Hyalobagrus ornatus

Unknown

Overview

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

Hyalobagrus ornatus faces severe threats from rapid deforestation and agricultural expansion throughout its limited range in Southeast Asian river systems. Dam construction and water diversions have fragmented its riverine habitat, while sedimentation from logging activities degrades water quality essential for this specialized catfish. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction.

Threat summary

Habitat

This catfish inhabits clear, fast-flowing rivers and streams in tropical Southeast Asian forest watersheds. It requires well-oxygenated waters with rocky or sandy substrates, typically found in undisturbed primary forest catchments.
