Com o objetivo de verificar a fonte de carbono e a posição trófica das principais espécies de peixe da planície de inundação do rio Paraná, foram analisadas as proporções de isótopos estáveis de carbono (delta13C) e nitrogênio (delta15N) em músculos de peixes amostrados no período de chuvas. Foram analisados indivíduos adultos das espécies Loricariichthys platymetopon, Schizodon borellii, Leporinus lacustris, Auchenipterus osteomystax, Iheringichthys labrosus, Leporinus friderici e Serrasalmus marginatus. e dados foram comparados com os resultados da análise do conteúdo estomacal. Os produtores primários existentes no subsistema Baía foram as plantas C3 (vegetação ripária, macrófitas, perifíton e fitoplâncton) e as plantas C4 (macrófitas). ...
