St. Lucia Mullet

Liza luciae

Unknown

Overview

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

The St. Lucia Mullet faces severe population decline due to its extremely restricted range, being endemic to a single freshwater lake system on the island of St. Lucia. Habitat degradation from agricultural runoff, sedimentation, and water pollution poses the primary threat to this species. The introduction of non-native fish species has created additional competitive pressure, while the species' limited dispersal ability makes it particularly vulnerable to localized environmental changes.

Threat summary
