Mogurnda mosa

Declining

Overview

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

Mogurnda mosa faces severe threats from habitat degradation and water quality decline in its limited freshwater range. Agricultural runoff and urban development have significantly altered water chemistry and sedimentation patterns in the streams where this gudgeon occurs. The species' restricted distribution makes it particularly vulnerable to localized environmental changes, with pollution and habitat modification representing the primary drivers of population decline.

Threat summary

Habitat
