Estrutura trófica da ictiofauna em um reservatório do semiárido brasileiro

Abstract: ABSTRACT. Trophic structure of the ichthyofauna in a Brazilian semiarid reservoir. The establishment of the trophic structure of fi sh provides information on species autoecology and their role in the ecosystem, in addition to supporting conservation and management practices for sustainable use of native species. In the semiarid region of Rio Grande do Norte there are few studies of the natural diet of fi sh. In this context, this study aimed to characterize the trophic structure of the fi sh assemblage of the… Show more

“…With the possibility to understand the ecology of the species and their role in the ecosystem and to identify the factors that determine the pattern of fish feeding throughout their life cycle (Oliveira et al 2016b). In Brazil, in recent decades there has been an increase in studies related to natural fish feeding, with a higher concentration for the species of major commercial interest, mainly of rivers and lakes in the North, South and Southeast regions of the country.…”

“…The Steindachnerina notonota (Miranda Ribeiro, 1937) in the reservoirs of Riacho da Cruz (Teixeira and Gurgel 2004) and Pau dos Ferros (Oliveira et al 2016a) was listed. Hypostomus pusarum (Starks, 1913), in the Marechal Dutra reservoir (Pessoa et al 2013) and in Santa Cruz reservoir (Oliveira et al 2016b). Prochilodus brevis (Steindachner, 1875) and Loricariichthys derbyi (Fowler, 1915) in the Pau dos Ferros reservoir (Oliveira et al 2016a).…”

“…Santos (2005) classificou a espécie como onívora, mas com uma proporção equilibrada de itens de origem animal e vegetal em sua dieta, em trechos de dois rios na Bahia. Com relação ao estado do Rio Grande do Norte, estudos referentes à espécie são escassos, com destaque para os trabalhos realizados no rio Piranhas-Açu (Alto do Rodrigues, São Rafael e Açu), e açude Corredor (Martins) que a classificaram como insetívora (Gurgel et al, 2002); a espécie também apresentou a dieta insetívora no estudo realizado no reservatório de Santa Cruz por Oliveira et al (2016b). Nos reservatórios objetos deste estudo, embora exista a presença de insetos na dieta, estes não estiveram em proporções relevantes para se considerar a insetivoria como tendência.…”
