The feeding ecology of the Channel flounder, Syacium micrurum, from Cape Verde was studied in November 2003 and April 2004, using frequency of occurrence and percentage by number indices, as well as multivariate analyses. Overall, S. micrurum exhibited a generalist feeding strategy with a relatively broad niche width. Analyses indicated Crustacea (especially Brachyura) and Polychaeta as the dominant prey items, although other items, such as Foraminifera, Caridae or Actinopterigii, were preyed on more often or in larger quantities, depending on the sampling date. An ontogenetic shift in diet was also observed with smallsized individuals mostly consuming Crustacea, whereas medium- or large-sized specimens fed on Actinopterigii more often. Diet composition appeared to be more related to differences in benthic assemblages between sampling dates due to the geographical characteristics of Cabo Verde. Results presented here support the need for further studies in the area, mainly those considering the composition and seasonal variation of invertebrate communities, to improve the knowledge of the trophic structure of commercially important species within this area.  En noviembre de 2003 y abril de 2004 se estudio la ecologia alimenticia del lenguado anillado, Syacium micrurum, de Cabo Verde, usando los indices de frecuencia de ocurrencia y porcentaje por numero, asi como un analisis multivariado. En general, S. micrurum mostro una estrategia de alimentacion generalista y relativamente diversificada. Los analisis indicaron que entre sus presas predominaron los crustaceos (particularmente braquiuros) y poliquetos, aunque otros grupos como los Foraminifera, Caridae o Actinopterigii aparecen con mayor frecuencia o en mayor cantidad, dependiendo de la epoca de muestreo. Tambien se observo un cambio ontogenico en la dieta: los individuos mas pequenos consumieron sobre todo crustaceos, mientras que los medianos y grandes se alimentaron con mayor frecuencia de actinopterigios. La composicion de la dieta parece estar mas relacionada con la composicion especifica de la comunidad bentonica en las epocas de muestreo, debida a su vez a las caracteristicas geograficas de Cabo Verde. Los resultados presentados en este trabajo apoyan la necesidad de profundizar en este tipo de estudios, particularmente considerando la composicion de las comunidades de invertebrados y su variacion estacional, de manera que se profundice en el conocimiento de la estructura trofica de las especies de interes comercial que habitan en Cabo Verde.
