This study determined the trophic level of the ichthyofauna in La Goleta reservoir, located in the State of Mexico. A sampling was carried out in the spring of 2007 in which the following water parameters were recorded: temperature, depth, transparency, turbidity, dissolved oxygen, conductivity, pH, hardness, and alkalinity. In addition, fish were caught using a drag net. Stomach content analysis was performed using the numerical and volumetric method. The fish caught belong to three species: Menidia jordani, which is considered a generalist zooplanktofagous species, Cyprinus carpio, a highly generalist omnivore, and Carassius auratus, which is a generalist herbivore.
