Caridina yilong is a species of freshwater shrimp in the family Atyidae. C. yilong was described from Lake Yilong (Yilong Hu) in Yunnan, China, and was believed to be endemic to the margins of the lake among fringing vegetation. Only the type series has ever been collected, and the type locality of Lake Yilong has since dried up for extended periods of time due to the abstraction of water (notably in 1984, one year after their collection, a twenty-day period of complete dryness was recorded). Organic pollution caused by sedimentation along with agricultural and industrial pollution has caused this species to be assessed as Critically Endangered by the IUCN, with the caveat possibly extinct. [1] In addition, two species of fish, Anabarilius macrolepis and Cyprinus yilongensis , that also were endemic to the lake are now extinct. [3] [4]
Cyprinus is the genus of typical carps in family Cyprinidae. Most species in the genus are of East Asia origin with only the common carp in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. Cyprinus are closely related to some more barb-like genera, such as Cyclocheilichthys and Barbonymus (tinfoils). The crucian carps (Carassius) of western Eurasia, which include the goldfish, are apparently not as closely related.
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.
Yilong Lake is a large freshwater lake located in Shiping County, Honghe Prefecture, Yunnan province, southwestern China. The lake has a surface area of approximately 32 square kilometres (12 sq mi) and is particularly notable for its scenery, including the colorful lotus flowers that bloom on its surface. It is located about 2 kilometres (1.2 mi) east of the county seat. The people who live in the vicinity of the lake are largely of the Yi ethnic group. As of the spring of 2013 a severe drought had resulted in substantial lowering of the water level.
Anabarilius is a genus of ray-finned fish in the family Cyprinidae, most of them only occurring in the area of China. Many of the species have very restricted geographic range and have been negatively impacted by introduced species, fishing, and habitat degradation; the IUCN Red List includes five Anabarilius species that are either endangered or critically endangered and one species that is considered extinct.
Cyprinus yilongensis is an extinct species of ray-finned fish in the family Cyprinidae. It was found only in Yilong Lake, Yunnan, China. It was last seen before 1981, when the lake was drained for 20 days, presumably causing the species' extermination.
Fuxian Lake is a body of water in Yunnan Province, China. It stretches through Chengjiang, Jiangchuan and Huaning Counties, spanning an area of 212 square kilometers. It is the third-largest lake in Yunnan, after Dian Lake and Erhai Lake, and the deepest, at 155 meters. It is the third-deepest fresh water lake in China, after Tianchi and Kanas Lake.
Anabarilius alburnops is a species of ray-finned fish in the genus Anabarilius. It is only known from Dian Lake and Songhuaba Reservoir, both in Kunming, Yunnan. It can reach sizes above 31 cm (12 in) SL.
Anabarilius andersoni is a species of cyprinid fish that is endemic to China. It is a pelagic species only known from Xingyun Lake in Yunnan, and its population is severely impacted by domestic pollution and overfishing.
Anabarilius macrolepis is an extinct species of ray-finned fish in the family Cyprinidae that was endemic to Yilong Lake in Yunnan, China. It is believed that it became extinct when Yilong Lake dried up in 1981, as a result of water abstraction for agriculture. The species was not observed in 1983–84, and was declared extinct in 2011.
Anabarilius maculatus is a species of cyprinid fish in the family Xenocyprididae. It is endemic to the Nan Pan Jiang basin in Yunnan, southern China. It is threatened by invasive non-native species, domestic and urban waste water, agricultural pollution and dams. The species have not been studied well, therefore its ranked as Data Deficient. It grows to 13.9 cm (5.5 in) standard length.
Anabarilius xundianensis is a species of cyprinid fish in the family Xenocyprididae. It is endemic to Yunnan (China). It is known from Qingshui Lake in the eponymous Xundian County, on the Jinsha River. The exact threats are unknown but it may be fished for food and sensitive to pollution.
Cyprinus barbatus is a species of ray-finned fish in the genus Cyprinus. It is endemic to Lake Erhai in Dali, Yunnan, China. It is negatively impacted by agricultural and domestic pollution and introduced species. The IUCN considers it as critically endangered and possibly extinct, but records as recent as the 2000s (decade) show that it likely does survive.
Caridina dennerli is a small species of freshwater shrimp from Sulawesi (Indonesia) that grows up to 2.5 centimetres (1.0 in) in length. It takes its name from the German company Dennerle, which supported the expedition that led to the scientific description of the species. It is popularly known as the cardinal shrimp or Sulawesi shrimp in the aquarium trade.
Caridina woltereckae, or Sulawesi harlequin shrimp as it is commonly known in the aquarium hobby, is a freshwater shrimp from Sulawesi, Indonesia. It is endemic to Lake Towuti. It resembles the smaller and less contrastingly coloured Caridina spongicola, which is endemic to the same lake.
Caridina striata is a freshwater shrimp from Sulawesi. It is endemic to Lake Poso and Lake Towuti. Common names in the aquarium hobby are red line shrimp and red stripe shrimp. It is commonly found on rocky substrates.
Caridina ensifera is a freshwater shrimp from Sulawesi. It is one of the 11 species of Caridina endemic to Lake Poso. It lives on a variety of substrates, including wood, rocks, sand and macrophytes, but is also found in pelagic swarms. It is suspected to only live in shallow water.
Caridina caerulea is a freshwater shrimp from Sulawesi. It is one of 11 species in the genus Caridina that is endemic to Lake Poso. It lives on a variety of substrates, including wood, rocks, sand and macrophytes. It is suspected only to live in shallow water.
Caridina apodosis is a species of freshwater shrimp in the family Atyidae endemic to a mountain stream near the village of Tai Tong, China. Caridina apodosis is known from only the type series, collected in 1994. The exact type locality is unknown, and may be completely overtaken by urban sprawl. Caridina apodosis is assessed as Critically Endangered by the IUCN under criterion B1ab(iii)+2ab(iii) with the caveat 'possibly extinct'. C. apodosis is threatened by extensive water pollution as a result of urbanization, and the type locality may be unsuitable for inhabitance.
Caridina linduensis is a species of freshwater shrimp in the family Atyidae, endemic to Lake Lindu and its effluent stream in Sulawesi. It was known only from the type series, collected in 1904, and was recorded again in 2011 in a survey around Lake Lindu and is found in shallow littoral habitats of leaf litter, macrophytes, and dead wood. In the effluent stream it is found on soft substrates and slow flowing water, and is less common in the lake itself. The type locality of Lake Lindu was designated as a Recreation Park in 1978, and is part of the larger Lore Lindu National Park and UNESCO Biosphere Reserve. It is listed under IUCN criterion B1ab(iii,v) as Critically Endangered due to threats from introduced species of fish, land conversion to agriculture, logging, and shore disturbance caused by the grazing of water buffalo. Surveys are required to find the full distribution of C. linduensis, primarily its habitat in the effluent stream. C. linduensis is also sympatric with the recently described species Caridina dali and Caridina kaili.
