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.
