Schistura susannae

Stable

Overview

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

Schistura susannae faces significant pressure from habitat degradation in its limited range within the Mekong River basin. Dam construction and water diversions alter the natural flow regimes essential for this stream-dwelling loach, while agricultural runoff and domestic pollution degrade water quality in the clear, fast-flowing streams it requires. The species' restricted distribution makes it particularly vulnerable to localized environmental changes.

Threat summary

Habitat

This freshwater loach inhabits clear, fast-flowing streams and tributaries within the Mekong River system. It typically occurs in rocky substrates with good water flow and high dissolved oxygen levels.
