Haplochromis nanoserranus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Haplochromis nanoserranus 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 continues to eliminate spawning grounds.
Habitat
This endemic cichlid inhabits the rocky shores and shallow waters of Lake Victoria, typically found at depths of 2-15 meters among boulder fields and rocky substrates. The species prefers areas with moderate water flow and abundant algal growth, which provides both food resources and spawning sites in crevices between rocks.
