Genetic variation and Phylogeography of Sinibrama Macrops (Teleostei: Cyprinidae) in Qiantang River Basin, China

► We investigated the genetic structure of Sinibrama Macrops in Qiantang River. ► The genetic diversity of Shengzhou population was lowest. ► Fst and genetic distance revealed obvious divergence between Shengzhou and others. ► The demographic history of Shengzhou population was different from others. ► There was no differentiation within populations (except shengzhou) in mainstream.
