Abstract: Foi estudado o hábito alimentar dos peixes da microbacia do Ribeirão Grande, estado de São Paulo (22º 47' 08'' S e 45º 28' 17'' O). O conteúdo estomacal foi analisado usando-se o grau de preferência alimentar, e classificado como autóctone e alóctone, de acordo com a sua origem. As espécies de peixes foram classificadas em três categorias tróficas: herbívoras, espécies que comeram principalmente perifiton; Pareiorhina rudolphi foi a única espécie classificada nesta categoria. Onívoras, espécies que consumiram … Show more

“…However, autochthonous resources dominated the diet of most species. This was also observed in studies performed by GOMIERO (2009) andRONDINELI et al (2011). The low contribution of allochthonous items can be explained by the disruption of riparian vegetation in the studied areas.…”

“…These characteristics were determined for each species from the literature on the regional fish fauna (Casatti and Castro 1998;Luiz et al 1998;Casatti et al 2001;Gibran et al 2001;Castro et al 2004;Gerhard 2005;Oliveira and Bennemann 2005;Ferreira 2007; Gomiero and Braga 2007;Esteves et al 2008;Braga and Gomiero 2009;Rolla et al 2009;Costa and Schulz 2010;Esteves and Alexandre 2011;Rondineli et al 2011). When information was not available for a given species, the characteristics of the genus or family were considered.…”

“…Characidium zebra, an invertivorous, stealth predator species, showed the same afore mentioned pattern. These species, among other from Heptapteridae (Pagotto et al, 2011), Trichomycteridae (Uieda & Pinto, 2011) and Crenuchidae families (Braga & Gomiero, 2009) might be considered specialized, once they are strongly subordinated to specific niches availability in the system. Thereby, changes in environmental conditions that alter specific niches may deeply affect those species (Villéger et al, 2010), as observed for the simplified reach.…”
