Abstract	O presente estudo teve como objetivo determinar a prevalencia e a intensidade de parasitos nas brânquias, bem como o fator de condicao em matrinxa Brycon amazonicus Spix e Agassiz (1829) cultivados em tres canais de igarape da regiao do Taruma-Mirim, Manaus, Estado do Amazonas. As condicoes sanitarias dos canais de igarape, o manejo dos peixes e os parâmetros fisico-quimicos da agua foram monitorados. De 150 peixes examinados, 25,0% estavam parasitados pelo protozoario Ichthyophthirius multifiliis (18,0%) e por sanguessungas Placobdella sp. (7,0%). A prevalencia de I. multifiliis , nos tres canais de igarape, foi de 22,0%, 18,0% e 14,0%, respectivamente, e a intensidade media foi maior em um dos canais que mantinha peixes em grande densidade populacional. As sanguessugas Placobdella sp. ocorreram somente em um dos canais de igarape. Nao houve variacao sazonal na infeccao de I. multifiliis , mas Placobdella sp. ocorreu somente em janeiro e marco. O fator de condicao dos peixes parasitados foi significativamente (p < 0,001) menor que nos peixes nao-parasitados, porem este nao mostrou correlacao com a intensidade parasitaria.
