Schizothorax grahami, the Kunming snowtrout, is a species of ray-finned fish in the genus Schizothorax . It is endemic to Lake Dianchi, its tributaries and connected springs, in Yunnan Province, China. The species has not been caught in the lake in the past 20 years, but it is present in one tributary drainage basin. The introduction of exotic fish is the main threat to this species. [1]
Dian Lake, also known as Dianchi, Dianchi Lake, Lake Dian and Kunming Lake, is a fault lake located on the Puduhe-Xishan fault in Kunming, Yunnan, China at 24°23′–26°22′ N, 102°10′–103°40′ E. Its nickname is the "Sparkling Pearl Embedded in a Highland". It is the model for the Kunming Lake in Beijing's Summer Palace. Its name is the source of Yunnan's Chinese abbreviation 滇.
Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey. They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) 'to cleave' and thórax (θώραξ) 'breast-plate'. The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. Although they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.

The golden-line barbel is a species of cyprinid fish endemic to Dian Lake and its tributaries in Yunnan, China.
