Cyprinus yunnanensis

Unknown

Overview

Cyprinus yunnanensis is a critically endangered species of cyprinid fish in the genus Cyprinus from Qilu Lake in Yunnan, China. Despite surveys of the lake it has not been seen since the 1970s and it is possibly extinct. It reaches up to about 20 cm (8 in) in length.

Cyprinus yunnanensis faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development around Yunnan's freshwater systems. Introduction of non-native fish species has created intense competition for resources and spawning sites. Water pollution from industrial activities and dam construction has further fragmented the species' already limited range in southwestern China's highland lakes and rivers.
