The granulometric composition and the most important inorganic componente of sediments in the stomach of two mullet species (Mugil cephalus and Mugil curema) were sampled m Tamiahua lagoon, Veracruz, Mexico. M. cephalus is characterized by the presence of fine sand to medium silt, with diameters of 125 to 15 m with preference for fine sand of 63 m. M. curema presented an interval of fine sand from 125 m to coarser silt of 32 m of thickness with preference for the latter. Presence of fine particles probably is related with diatom abundance in the stomach of both species: diatoms are the main nutritional source. The granulometric differences of the two species suggest competitive exclusion.
Se realizaron muestreos mensuales de las descargas comerciales de Mugil cephalus y Mugil curema en la laguna de Tamiahua, Veracruz. Se revisaron un total de 160 individuos de abril de 1991 a marzo de 1992. El sedimento y grupos taxonómicos presentes en el contenido estomacal fueron extraídos de la porción cardíaca del estómago. Las muestras izb sedimento se analizaron por el método de "frotis" en lámina delgada (Rothwell 1989), el tamaño y composición de sedimento se cuantificaron por el método de conteo de grano.
