Population Information

This species is now very rare in the lower Bang Pakong River drainage. Only a few individuals have been caught in the Bang Pakong River in the past ten years (C. Vidthayanon pers. comm. 2011). The actual population decline rate is unknown, however major pollution has occurred since 2005 and based on this species' sensitivity and current very low population levels it is suspected that it has declined by more than 80% over the past 10 years.


This species is sensitive to pollution from industrial, domestic and agricultural sources, which is occurring in the lower Bang Pakong River drainage. The levels of pollution have increased significantly since around 2005.
