Haplochromis percoides
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Haplochromis percoides faces severe threats from the introduction of Nile perch (Lates niloticus) into Lake Victoria, which has caused dramatic population declines through predation and competition. Eutrophication from agricultural runoff and sewage has degraded water quality and reduced oxygen levels in the lake's deeper waters where this species historically occurred. Overfishing using fine-mesh nets has further reduced population numbers, while habitat modification from shoreline development has eliminated critical breeding areas.
Habitat
This endemic cichlid inhabits the deeper rocky and sandy areas of Lake Victoria, typically found at depths of 10-40 meters. The species prefers areas with moderate water flow and rocky substrates that provide shelter and feeding opportunities among algae-covered surfaces.
