Abstract: Abstract:The present study describes aspects of feeding ecology of Dash-dot Tetra Hemigrammus belottii (Characiformes: Characidae) collected in the Urucu River basin in Coari, Amazonas (Brazil), aims to respond the following question: What is the influence of hydrological periods (dry and wet) and spatial distribution in the diet of H. belottii ? The specimens were collected between 2006 and 2009 in seven streams in the Urucu basin using standard capture methods. Their stomachs were removed for diet compositio… Show more

“…brevis indicates not only that these lebiasinids capture allochthonous insects that fall on the water surface, but also reflects the high representation of ants in the soil macrofauna in Central Amazon (Fittkau and Klinge 1973). The importance of these and other resources from adjacent terrestrial ecosystems as food for Amazonian stream fishes ACTA AMAZONICA Resource partitioning and ecomorphological variation in two syntopic species of Lebiasinidae (Characiformes) in an Amazonian stream was reported (Mendonça et al 2012;Gonçalves et al 2013). Terrestrial arthropods that fall into the streams are an important high quality food resource (low C: N ratio) that is directly available to fish (Baxter et al 2005;Small et al 2013).…”

“…Thus, the high consumption of these larvae by G. rondoni and G. coropinae includes both in the detritivory food chain. This strong linkage with the recycled organic matter highlights the importance of these electric-fishes to these streams, since a great portion of Amazonian stream fishes is known to feed predominantly on allochthonous items (Mendonça et al, 2012;Gonçalves et al, 2013;Silva et al, 2016).…”
