Percichthys melanops

Declining

Overview

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

Percichthys melanops faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development around its native lake systems in Chile. The introduction of non-native salmonid species has created intense competition for food resources and spawning sites. Dam construction and water extraction for irrigation have significantly altered the natural flow regimes and water levels critical for this endemic fish's reproductive cycle.

Threat summary

Habitat

This endemic Chilean fish inhabits cool, clear freshwater lakes and their associated tributaries in the central Chilean lake district. It prefers well-oxygenated waters with rocky or gravelly substrates, typically at elevations between 200-800 meters in temperate lake ecosystems.

Frequently asked questions

Why is Percichthys melanops classified as Critically Endangered?
Percichthys melanops 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. Percichthys melanops faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development around its native lake systems in Chile. The introduction of non-native salmonid species has created intense competition for food resources and spawning sites. Dam construction and water extraction for irrigation have significantly altered the natural flow regimes and water levels critical for this endemic fish's reproductive cycle.
