Population: More research is needed to investigate the possibility of natural population in India.
Current Population Trend: Unknown
Additional data:
? Continuing decline of mature individuals: No
? Extreme fluctuations: Unknown ? Population severely fragmented: Unknown
? Continuing decline in subpopulations: Yes
Habitat and Ecology [top]
Habitat and Ecology: The species is found in rivers and lakes. It is a local migrant.
Systems: Freshwater
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 1.5-3.3
Movement patterns: Full Migrant
Use and Trade [top]
Use and Trade: It is commercially used as food from captive breeding in Manipur. In Myanmar it is also used but from the wild.
Threats [top]
Major Threat(s): The extinction of this species in Manipur was due to construction of dams, habitat degradation and introduction invasive species which caused fragmentation. Threats to this species in Myanmar are unknown.
Conservation Actions [top]
Conservation Actions: More research about the distribution and the biology of this species is needed, as there is insufficient information available. The effects on the population of collecting for the ornamental fish trade also need to be fully ascertained. Other potential threats to this species also need to be identified in Myanmar. Surveys in Manipur are recommended.
