Triplophysa gejiuensis

Unknown

Overview

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

Triplophysa gejiuensis faces severe threats from mining activities and industrial development in the Gejiu region of Yunnan Province, China, which have contaminated its freshwater habitats with heavy metals and altered water chemistry. Urban expansion and agricultural runoff have further degraded water quality in the limited stream systems where this endemic loach occurs. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes and pollution events.

Why is Triplophysa gejiuensis classified as Critically Endangered?
Triplophysa gejiuensis is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Triplophysa gejiuensis faces severe threats from mining activities and industrial development in the Gejiu region of Yunnan Province, China, which have contaminated its freshwater habitats with heavy metals and altered water chemistry. Urban expansion and agricultural runoff have further degraded water quality in the limited stream systems where this endemic loach occurs. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes and pollution events.
Where does Triplophysa gejiuensis live?
Triplophysa gejiuensis occurs in China. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
