Assessment Information [back to top]
Category Least Concern (LC)
Criteria Least Concern (LC) ver 3.1
Justification Eutropiichthys vacha is widely distributed in freshwater and coastal rivers. Current data suggests that this species is still relatively abundant in all over Bangladesh. Though, population might be declining locally in some areas due to overexploitation and habitat destruction, recent information indicates it has much greater area of EOO (2,20,042.27 km²) and AOO (10,587.65 km²). Therefore, this species is assessed as Least Concern.
Date Assessed 25/06/2014
History It was assessed as Critically Endangered in IUCN Bangladesh (2000).
