Barilius dimorphicus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Songi bariil faces severe pressure from dam construction and water diversions that fragment its riverine habitat and alter natural flow regimes. Pollution from agricultural runoff and domestic waste degrades water quality in its native river systems. Overfishing and destructive fishing practices using explosives and poisons have significantly reduced population numbers across its range.
