Introduction: The diversity of fish species in the Amazonian foothills of Ecuador includes moderate-sized species adapted to living in fast flowing, well-oxygenated, stony-bed rivers. These species are still important for subsistence fishing. However, current studies of the ethnoichthyology of indigenous communities settled in the upper watersheds of the main Amazonian tributaries of Ecuador are still incipient. Objective: To characterize the ichthyological richness and the family fishing system of the Kichwa CEPLOA community, in the upper Ecuadorian Amazon. Methods: In 2020 we did a fish an inventory of in the Oglán river, mainly with cast net, and interviewed 18 community members about the family fishing system. Results: We recorded seventeen fish species, with a predominance of Characidae, Loricariidae and Cichlidae, all of them characteristic of well-conserved Amazonian foothill rivers. Local fishermen practice subsistence fishing with cast nets and hooks (mean 1,5kg of fish per catch). The anglers perceive a reduction in the diversity and abundance of fish fauna as well as in their sizes compared to the last decade, possible from the increase in fishing operations and the use of unsustainable catching techniques. Conclusion: The local 17 fish species are typical of well-preserved Amazonian foothill rivers. Local subsistence fishermen reported reduced diversity, abundance, and size of fish, attributed to increased fishing activities and unsustainable catching methods. Internal regulation may reduce the problem.
