Cyprinus ilishaestomus

Declining

Overview

Cyprinus ilishaestomus is a species of ray-finned fish in the genus Cyprinus. Critically endangered, it inhabits Qilu Lake, Yunnan, China.

Cyprinus ilishaestomus faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development in its native river systems. Dam construction has fragmented its spawning grounds, while introduced species compete for resources and alter the aquatic ecosystem. Water pollution from industrial activities has further compromised water quality in the limited watersheds where this species persists.

Threat summary

Habitat

This freshwater cyprinid inhabits slow-moving rivers and associated wetlands in specific watershed systems. It requires clean, well-oxygenated waters with suitable spawning substrates and riparian vegetation cover.

Frequently asked questions

Why is Cyprinus ilishaestomus classified as Critically Endangered?
Cyprinus ilishaestomus 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. Cyprinus ilishaestomus faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development in its native river systems. Dam construction has fragmented its spawning grounds, while introduced species compete for resources and alter the aquatic ecosystem. Water pollution from industrial activities has further compromised water quality in the limited watersheds where this species persists.
Where does Cyprinus ilishaestomus live?
Cyprinus ilishaestomus occurs in China. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cyprinus ilishaestomus?
The main threats to Cyprinus ilishaestomus are 2.1, 7.2, 9.1, and 9.3.4. The full IUCN-classified threat record for this species is detailed on the species page.
