Description |
Asia: Pakistan to Thailand.
Geographic Range [top]
Range Description: This species is known throughout the Ganges and Brahmaputra River drainages in India, Nepal and Bangladesh. Although also reported from the Indus River drainage in Pakistan, the conspecificity of this population needs further investigation (H.H. Ng pers. comm. 2010).
Countries occurrence:
Native:
Bangladesh; India (Arunachal Pradesh, Assam, Bihar, Himachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, Uttar Pradesh, West Bengal); Nepal

Population [top]
Population:
The population size and trend of this species is unknown. However, current evidence indicates that this species is relatively abundant throughout the subHimalayan region. In Nepal, this species has been encountered at 0.17 CPUE (Jha 2009)
Current Population Trend: Unknown
Additional data:
?Continuing decline of mature individuals: Unknown
?Population severely fragmented: No
Habitat and Ecology [top]
Habitat and Ecology: This species inhabits torrential streams and rivers with a substrate of rocks and pebbles, spending most of its time amongst the crevices. It is also said to be able to survive the drying up of the streams and living in pool-type habitats (Prasad et al. 1997). Amblyceps mangois is capable of breathing air (Singh et al. 1989), which is what enables it to survive the lower oxygen content of the pool-type habitats.
Systems: Freshwater
Use and Trade [top]
Use and Trade: This catfish is occasionally caught and exported as an ornamental fish. It is encountered as bycatch in artisanal fisheries of cobitid loaches (Prasad et al. 1997).
Threats [top]
Major Threat(s):
The threats to this species are unknown, since 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. Although Prasad et al. (1997) identified habitat modification via the removal of river substrate (for construction) and overfishing as accidental bycatch as major threats for this species, no empirical studies have been conducted on the effects of either of these supposed threats on fish populations. These are deemed to be based on speculation on should not be considered here.
Conservation Actions [top]
Conservation Actions:
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, and its effects on populations of this fish better understood. the species has been assessed as Endangered in India (Lokra et al. 2010).
