Yellow tail brook barb Poropuntius deauratus is one of the earliest described ﬁsh species in Vietnam since 1842 by Valenciennes. This barb is one of ﬁshes occasionally marketed fresh as local food where they were recorded and sometimes seen in aquarium trade. This barb occurs in medium size and small rivers and streams, in clear water with rapid current. With adapt features in restricted habitats; brook barb P. deauratus is vulnerable to habitat’s changes caused by dam construction, water pollution, and overﬁshing (Freyhof 2011). Correspondingly, P. deauratus are assessed as Endangered on IUCN Red List. They occur in Central Vietnam only (Serov et al. 2006). However, in some studies, this species are recorded from Cambodia, Thailand (Rainboth 1996, Kottelat 2000), China, Laos (Baird et al. 1999) and Malaysia (Ng and Tan 1999, Shah et al. 2009). Is the distribution of P. deauratus precisely? Robert (1998) indicated that misidentiﬁcation between P. deauratus and P. normani. Poropuntius deauratus was also described with differences of caudal-ﬁn morphology (Valenciennes 1842, Rainboth 1996, Serov et al. 2006). Therefore, the study on taxonomy of P. deauratus is necessary to investigate precisely its distribution. This will assist to establish the protected areas for P. deauratus’ conservation.
Poropuntius deauratus will be collected from river drainages in Central Vietnam, and compared with specimens from Thailand, Laos, and Cambodia. From 2019 to 2020, field surveys will be conducted in rainy and dry season. Project sites are streams and rivers where are high elevation and characteristic by lotic habitats include three types: pool, run, and riffle. Fish specimens will be collected directly by local fishermen and indirectly from local fish markets. The detail distribution information is collected including latitude, longitude, and ecological parameters where P. deauratus occurs. Specimens are identiﬁed by using taxonomic literatures combine with DNA barcoding.
The results of P. deauratus’ identification provide primary information to determine the correct species and distribution areas of P. deauratus in the wild. Distribution information will be disseminated to management and local people in the form of reports, maps, publications, posters, and workshops. Through the project, we expect to improve local community awareness and practices on the value of natural fish resources for this species and their habitats conservation. Distribution information will be published in conservation journal by English language provide to management, scientists to create highly conservation effect for this species in the Southeast Asia region.
