Lates mariae

Declining

Overview

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

Lates mariae faces severe population decline primarily due to overfishing and the introduction of non-native species in Lake Turkana. The species has experienced dramatic reductions in catch rates, with commercial fishing pressure targeting this valuable food fish. Habitat degradation from increased sedimentation and water level fluctuations in Lake Turkana further threaten the remaining population.

Threat summary
