Este estudo relata as relações peso–comprimento e fator de condição para o peixe reofílico ameaçado de extinção Ossubtus xinguense Jégu. Esta espécie, endêmica das corredeiras do Rio Xingu, é ameaçada pela construção da terceira maior hidrelétrica do mundo, denominada Belo Monte localizada às proximidades da cidade de Altamira, norte do Brasil. Os espécimes foram coletados na estação seca do rio, entre julho e setembro de 2012. Espécimes machos apresentaram tamanho corporal maior que fêmeas, condição atípica entre os peixes serrasalmídeos, e diferentes relações peso–comprimento foram encontradas entre espécimes juvenis e adultos. Este estudo apresenta as primeiras características biológicas para O. xinguense. 2017-04-19T16:06:50Z 2017-04-19T16:06:50Z 2015-08 Artigo de Periódico ANDRADE, Marcelo Costa ; JESUS, Allan Jamesson Silva de ; GIARRIZZO, Tommaso.
