Gymnocypris przewalskii

Schizopygopsis przewalskii (common name: Przewalskii's naked carp; in Chinese: 青海湖裸鲤; lit. 'Qinghai Lake naked carp') is a species of cyprinid that is endemic to the Lake Qinghai basin in China, where it is the dominant fish species (the other natives are four Triplophysa loaches). S. przewalskii is a planktivore with a main population that migrates from the lake to rivers to spawn and another that lives its entire life in the nearby Ganzi River. The species is listed as endangered on the China Species Red List due to overfishing and habitat loss, which has led to suspension of its commercial fishery four times since 1989. Named in honor of geographer and explorer Nikolai Przhevalsky (also spelled Przewalski and Prjevalsky, 1839–1888), who collected the type species and in whose book about Mongolia Kessler's description appeared.
