Piccolo astratto: “Of the 33 preys found in the stomachs of M. polyacanthus, 21 were fish and 12 were invertebrates. Characiformes (16) and Perciformes (3) represented 76.1% FN and 14.2% FN of the preys respectively. Among the Characiformes, Characidae was the most commonly recorded prey family (62.5% FN; n = 10), followed by Lebiasinidae (37.5% FN; n = 6). Both families were represented by three species each: Hemigrammus analis, H.belottii and Hemigrammus sp. (Characidae); and Nannostomus eques, N. unifasciatus and N. trifasciatus(Lebiasinidae). Perciformes were not identified to species level due to the advanced state of digestion of these preys (Table 1).”
“Invertebrates were represented by 12 specimens of crustaceans (Decapoda and Conchostraca) and insect remains (Coleoptera, Hymenoptera and larvae of Ephemeroptera and Odonata, Table 1).”
