Red Canarese Barb

Hypselobarbus thomassi

Unknown

Overview

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

Hypselobarbus thomassi faces severe population decline primarily due to extensive dam construction and river modification throughout its native range in the Western Ghats. Sand mining and quarrying activities have degraded critical spawning habitats, while agricultural runoff and domestic pollution have compromised water quality in remaining river systems. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction and hydrological changes.

Threat summary

Habitat

This freshwater fish inhabits fast-flowing rivers and streams in the Western Ghats of India, particularly favoring rocky substrates and well-oxygenated waters. The species requires specific spawning grounds with gravel beds and is adapted to the seasonal flow patterns of monsoon-fed river systems.
