Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2011-01-12
Assessor/s: Kottelat, M.
Reviewer/s: Gibson, C. & Allen, D.
Justification:
This species is known from southeastern Thailand, in coastal drainages from Chonburi to Trat provinces. It is recorded from the Xe Kong drainage (a Mekong tributary) in Lao PDR and is assumed to be in the same drainage in Cambodia and possibly in Viet Nam. It inhabits streams with moderate flow, preferable under forest cover, or in swampy areas. It lives on the bottom, among plant roots or in leave litter. It covers a relatively wide geographic range. A variety of threats are present throughout its range in Thailand. The threats are much less marked in Lao PDR and, probably, in Cambodia. Therefore it is assessed as Least Concern. An analysis of the impact of the utilization for the aquarium-fish trade would be justified.

Geographic Range [top]

Range Description: This species is known from southeastern Thailand, in coastal drainages from Chonburi to Trat provinces, and has been recorded from the Xe Kong drainage (Mekong tributary) in Lao PDR and the Mekong delta in Viet Nam (Kottelat and Lim 1993, Baird 1999, Kottelat 2001). It is therefore assumed to also be present in Cambodia.

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It inhabits streams with moderate flow, preferable under forest cover, or in swampy areas. It lives on the bottom, among plant roots or in leaf litter.
Systems: Freshwater

Threats [top]

Major Threat(s):

Anthropogenic modification of river morphology impacts this species by reducing or interrupting fast water flow and causing sedimentation. Most of its range in Thailand is in intensely cultivated areas and this results in pollution, eutrophication, water abstraction, interruption of the flow in stream, channelisation. The combined impact of these activities on small streams is not quantified but is visible. The impact of the captures for the aquarium fish trade has not been investigated.

Conservation Actions [top]

Conservation Actions: No conservation actions are in place. An analysis of the impact of the utilization for the aquarium-fish trade would be justified.
