Scientific Name: Chandramara chandramara
Species Authority: (Hamilton, 1822)
Taxonomic Notes: Chandramara chandramara was described from the Atrai River in northern Bengal (Hamilton 1822).  This species is similar to members of the genus Batasio, from which it differs by its relatively smaller size, mottled, translucent body and fewer vertebrae (34–35).  The generic assignment of this species remains unclear, and Chandramara may be a synonym of Batasio (Mo 1991).  Rama rama (Hamilton, 1822) has been sometimes thought to be a valid species (e.g. Ferraris 2007), but is more likely a synonym of C. chandramara.  This awaits further investigation.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-10-05
Assessor(s): Ng, H.H.
Reviewer(s): Nguyen, T.H.T., Chaudhry, S. & Molur, S.
Contributor(s): Molur, S.
Justification:
Despite being harvested as an ornamental fish and the lack of information regarding population size and its trends, Chandramara chandramara is still relatively common and the level of exploitation is not deemed high enough to be a threat to long-term survival of this species.  It is therefore assessed as Least Concern here.

Geographic Range [top]

Range Description: This species is recorded from Brahmaputra River drainage in Arunachal Pradesh, Assam, Meghalaya and West Bengal in India, and Bangladesh (W. Vishwanath, S.C. Dey, S. Chaudhry and H.H. Ng pers. comm.).

Population [top]

Population: The population seems to be stable in upper Assam in the Brahmaputra River (S.C. Dey pers. comm.).  There is no information on the population and its trends for this species in other areas of its range (H.H. Ng pers. comm.).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits rivers with a sandy or muddy bottom (H.H. Ng pers. comm.).
Systems: Freshwater

Use and Trade [top]

Use and Trade: This species is caught mostly from upper Assam and exported as an ornamental fish through Kolkata (S. Chaudhry pers. comm.).

Threats [top]

Major Threat(s): Collection for aquarium trade is a potential threat to the species in some areas of its distribution.  Other 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.

Conservation Actions [top]

Conservation Actions: There is insufficient information on the distribution, biology and potential threats for this species.  The taxonomy of this species also requires further study and the conspecificity of Rama rama with this species awaits verification.
