Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2009-12-26
Assessor(s): Ng, H.H.
Reviewer(s): Jha, B.R. & Molur, S.
Contributor(s): Molur, S.
Justification:
Batasio macronotus is known only from very few localities in Nepal and is presumed to be distributed more widely that what is known. The population size and trend for this species remain unknown and this species is only known from scanty museum records. There is also very little information on the biology of this species and potential impacts of threats (especially those of an anthropogenic nature). Therefore, there is insufficient information to accurately assess this species and it is considered Data Deficient at present.

Population: There is no information on the population and its trends for this species.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species has been found in large rivers with turbid water, overlying mainly sand substrate in lotic areas, and sand/mud substrate with some submerged and emergent vegetation in lentic backwaters (Ng and Edds 2004).
Systems: Freshwater

Use and Trade [top]

Use and Trade: This species is of limited value as a food fish in artisanal fisheries.

Threats [top]

Major Threat(s): 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.

Conservation Actions [top]

Conservation Actions: There is insufficient information on the distribution, biology and potential threats for this species.
