El objetivo de esta investigación es determinar la dieta y cambios tróficas durante las temporadas de aguas altas y bajas de la ictiofauna predominante en un lago de várzea en la Amazonia colombiana. Las colectas se realizaron durante aguas altas y bajas en 2010, utilizando redes agalleras, red de arrastre y jamas. Se analizaron los contenidos estomacales de 875 ejemplares de 66 especies (30 para aguas altas y 48 aguas bajas); a través del Índice de Bray-Curtis se determinó la similitud entre las dietas de las especies; se utilizó el Índice de Levin para determinar la amplitud del nicho trófico. Hubo cambios en la composición de los gremios tróficos en ambas temporadas (X2=323.95, P=<0.001). Se hallaron seis gremios tróficos para la temporada de aguas bajas y cinco durante las aguas altas. Durante las dos temporadas se registraron cambios en la composición de la dieta que parecen corresponder a la oferta de recursos. Se recomienda en futuras investigaciones incrementar el número de muestras de los contenidos estomacales y ampliar el muestreo a las otras temporadas del ciclo hidrológico para determinar la variación trófica con mayor precisión. 

The aim of this research is to establish the diet and trophic changes of the predominant icthyofauna in a varzea lake of the Colombian Amazon, during high water and low water seasons. The collections were made during high water and low water seasons in 2010, employing gill nets, bottom trawl net and landing nets. Stomach contents of 875 specimens from 66 species (30 for high water and 48 for low water) were analyzed; species diet similarity was determined through the Bray-Curtis Index; the trophic niche extent was determined using Levin’s Index. There were changes in the compositions of the trophic guilds in both seasons (X2=323.95, P=<0.001). Six trophic guilds for high water season and five for low water season were found. Changes in diet composition were recorded in both seasons, which appear to correspond to resource offer. For future research, it is recommended to increase the number of samples for stomach contents and to widen the sampling to the other season of the hydrological cycle in order to determine with greater precision the trophic variation.
