Aborichthys garoensis is considered to be Vulnerable since the extent of occurence < 20,000 km2 accompanied by habitat destruction (due to siltation caused by deforestation and agricultural development).  This assessment should be revisited if further inforamtion becomes available on the species taxonomy (given the unconnected currently known populations), distributions, and threats.


Geographic Range [top]

Range Description:Aborichthys garoensis is known from the Garo Hills, Meghalaya (southern tributary of the Brahmaputra) and Dikrong River (northern tributary), Arunachal Pradesh, India (W. Vishwanath pers. comm.).  No information is known on presence in intermediate basins.
Countries occurrence:
India (Arunachal Pradesh, Meghalaya)
Continuing decline in extent of occurrence (EOO):Unknown
Extreme fluctuations in extent of occurrence (EOO):Unknown

Population [top]

Population:No information is available on the species population.  Species may be affected by change in their habitat.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species is found to occur in streams with pebbly bottoms; a moutain stream specialist requiring clear oxygenated water.
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: This species attains a length of 3.8 cm and is of no interest to fisheries.

Threats [top]

Major Threat(s): Being a hillstream fish, the species is prone to habitat destruction caused by deforestation and siltation during monsoon season.

Conservation Actions [top]

Conservation Actions:

The species is not known from any protected areas, and clearly there is a need for improved habitat protection at sites where this species is known to occur. Further survey work is needed to determine whether or not this species is experiencing a decline, or is undergoing natural population fluctuations.
