Distribution

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).

Diagnostic Description

Differs from A. mucronatum, A. murraystuarti, A. platycephalus, A. foratum and A. variegatum in having a relatively short body with 34-36 (versus 38-40) vertebrae, and a caudal fin with upper and lower lobes fo distinctly different shapes (versus truncate caudal fin in A. murraystuarti and with both lobes similar in shape in other Indochinese species). Pectoral spine smooth (Ref. 37785).

Ecology

Habitat

Habitat and Ecology

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.

Justification
Although some anthropogenic threats to this species have been documented (Prasad et al.1997), these are deemed to be speculatory and not based on hard evidence. Given that this species is relatively common and abundant throughout the sub-Himalayan region (in the Ganges and Brahmaputra river drainages), Amblyceps mangois is assessed as Least Concern here.

Threats

Major Threats

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.

Management

Conservation Actions

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).
