A Verdugo tributary draining the Serra do Suído to the Ría de Vigo at Soutomaior. The Oitavén is honest small-river trout water — granite freestone bedrock, pool-riffle structure, partial canopy. Wild brown trout only. Best fished from May into early July in the middle reaches around Fornelos de Montes; useful as a follow-on river when the Verdugo is busy.
