" Girardinichthys multiradiatus is endemic to Mexico and is in the vulnerable category. Their feeding habits were determined in La Goleta reservoir, analyzing the stomach content of 600 individuals by numeric, frequency and volumetric methods. We observed that G. multiradiatus uses a great variety of foods. The analysis of frequency shows that the alga Fragilaria has the biggest presence in the four stations. The volumetric analysis showed, in fishes of 2.0-3.5 cm, that Chironomidae and Diaptomidae stand out; while in fishes of 3.6-5.0 cm were Diaptomidae, Trichocorixella mexicana, Fragilaria and Oedogonium, indicating a more varied use of feeding resources. We conclude that it is an omnivorous fish that consumes zooplankton, zoobenthos and fitoplankton "
