Overview

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

Dromus dromas faces severe population decline primarily due to habitat degradation from agricultural runoff and sedimentation in its freshwater mussel beds. Dam construction and river channelization have fragmented populations and altered the natural flow regimes essential for reproduction. The species' dependence on specific fish hosts for larval development makes it particularly vulnerable to declining fish populations from water pollution and overfishing.

Threat summary

Habitat

This freshwater mussel inhabits clean, flowing rivers and streams with stable gravel and sand substrates. It requires well-oxygenated waters with minimal sedimentation to maintain healthy mussel bed communities.
