The study of Electrophorus electricus requires relevance in the Peruvian Amazon due to the use of individuals extracted from their habitats, where the status of their populations is still unknown; this motivated us to study abundance through capture per unit of effort (CPUE) and correlations of morphometric measures in the Anguillal cocha, Itaya river, as well as the analysis of the use of the species for commercial purposes throughout the Itaya basin and the Loreto region. We sectorized the car in four areas where we had 90 sampling units (45 in growing season and 45 in emptying), we applied two methods, of artisan hook and surface spin. We registered 14 individuals and 11 recaptures, where the CPUE was slightly higher in emptying with the hook method. There is a positive correlation between total length and weight (R2 = 0,941). Regarding the use, ornamental export trade of Electrophorus electricus is carried out in various basins of the Loreto region, where the demand for the resource has increased progressively in the last four years. The information generated is a precedent for further studies with a view to sustainable use of the species in Amazonian ecosystems.
