Description |
JUSTIFICATION
This species is assessed as Data Deficient due to the lack of information concerning its population size and trends, distribution, biology and potential threats.
RANGE DESCRIPTION
The species is known from the rivers draining the eastern face of the Annam mountains from the vicinity of Hue in central Viet Nam northwards to the Red River drainage in northern Viet Nam and southern China, the Zhujiang (Pearl River) drainage in southern China (Guangdong, and Fujian), and the river drainages on Hainan Island. Records of this species from central and northern China require verification. Described from Kachek [=Jiaji], Hainan Island off the coast of southern China (Oshima 1926). Chan and Ho (2011) report the species from Hong Kong, but suggest that it has been introduced via water supplies from Guangdong.
DESCRIPTION
There is no information available on the population and its trends for this species.
HABITAT AND ECOLOGY
This species typically inhabits upland rivers, typically with a moderate current and a substrate of sand/gravel. It is a benthic species, preferring streams with rocky and sandy bottoms. It is nocturnal and feeds mainly on worms, small aquatic insects and crustaceans.
THREATS
The threats to this species are unknown, since there is no information on the biology of this species and therefore the impact of potential threats (especially those of an anthropogenic nature) remains unknown. The current threats to aquatic biodiversity in all of its known distribution have also not been adequately identified.
USE AND TRADE
This species is consumed for food and is occasionally harvested for the aquarium trade.
CONSERVATION ACTIONS
There is insufficient information on the population and its trends, distribution, biology and potential threats for this species. |
