, in all the evaluated environments registered a high Shannon Wiener value, which fluctuated between 3.01-4.13 bits / ind., presenting slightly high equity values with values between 0.93 and 0, 97. Fishing is for self-consumption, with the net, hook, and arrow being the main gear in fishing; the average daily fish consumption per family is 2 to 3 kg.
