Haplochromis barbarae

Declining

Overview

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

Haplochromis barbarae faces severe threats from the introduction of Nile perch (Lates niloticus) into Lake Victoria, which has caused dramatic population declines across endemic cichlid species. Eutrophication from agricultural runoff and sewage has degraded water quality and reduced oxygen levels in critical breeding areas. Overfishing and destructive fishing practices have further reduced population numbers, while habitat modification from shoreline development has eliminated important shallow-water nursery areas.

Threat summary

Habitat

Haplochromis barbarae is endemic to Lake Victoria, where it inhabits shallow rocky and sandy shores with moderate vegetation cover. The species prefers areas with stable substrate for breeding and foraging, typically at depths of 2-10 meters in well-oxygenated waters.
