Aphyocypris kikuchii

Aphyocypris kikuchii is a species of cyprinid fish. It is endemic to Taiwan. It is a benthopelagic freshwater fish that grows to 8 cm total length.

A.kikuchii has a low dispersal capability, which in turn leads to reduced gene flow between populations and higher genetic differentiation. During the past few decades, A. kikuchii populations have diminished immensely due to habitat degradation. These circumstances have led the species to be assigned with the endangered status.

Named in honor of Yonetaro Kikuchi (1869-1921), collector for the Taipei Museum in Formosa (Taiwan), who collected the type specimen.
