Anabarilius andersoni

Declining

Overview

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

Anabarilius andersoni faces severe population decline primarily due to water pollution from agricultural runoff and industrial discharge in its native Chinese lake systems. Dam construction and water diversion projects have significantly altered natural water flow patterns, fragmenting remaining populations. Overfishing and the introduction of non-native fish species have further reduced breeding success and juvenile survival rates.
