Anal soft rays: 85. Dorsal fin missing. Habitat:
This species inhabits rivers and major streams, and
can also be found in lacustrine habitats. Diet:
Stomach contents consist of small fish and prawns.
Processed as smoked fish. Remarks:
Although there is no detailed information on the population
size and trend of this species, it is still abundant
throughout its known distribution and the population
trend is thus suspected to be stable or declining
at a rate that precludes it from a threatened catgory.
While there may be localised or regional threats,
they are unlikely to affect this species on a range-wide
scale, and it is found in at least one protected area.
Therefore, it is assessed as Least Concern. (IUCN
