“…The three studied species are migratory and their genera are widespread in South American basins (Fernandez et al, 2004;Alves, 2007). In the study site, they are representative in samplings: Pimelodus maculatus corresponded to 35.4% of fish captured in the tailrace, while Prochilodus costatus accounted for 16.5% and Leporinus reinhardti accounted for 15.3% (Andrade et al, 2016). This high presence in the downstream areas of the HPP is one factor linked to the fish-kill events of those studied species.…”

“…O aumento de Qd pode ser interpretado pela comunidade de peixes como pulsos de cheia no rio. Loures, Pompeu (2012) relataram que a vazão defluente da UHE Três Marias, no rio São Francisco, foi um dos principais fatores que explicaram a variação da abundância de peixes no canal de fuga dessa usina, sendo o mesmo padrão observado especificamente para P. maculatus (Andrade et al, 2017). Para EM, como Qd compôs a melhor solução para resposta da comunidade de peixes às variáveis ambientais, e P. maculatus foi a espécie mais abundante da comunidade, é possível atestar a influência da variação de Qd nessa espécie.…”
