Liobagrus kingi is known from the Lake Dianchi basin, in the tributaries and its effluent river Zhangjiu and two tributaries of Jinsha Jiang (Upper Yangtze) in Sichuan and Yunnan Provinces. It was already a rare species in Lake Dianchi basin in the 1960s and it has not been found in the basin, tributaries and springs or in any fish market for many years. It is possible the Zhangjiu and Sichuan populations still exist. The water quality in the two tributaries of Jinsha Jiang is good but the two populations are separated by the construction of hydro power dams. The population in Zhangjiu River is far from the other two, and declining in quality due to polluted water entering from Lake Dianchi. The remaining area of occupancy for this species is about 200 km² and currently it is found in three locations.
2009 Endangered

Population [top]

Population: Since its discovery in 1935 in Jinning County, KIZ have deposited two specimens collected in 1960 and this is the last record of this fish. Even if the species still exists, the population should be very small.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It lives in rivers and streams with flowing water and rocky bottom. It is a small carnivorous fish living at the water bottom.
Systems: Freshwater

Threats [top]

Major Threat(s): The main threats to the species are the sudden explosion of the population of Kunming City and the discharge of domestic and industrial polluted waste water into the lake, seriously polluting the water of the lake and inflow and outflow rivers/streams. In addition, the large-scale reclamation of land from around the lake since the end of the 1950s to the beginning of 1970 destroyed the living and spawning environment of the fish, which is another cause of endangerment.
