Population [top]

Population: Although there is no information on the population and trend for this species, G. melanopterus is a relatively abundant species throughout Myanmar (it was the most abundant species taken at its type locality; Roberts and Ferraris 1998) and the population can be considered to be stable at this moment.
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits larger rivers with muddy bottoms (Vidthayanon et al. 2005), particularly in the lower reaches (Roberts and Ferraris 1998).
Systems: Freshwater
Continuing decline in area, extent and/or quality of habitat: Unknown

Use and Trade [top]

Use and Trade: This species is occasionally exported as an ornamental fish, and is commonly sold as a food fish in markets in Myanmar (Vidthayanon et al. 2005).

Threats [top]

Major Threat(s): 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.

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.
