- A multivariate approach to the feeding ecology of the Channel flounder, Syacium micrurum (Pisces, Pleuronectiformes), in Cape Verde, Eastern Atlantic JF Marques CM Teixeira A Pinheiro K Peschke HN Cabral Ciencias de la Tierra flatfish Cape Verde diet diversity Paralichthyidae Syacium micrurum 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. 2009 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48013192002 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1 Vol.35
