|Scientific Name:||Sisor rabdophorus Hamilton, 1822|
|Taxonomic Notes:||Sisor rabdophorus was originally described from the rivers of Bengal and Bihar (Hamilton 1822). Previously thought to be widely distributed in the Brahmaputra, Ganges and Indus river drainages, this species was shown to be more restricted in distribution (the lower Ganges drainage) by Ng (2003), who designated a neotype (from the Bhagirathi River, a distributary of the Ganges in West Bengal) for this species. It is likely that material identified as this species from the Indus River drainage is not conspecific.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Allen, D.J., Vishwanath, W., Dahanukar, N. & Molur, S.|
Although there is insufficient information on the population size (and trends) and the biology of this species, data from field surveys indicates that this species is still relatively common. Coupled with the fact that this species is not eaten and is only collected for the ornamental fish trade at low harvesting levels, Sisor rabdophorus is assessed here as Least Concern.
|Range Description:||This species is known from the lower Ganges River drainage.|
Native:India (West Bengal)

There is no information on the population and its trends for this species. However, data from recent field surveys suggest that it is still relatively common in the lower Ganges River drainage.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species inhabits swift rivers with a substrate of sand and/or gravel.|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Use and Trade:||This species is sometimes caught and exported as an ornamental fish.|
The threats to this species are unknown, since there is little 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.
More research about the distribution and the biology of this species is needed, as there is insufficient information available. Potential threats to this species also need to be identified.
